 Hello everybody, welcome back to Retro Tech and today I'm going to be doing a comments and questions video So let's just go ahead and dive right into these questions I've got a couple good ones here first comes from big boss and this is on the howly the recent video on how to calibrate a JVC HR CRT the professional video monitor and Big boss says wish you did a video on a consumer CRT like D-Series or L art JVC on the consumer side is really limited on the service menu and how to adjust the yoke He says his is sealed with a nut and epoxy around the note the nut and he can't get it off to adjust Okay, so first off you can probably try to safely peel that epoxy just slowly work it off And you still can adjust your yoke most likely the same way But I do plan on doing some content eventually down the road on consumer CRTs as I Have them available in my shop I did want to talk about a couple of videos that I do have it coming up right away And first one is the other JVC video. I've got two more videos on the little JVC Which is the one that I did the calibration video I appreciate everybody watching the calibration video because let's face it a lot of people probably don't have that monitor And we're just trying to learn more about calibrating CRTs by watching it And I really appreciate you watching it But this one is going to go into all the details on the JVC monitor And give you a lot of background on it what specific features it offers And a little bit on how it compares to other Pro video monitors And then after that one, I've just got a cool little Really more of an art style video coming after that on the JVC And that'll be it for that little JVC monitor Most videos are already done and shot. So here is the D series that I've got it's currently in my shop And you've probably seen it in the background. It's got some interesting stories behind it So I'm going to do a video on that eventually However, I'm going to have a big project coming up really soon And that's another monitor restoration project. I recently got two more monitors in the mail And I've got videos showing more details on that But the first one is this M4U right here And then the other one is a BVM. It's a D series BVM. So it's a 14 inch It's BVM D14H5U. So I'm really excited. This thing has a A lot of issues with it and it's going to need a full restoration I mean full as far as you're going to get as a restoration video is going to be concerned We're going to do it to this BVM. I've even got a new bezel to install We're going to install a new tube in it capacitors Everything that we can possibly do this and we will be doing to it And then that's going to be it for what's coming up So I will again do a video series eventually on that D series. That's why I've got it And when I do that video, I will include how to calibrate it And walk you through the back of it like I did the other monitors So unfortunately you just have to kind of hang out and wait for me to catch up to all those I apologize, but I just kind of got to do some things in the order that I need them done in severity So just keep keep with the channel and eventually we'll get to the D series All right, so my next question actually came from facebook and this one was sent to me from another viewer So hello, please excuse my disturbance my sony bvm a 20 f 1 m Has the standby led blinking for 15 times Then the operation led stays on for 10 seconds Then again the standby blinks 15 times. Have you come across this problem? and unfortunately The a series is kind of a dubious and Troublesome Bvm monitor for anybody to really buy that's not an experienced technician for the most part So I tell everyone to try to avoid the a series unless It absolutely just falls into your lap and here's a quick look at what an a series looks like So it looks a lot like any of the other bvms you'll see and it's also one of the last It is the last model line made so you'd think oh well So technology more technology in it which there is But you do have to keep your eyes up for these these first off if you notice There's no control buttons on it like there are on other bvms So you have to have a control unit now sometimes they'll be built in with a bkm kit But a lot of times they won't So you'll always have to check if you do run into an a series if if it comes with a control board then And this is just to start with so you've got the a that board But if you look around back on the a series This is one of the biggest issues with the a series overall and most people know this it's this analog board It's pictured. This is a bkm 68x and if you just research a little bit about it It is very difficult to get one of these save on pat Said that I think there's somewhere around maybe 300 of these or ever even made this bkm 68x board i'm not sure that For certain so if anybody does know the exact run they can leave that in the comments but it is an extremely rare board and Since it is it's only comes available for sale very rarely and when it does it's thousands of dollars I mean three thousand dollars sometimes So that's another reason to completely avoid this monitor because that is the only way to get rgb or component Into this bvm. It's the only way. There's not a replacement card out there And there is not a mod that's available or anything like that right now for this monitor You have to have that 68x card to even get rgb or component now There are other boards you can get now if you do come across one of these And it's an extremely good deal There is one good thing to keep these for and that is for the tube that's inside of them Because most of the time the tubes inside of them do not Go bad because they haven't been used very often most times And they can be switched from this model over to d series So it's very valuable to keep the monitors just for the tube inside of them Because there's and then hope and pray that you run across a d series That someone is selling with a bad tube And then you might be able to get a good deal on a d series by having a tube from an a series going installing it into the d series But let's get back to this guy's problem where he's having problems with it shutting off and overloading And honestly, this is one thing I've been wanting to bring up that most of the problems you have With power issues where the monitor will turn on for a second and this could be any CRT monitor 90 percent of the problems are in the power supply and that's Where the problems are with the capacitors they dry out over time and they do not Work and allow the same amount of current, you know to Travel through them and they lose their functionality all together over time So the majority of power supply issues or power issues on a pvm is because the power supply Has bad components in it and most of the time 90 percent of the time it's capacitors Now you will if it's not the capacitors you change the capacitors and you still have an issues then it's obviously something else But that's pretty much where we always start if there's a power issue is with that power supply And then it could be another thing that's gone bad on the power supply. Maybe an ic or something But most of the time 90 percent of the time it is a power supply issue that causes power issues and standby modes and things like that to occur It's not always that but that's a most of the time where we're going to start for diagnostics You can get replacement power boards for most pvms Just check with the service manual for your pvm and see which ones are similar to that And then you may be able to find a replacement power supply unit and just replace the whole unit And then you can maybe get the old power supply rebuilt and sell it back or you know trade it or use it But that's where the majority of the problems is one last thing about the a series And I know i've been talking about this one a little bit longer than it probably should The a series also has firmware updates that are If the if it's not been properly set up to begin with It can keep it from even powering on and it's all just because of a firmware update That needs to be uh, you know these things need to get updated firmware So occasionally you'll get one and it won't even shut it won't even turn itself on Or won't function and it's again because of a firmware issue So these a series had a lot of problems with them as far as like compatibility issues because they're right on the cusp Of the hd era and the flat screen lcds and all that stuff. So That's pretty much it for that one now. I've got my third question here. It comes from jim and this is an email so Okay, so he immediately has a question down jim had recently gotten a power supply cap kit for his 1953 md And he says here he got everything apart trying to make sure and he's getting ready to replace the capacitors That's just some background here He's going through the cap list it started with the biggest caps and you immediately noticed that he had an extra capacitor and after Looking at the board compared to the capacitor kit. He noticed that he actually had three extra capacitors And so he's he started working. We started discussing this was something I wanted to bring up He was nice enough to include a picture here So you could see this cap kit actually included some of these caps that were not Populated on his board and he's got some more parts here that are not Populated on this board. So this can occasionally happen because again, this is a power supply So in a 20 year old monitor, you could have had a technician come in and swap a power supply from another monitor Or a compatible monitor that happens to have unpopulated Things here because maybe the monitor wasn't or this power supply wasn't set up to do the same things or all the functionality of another higher rated power supply So this is an interesting thing that there's different power supplies that can work for different monitors And because where I got the cap kit that was developed was straight from the manual For this monitor. So Jim may have had a cap kit or not a cap kit But he may have had a technician at some point come in and install a separate new power supply within his pvm Or it could have come with a lower rated power supply out of the manufacturer's facility for some reason Either to save cost is maybe like a cost savings option to the person who bought this originally That's also a possibility. So this is just something I want everybody to be made sure of because I was kind of surprised by this a little bit Although I had seen it before I've not seen it where there's actually three or four capacitors that were left Completely unpopulated. So if you see this Don't be concerned with adding the parts back if it came out of your monitor and it was functioning to begin with Then you can leave it the way it is because this is obviously a factory setup Where somebody didn't just remove the parts themselves. It was done like this from the factory so Anyway, that's it for this episode of comments.
