  • Only use genuine Sanyo convergence chips when doing repairs on projection TV sets. You can get parts and detailed repair instructions from sites like Tv Repair Kits . com

  • I did what you instructed on pushing and turning the red wire to disconnect from the wires in seriesand it came out and didn't break,now my problem is the circuit board on the right side is under 5or 6 little black tabs that I can't free the board from .Raised the 4 white bridges and took out the screws on board,but it won't slide away from the black tabs.Thanks again I have 2 the same model and both boards need to come out

  • @chevy56123 Shoot me an e-mail/pm here with a picture of what your describing. The hard part is over.

  • Thank you much for the tips and thank you for the quick reply.Thank you

  • I need to get my convergence board out but the 2 red wires connected to the fly back won't come off to free the board.I tried to push and turn them like you said but won't come out.I really think I could fix this if I could get the board out.Thanks

  • @chevy56123 The smallest wire to mine was actually just an exposed bare wire friction fit. When I pulled the others and broke them I thought I was looking at the same thing on a larger scale. It really is a dumbass design. The only thing you can do is pry them out with pliers (grab tight and make a fulcrum for leverage) and just break them loose. Then back out the cap with the appropriate sized drill bit. Desolder the hole. Place the cap back on the wire and solder and trim the wire flush.

  • @chevy56123 Mark the wire first so you get the correct depth and you know exactly where the end was sitting. Then you'll have to tie the wires back in place like you see the two I did there to seat them to the proper depth. Because after you force them out they won't stay in place on their own.

  • i have a sony 48" projection tv in my room i just got and the picture looks good like the blue and the green are inline but the red is off some.. on the left of the screen theres a red shaddow below everything and on the right of the screen the red curves down like to the corner of the screen, i tried adjusting the lences and everyone says to get new convergences but do you think that is the problem? only the red is messed up is there an easier fix for my problem?

  • @countryboyG Red was the same one that went on mine..Nope its one of your chips..Its not a bad fix just a bit time consuming..Then again more than half the work was cleaning the coolant off the one mainboard..Well and pulling that lamp to add coolant..Just be sure to order exactly what you have (code number right on them) and don't upgrade or you'll have to change all your resistors..Get them from Bluestar..I think they were 6 bucks each but of course I had to overnight them..get her done..

  • @MrChondro what chip? where is it at on the board? what does it look like? im new to all this.

  • @countryboyG at 7:27 I pick up the chips..The old ones are on the left and the two new ones are stuck back to back into the piece of foam on the right. At 7:53 if you pause it you can see the two heat sinks that they screw to. No matter your configuration they'll look very close to mine.Some are very easy to access while others like mine require removing the whole board. Some are on a small seperate board right in the front when you remove the back panel and really make life easy.

  • @countryboyG All you have to do is remove the board they are on and desolder the old chips and then solder in the new ones. Just be sure to put some good thermal paste (artic silver if you can find it) between the chips and heat sinks before you screw them to the heatsink. There are some really good vids up on how to desolder and solder if your new to it. It could just be a fuse or resistor..check those first..95% of the time its the chips..

  • @countryboyG mrchondro I know your new to fixing tvs as i am i just have one question did you have any problems discharging the flyback. I can see in this video that you took the wires off and even broke one of the tips did you have to discharge it so it would not shock you or was it ok just to leave it unpluged for a few hours??

  • this sounds like jack Nicholson fixing his tv. lol, good vid tho.

  • @TheChaaban Thanks..When I do my follow up with this one I'll do my best Nicholson impression "I'd rather needles my eyes"..forget which movie of his that was from.

  • I actually broke off the one little tab that helps you pull it up. I tried bringing a wire tie underneath and around. Then pulling on the wire tie while lifting on the tab definately helped. You still have to be careful because the wire tie snapped and I pulled one of the white tab wires almost out. It was definately very difficult. Wondering if there is a tool you can use.

  • @sallsto I'd have to get in there in look again..Based on the e-mails I've gotten I should do a follow up video and be more precise. I think I just used a larger pair of needle nose pliers that have the ridges on them..that has a better grip surface to grab it. But instead of pulling up you just grasp it and pivot to the left or right depending on the side that is connected.

  • I think i may have the same tv. with the same problem. What was yours doing? I think my IC's are overheating and putting it into safe mode(turning it off, Blinking light) Is this a panasonic? I don't see any bad resistors and they all seem to be testing in range. Thanks for your help @sallsto 

  • @fordbullittboy Yes this is a panasonic. My convergence was off..one of the chips died but they are so cheap you may as well do both at the same time. I'm running a CPU fan over top of the heatsinks that the chips are connected to..Had they used a better thermal paste and more this most likely woudn't have happened..The chips were running 177F and now with the fan they are running at 114F. I didn't know what to piggy back the fan off of so just running it off of a 12 volt rechargeable battery.

  • How did get the white connectors apart that connects the 2 board together. You mentioned it in the video but you didn't show how you got them apart. Having a heck of a time. Afraid i am going to break them.

  • @sallsto If you look you'll see that they stay connected to one of the boards. Look closely and you'll see which side comes up. Just use a flat screwdriver or small pliers and bring the bridge straight up..It does take a bit of force. This is one component that is stronger than it looks..

  • bubbles in the coolant , deflection board has copper sulfate , you took it all apart ,

    needs crts , you have to push and turn the anode wires, No your not a complete moron. Reposting your video with this at the curb will make your moronism complete

  • You shouldn't apologize so much, this was a good video. I see that one of your capacitors blew out on the convergence board. Ya might wanna replace that too.

  • @purp13 Thanks..The first time I shot it the phone continued to ring so I had to do it over quick..With the second unit out in my garage it would have been a shame not to..I was just in a hurry to get it back together..I watched it after I uploaded it and I almost deleted it..The capacitors are all good..They do look like they blew but thats actually just glue beads that they ran from the top to the bottom to secure them..

  • @purp13 I buttoned it all up last night and its running great..I ran my temp gun over it and the chips even with the artic silver are running at 165F..You know a good place there to piggy back a CPU fan? I need to find a spot to plug in a little 12v fan..Yeah I guess I do apologize to much..If you look at my other videos you can see I really don't need to..LMAO..Kidding...
