1994 Toshiba CF26C30 , 26 inch TV. Intermittent power up. Part 8, Will it Werk?

Will it werk??

Disclaimer. TV's like this contain hazardous voltages and CRT's are under a high vacuum and have an implosion risk. I'm not responsible if you hurt yourself or the TV. I'm making the videos for entertainment only. I hope you are sufficiently entertained. If you have questiones about fixing your TV, then please take it to a qualified service person if they still exist. I admit that I am teaching myself how to repair this thing as the videos progress. Maybe I will achieve Yahtsee, or maybe not!

I would conjecture to say that, should the need arise, you can probably get replacement parts, such as ICs, for your television set. I had to get a replacement voltage regulator IC for my old 1984 Sears TV, and had no problem finding a new one at greatplainselectronics (dot) com.

You have impressive and enviable powers of deductive reasoning in addressing this problem; you appear to think like an engineer.

@HardKnocks60 Thanks! That's great because I really want to fix this. The Picture tube is still good and bright.

The resolution is very good. Much better than most LCD's I've seen in analog mode.

Have analog service at the house.

Part 10 wil have me get to brass tacks. I've been working up slow for a reason. I don;t want people to take their sets apart and start working on them and get injured. I figgure if someone doesn't have the patience to watch the videos, they won't fix the set!

What a pisser....to spend all that time on it, and still not have it work....very frustrating, I'm sure. Those intermittent problems are always the worst.

@mznxb9872 no worries...i aint done yet

[Lockemeister]

@mznxb9872 ain't is a contraction of aint not and is perfectly good english!

@Lockemeister get out your DVOM turn the set on it's face, leave it switched on and start checking voltages, then track back in the circuit till you don't find the voltage you need and inspect suspect component. I've had to do this very thing with my crt projector and that has WAY more parts than this tv, and also a healthy 48kv three lead flyback, scary high voltages going to those 3 crt's!

[Lockemeister]

@grassulo i was hoping you made some videos since you had some inspirational message, but I guess you ain't got none.

[Lockemeister]

@grassulo I can check some volatages but not all. the board is not exposed well and the leads dressing is not sufficient long enough to allow board removal while also powering up. Measuing voltages if possible was my next step. thanks for the great comment.

@umajunkcollector I did like the lab rat on that show. The girl assistant was cute. youknowwhatimean?

[Lockemeister]

@umajunkcollector I'm glad I'm entertaining somebody!

hoooraaay for hollywood!
