Yeah, that Mitisubishi is huge. Probably not HD. But would still be awesome, even as just a learning experience. Electronics have changed as they modernise; inside it's probably chock full of discrete logic and analog circuitry for the video instead of the modern RCA which looks to have only a BGA packaged display processor which manages everything.haha, I've created a monster!
I was checking out my competition's ads and most specify models 2005 and newer. That would be a good idea I think. would prevent you from showing up to find you are dealining with a dinosaur like this 1/4 ton mitsubishi I just brought home.
I've touched a flyback before. It ****ing hurts. That was only a small portable B&W TV, probably less than 5kV. Some big screens can have 50kV supplies! And a rear-projection will probably use a triple flyback for the three tubes.Good thing You're in Texas, or I'd be over to "Help" you dispose of the leftovers Like I need more "supplies"
Success is a great teacher.............Please don't overlook the humble pie, and get careless with these high-voltage beasties.
I can't speak from experience because I haven't sold one yet, but my expectation is that the market for smaller TVs might not be what the market for big screens is. how much will it cost you in gas to go pick it up? if that cost is approaching £10 then not worth it in my book. also, what's your time worth (i.e. what's minimum wage) and how long will it take you to retrieve it and how long will it take you to fix it? it seems you may end up with more invested than you can get out of it. All that is assuming you are only in it for the $$ (or ££); it sounds like you have alot more experience than I do & the majority of what I'm getting out of this endeavor is experience.Okay well I got an offer to buy a 32" TV with broken LCD + remote control for £20. I think I can sell it for £30, or I could strip it for parts and sell each individually for maybe £100 total, but I might not sell all the bits. What to do......
The guy is like 2 miles from me. I'm just going to do it as an experiment; if it doesn't work out I'll only buy TVs with bad PSUs. I think £20 is a worthy investment to "test the waters."I can't speak from experience because I haven't sold one yet, but my expectation is that the market for smaller TVs might not be what the market for big screens is. how much will it cost you in gas to go pick it up? if that cost is approaching £10 then not worth it in my book. also, what's your time worth (i.e. what's minimum wage) and how long will it take you to retrieve it and how long will it take you to fix it? it seems you may end up with more invested than you can get out of it.

OK thanks!The shield is fairly important; it helps reduce external noise, and emissions by the receiver itself. (Sounds odd how a receiver could emit noise, but the PLL/oscillator does.)
Use a can of compressed air to blow out all the dust.
Do you have a scope?
Some tin foil might be good enoughOK thanks!
One more question; is the shield cover engineered a specific way out of a specific metal? Basically what I'm after is, can I just slap any old piece of metal there and solder/glue it in place, or should I be looking for an OEM replacement?
Yes I have a scope
Ok, will do. later on this evening when i get home.Some tin foil might be good enough
If you have a scope get it to play some audio out of the speakers, then post the trace of the audio signal. No signal: burnt out power amplifier IC somewhere.
what about RCA? So far they account for 3 out the 5 TVs I have come across in my very short time as tv repair hobbyistOn Philips reliability in the past, betwean 1978 to 2002 they were great for making money from repairs, certainly kept me busy. The other sets i handled were Hitachi & Toshiba, no money there in repairs to reliable.
