Re: polaroid tv capacitor identification

Some stuff came up and I had to stash the TV project for a while. I'm getting back into it tomorrow. So I should check the voltage on the rectifier? Exactly what am I looking for? Are most rectifiers of that type in a black box?

If I test some voltages at various places could you guys help me troubleshoot?

Re: polaroid tv capacitor identification

They might have but my neighbor is not an intellectual powerhouse. When I called the shop an old Asian lady answered the phone and wasn't very helpful. I thought she might have said it wasn't a capacitor problem but she could just as easily have said that just because I said there wasn't any visual problems. (Hard to communicate with her) She acted like she was mad that they chose not to fix it and she seemed aggravated with me because I was trying to fix it myself and take away her money or something. Basically, it seemed like she was purposefully...

Re: polaroid tv capacitor identification

Well, due to my ignorance and lack of forethought I have already pulled out the large capacitor and possibly damaged it in so doing due to me having to pull it off the glue it was in with some pliers. Surely it won't hurt to replace it, right?

Is there some way I could test the smaller caps on the "right" side with a multimeter that just measures voltage and resistance?

Also, should I just go ahead and replace the capacitors that I have mentioned or is it probably something else? It couldn't be the...

Re: polaroid tv capacitor identification

I received a Polaroid TBA-03211C flatscreen TV from my neighbor who was moving out. He said the TV wouldn't turn on and he took it to a local repair shop and they quoted him $400. That obviously wasn't worth it so he gave it to me (because I KNOW I can fix it for much less).

I am not an electronics expert but I am somewhat experienced in general electronics work. Basically, I wouldn't be able to design and/or troubleshoot a device on my own without some instruction but I can hold my own and learn quickly.

The power...
