Hello everyone. I have a problem with an old Samsung LCD TV (LE32M86), maybe there are some good technicians here that can figure out what's wrong. Please note that I don't know much about electrical stuff and components, I'm just "translating" what a friend of mine says.
So, the problem started about a month ago when I noticed that it takes longer to power up than usual. It was like 2-3 minutes from the moment I pressed the power button on the remote till the TV was actually on. I didn't think much about it back then, but a few days ago the "delay" was about 20 minutes! The power led blinks, like it should, the backlight goes on, but the screen stays black, then the backlight switches off, and so on, till it actually manages to start. There is no problem with colors, sound, etc., so I thought it's some power issue. So I sent the tv to a friend of mine that works with electrical stuff, tv's, etc. He tested the power source and found nothing wrong with it, but he did notice that from the moment he tried to start the tv, his testing device showed 12V, then 2V, then 12 and so on, so he said there must be some component that drains a lot of power and the tv cannot start. He changed some capacitors here and there that were a little damaged, but that didn't fix the issue. Another thing he noticed is that a component heats up like crazy, in fact the only thing that heats up much more than it should. I looked it up and it's a Sigmatel SGTV5810C, the audio IC judging from what I found online. Could this be the problem?!
One more thing. After the tv starts, if I shut it down and start it up again, it starts normally, like it should. Only if I leave it off for more than 30 minutes it starts so slow.
Please, don't start with "buy a new tv" or stuff like this, if you can help in any way, then thank you, if not then please don't reply.
