Re: Vizio vx42l reset button???

So I finally had the time to test the U33 chip and it doesn't give a reading at all. Any suggestions on where I can order a replacement?

Awesome! Thanks a million guys, I really appreciate the help. I've made plans for a friend to come over with a multi-meter to check the LDO regulator. I'll repost my results.

Oops, sorry guys didn't know about the pictures.. Definitely will remember that for next time.

I don't feel comfortable with soldering myself. I might call a few TV repair shops and get quotes. I know of one person that can solder and he wanted me to ask,

What values am I looking for when testing the U33 LDO regulator?

Yeah tell me about it!! haha Here are a couple pictures of the main board and the power board. I think I'm going to buy a new main board. Someone I know just had his main board recapped for $200 and that only lasted less than a year and he ended up replacing the main board ($250 installed) last week by a tv repair man. I have found this main board on ebay for $100 shipped so I guess it wouldn't be too bad of an investment seeing how I did get this tv for free.

Recently I was given a Vizio vx42l for free. When you plug it in, the Vizio light turns on. When you turn the tv on, the Vizio logo turns to white and the back lights turn on but no picture, no sound. Your unable to turn the TV off with the remote or the buttons on the side so I unplug it. Took off the back, and did not notice any bad caps or any indication that any of the boards are bad. I checked all fuses, one on the power board and 2 on the main board(?)

My question is, I've read about the reset button on the main board, but does it need to be plugged in when I press the reset...
