Question about Westinghouse VR-6025Z 60" LCD TV 1920x1080, 120 Hz, HDTV
Tv won't power on. It has power to it but will not turn on. No normal noise of when you do turn the TV on. No video or audio. The power board has no visible bulging capacitors. Fuse tests good on ohm meter.
Hi i'd check the voltages on the connector on the power board, it sounds like you have 5v standby, i'd check for 12v and 24v or look for a tv tech in your area

I had the same problem..."No video but the Sound/audio was working fine." This is my solution.
1. There are 4 different types of screws used. So, you can copy my technique. I used masking tape. Everytime I took out screw I taped it beside the hole.
2. You can pull the Video/Audio RCA box by plier, it is detachable.
3. You can pull also the antenna input box by plier.
4. When taking out the Inverter board, you have to flip the lcd upside-down. There are 4 screws at the four corners.
I soldered all 7 transformer's legs. 8 legs each transformer. I soldered also the 8 capacitors. Checked the 4 fuses.
Main Part of Solutions.
The problem was coming from the 2 surfaced mount inductors. That's why there was no supplied power (voltages) going to the inverter.
These 2 tiny inductors are labeled as L21 and L168 connecting the 12v supply and transfering the power to the inverter. IMAGINE THESE 2 TINY PIECES CAN DISABLE YOU VIDEO? That's why even if you are going to buy a new Inverter board it will not solve the problem. Because the 2 inductors are not connected fully (cold solder) although by naked eye they seems fine. Solution resolder them both.
I used 30w Radioshack soldering Iron. Don't use the 40w because the tip is thick and can damage the neighboring electronic parts. Use a tooth-pick for pressing the inductor while resoldering both ends. I used an over-head magnifying glass while soldering these 2 inductors because the size is HALF GRAIN OF RICE, I am talking a very very tiny piece.
Warning: Over heating can damage these inductors. Just in case you damage one of them. You can find a replacemen on a Dell desktop P4 motherboard. Can be found near the 4 pins cpu power (2 black and 2 yellow) for 12v.
It's been almost 3 days now my Westinghouse LCD TV still working fine.

I have a Westinghouse Mod. SK-19H210s that is 16 months old. It would not turn on. Upon investigationg the problem I discovered bad capacitors on the power board. (2200uf and 1000uf). I replaced the components and the TV works great, you can purchase a new power board.

I just fixed a neighbor's by replacing the 2200MFD capacitor on the power supply board. Thanks for the help, worked great. If you replace it got for a 16V instead of the 10V and hopefully it won't fail that way again.
Just be careful and take notes when you're digging into it. And mark exactly where the card cage is before taking it loose.

Are you sure you got the polarity right when you installed the capacitor? On the one I fixed the negative lead went to the outside of the circuit board but check the diagram underneath.
