Westinghouse Digital Electronics LCD TV Model w32701

I have sound but no video. I can change the channels. When i turn the TV on, It flashes blue in the upper left hand side of tv. This flash is very brief.. less than a second probably. I suspect the power convert board. I think that is what you call it. Had a tv fellow look at it, and he said he tried a new power convert board, but it didnt help. I opened the tv today, and I feel the board has never been disturbed. What do you feel is the most likely problem. The power convert board, or the little light , like florsecent lamps. but much smaller. My model has 7 of them. Thanks for any advice you can offer. Pete Tate

    I can't see the picture, unless I turn off lights and make it dark in room. Then if I shine a light on the screen, it appears I can see some of the picture faintly in the background. I have been told that this problem could also be the main board. I can't seem to see the picture in regular lightning. From what I can deduct, it is either the inverter board, main board, or backlight panel. What would be your best guess? Thanks Dufay Tate

    My Westinghouse has the same problem, I had the inverter board changed and that did not fix it, I really didn't feel like going through the cost or hassle of fixing it at this point, so I went out and bought a Sony. When I went to buy my new t.v. the sales man said he has boxes of broken Westinghouses just like mine in the back room (JUNK!)

    I have sound but ** video. I can change the channels. When i turn the TV on, It flashes blue on the entire screen then goes black. This flash is very brief.. less than a second. Then after leaving it undisturbed for a week or so, it will come on and work just fine for about a week or so. Then the problems starts all over again.

I had the same problem..."No video but the Sound/audio was working fine." This is my solution.

Dissamble Procedures:
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.

Soldering Solutions.
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.

    Thank you for the hint. My W32701 went black recently I could fix it following yours advice (L168 was burned out). I made up my own inductance with ferrite bedfound in tv cable splitter. I wound about 10 turns of wire gage#24-26 and soldered as a hanging inductor (place permitted). My TV screenis back from the death. Valeri

Ussualy when the backlight is the problem you can see picture, try, turn it on and see if you can see picture, even if the backlight is off, you can see picture , if yes the inverter board or the power supply are the problem. but unfortunately could be the backlight neon lamps too, if is that the case it will be expensive to repair . There are some companies who can repair those panels but are no cheap. please let me know . thanks

Have a westinghouse lcd tv 50inch model ew50t5kw and would like to know before changing any parts or boards what causes a blue screen no sound or picture

  1. Frank: Verizon. com says try this: Change your VCR's Channel to 3 or 4. Most blue screen issues are caused by the VCR not being set to Channel 3 or 4. If changing the VCR's channel (using the channel buttons on the VCR or from the VCR remote control) did not change your TV screen, go to step 2.
  2. Make sure your TV is not in Video mode. There are three possible ways to change your TV's mode using your TV remote control: 1) Press a Mode button, toggle through the options and select TV, 2) Press a Video button to change your TV's mode from Video to TV or 3) Press Menu, locate Mode or Audio/Video setup and select TV from one of the options. If you are not sure how to change your TV's mode, see your TV's user guide for more information.
  3. Check to make sure your set-top box is plugged in and turned on.
  4. Check to see if other TVs (connected to different outlets) have a blue screen. If they do, contact the Verizon Fiber Solutions Center.

I got a WESTINGHOUSE that powers on and has a great picture but goes black in about ten minutes still has sound!! i can hit the source button a few times then picture comes back on then same thing all over...

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

Westinghouse lcd w32701

This sounds like bad inverter board.
Every time LCD goes from Standby to ON state - Inverter Board resets it’s self for approx. ~1 sec, during which time you should see blue screen.
Problem is that board detects problem with voltage/current on one of the seven transformers and shuts down automatically...
As to the costs:
- BestBuy repair service approx.. $600.00
- Buy new Inverter Board & repair LCD your self approx. $200.00
- Another option is to repair Inverter Board, but parts are sometimes hard to get...
Now for the DON"T TRY THIS AT HOME or AT YOUR OWN RISK solution:
-The cheapest method is to bypass protection circuit, by transferring good signal from working transformer (using 10nF/250V capacitor) to detection circuit at the faulty transformer.
Then watch movies on your LCD unlit BAD transformer totally BURNS-OUT.
This will be obvious by dark stripe about 1"-2" tall across your display.
Hopefully the only damage will be to the transformer and not CCFL (light behind your LCD), but when you are faced with a choice of using it for a while longer or throwing your LCD to garbage right now... to me this choice was simple.
Good LUCK.

No picture on Westinghouse W32701 LCD Model

Screen goes black, sound unaffected. Can be remedied by turning off and immediately back on, but it will do it again and again and again.
