SOURCE: westinghouse LTV30w2 has blank screen and audio

What you have is a darfon V144 board (junk). it's a simple fix if you know how to use some basic tools and a soldering iron. Get an led (i used digikey's PN: L10041-ND) and solder it from pin 10 to pin 16 on the OZ960 chip on the inverter board. If you need the chip layout type "OZ960 pdf" in google. Hope this helps.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Thats usually an inverter board issue. Replacing the inverter should solve the issue in most cases. You can get the replacement inverter board from www.tvcircuitboards.com

Monitor comes on, I can see everything perfect then goes black


"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

Westinghouse LCD picture goes out after about 10 minutes


Check for swollen capacitors in the power supply. They should be flat on the top, not domed.

Westinghouse LCM22W2 shows a display then turns off after half a second


I have the same problem and have traced it down to a potential power supply issue.  I bought mine at Best Buy in '06 and was told today that they will test the power supply for free.  It may range from $50.00 to $100.00 depending on where you can get it.  This does not include labor for those not qualified to work with electronics.  Hope this helps you.
