Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

SOURCE: 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.

SOURCE: 42" LG Plasma tv, no picture - black screen, but have sound.

Most a likely a problem with your Y-Sustain board which will then not drive the screen giving a black picture. The fuse on the board may be open circuit & need replaced but most likely you will need to have the sustain board replaced.

SOURCE: I have a Westinghouse TV , when turned on the

I just fixed the same model and with your symptom. What it appears to be is the main module is locking up just after the Logo goes away. All you can do is unplug and try again and all you will get is the logo for 5 seconds and then black screen, no sound and led stays lit. Cannot turn off or on. The power supply is actually working fine, it's the main module that has died. This module is no longer available, the part number was W470PROLX68. What i did to restore operation on this unit was to insert 3 volts into the plug going to the master inverter board and then plugged the tv AC cord in. The set showed the logo and then it started working. I removed the 3 volts and it has worked every time since then.
Here is what you should try to do: First take two AA batteries and solder them in series and attach two short wires so you can use it as a power source. Now you have a 3 volts power supply. Next Remove the stand first before removing the back cover. Looking at the back of the unit you will see the power supply and the main circuit boards in the middle (under metal shields) and two boards on each side. These are partially covered with a metal shield, the one on the left side is the master inverter, the one on the right is the slave inv. They both have a plug and wires going to them from the power supply, but the one to the master will have two extra wires. I believe the colors are purple and blue, and they are separated with an empty hole (unused part of the plug). The wire on the end is where you will hook up the positive lead of your battery pack. The negative lead simply goes to the metal shield. With these hooked up plug the tv into the ac and give it a couple seconds and hopfully you will see the tv come on. If it does then disconnect the battery pack and try it without it. good luck.

SOURCE: Westinghouse SK26H240S - Sound works but no picture?

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.

I have a Westinghouse VR-4085DF TV, every now and then it works fine, but most of the time I have NO picture, but we can hear the sound no problem. What is wrong? Can it be fixed?


Hi!

It can be the main board or the t-con board that is defect. This is only if you have a good power supply and the backlight is good too. When you have no image, just tap on the screen ( Not to hard ) with your finger tips, to see if you can see the backlight. If not, the backlight or backlight circuit is defect, if you have light when you tap, it's the rest i told you before. Good luck.

Codes listed in my manual for White Westinghouse are 0169 or 0003 or 0014 or 0043. Are yousure though there isn't a flip down panel somewhere which gives you the option to access "enter"

Hello,
Make sure you have your resolution set to 1680 x 1050 as this is the native supported screen size for this LCD. Also check your graphic card's overscan or manual adjustment settings. They might be manually set to offset the screen picture.
Hope this helps,
Chris
