I had this problem with these tv`s. The problem actually lies with the power supply inside the unit. Some of the units i`ve seen have 2 blown capacitors on the power supply (C7 and C6) replacing these works. On others, the capacitors as well as a few transistors (Q8 - Q1) are blown. But on all the sets i have seen with this problem, changing the above components restores full functionality to the system.

The simplest problem would be the failure of the backlight.

In case you don't already know it, there is one, and they may or may not last forever.
Also, there is an extra power supply to produce the high voltage the lamp needs to fire that may have failed.

Sometimes, you can look at the screen from an angle to see if there is any sign of movement.
If you can see program material causing a change in the faint image, then you can be pretty sure it is one of the two problems mentioned.

I have a line in the middle of my screen.what can I replace to fix this?


To be honest, you're not going to like this but... the simple answer is to replace the TV. You've got a short on the circuit board that controls the LCD display. You could replace the board, but for a 20" TV it's actually cheaper to buy a whole new TV. Hope it's under warranty!

Check to see if you have 24vdc at the inverter board fuse as shown in the picture, the problem can be the inverter board or power supply board.

I need a remote code for a westinghouse LCD TV, model LTV-20v4, with a MOTOROLA remote control


Hello, if the remote is a universal remote you will most likely need to input the Sony codes. Another option is to purchase an original remote at parts@wde.com, the price for the remote is $15 plus $5 shipping and handling.

I have sound but no picture a all on a Westinghouse LTV20v4. The menu does not come up.


Check for bad capacitors in the inverter board, it may have taken out the 8 transistors when the caps went open.
