Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

I have a 52" westinghouse


Ok you have a lot of things going on here. Your first thing with the lines can be your T-con board or your Signal board or the screen itself. The second thing black screen you would have to be more specific? Is your back light on and you have no image? If that's teh case then I would replace the T-con board or the Signal board. If by black screen you mean there is no light on the screen from the backlight inverter then your BAcklight inverter or the backlight itleft might be bad. and ontop of that you might have the problem that we started with also. You can get westinghouse parts from www.interliquidparts.com You have to order by part numbers so you have to get the number from the actual part of your TV.

Tv comes on then the screen goes black but can still here sound


This has to do with the voltages supplied to the backlight inverter. There with be 2-3 capacitors needed for the 24v rail which is NEEDED for the backlight inverter to work. Without the backlight inverter you will have no picture and still have sound.

If you are good with electronics you can open the set and replace those capacitors and your 24v rail will be restored. You will then have a picture and sound

My LCD HDTV screen keeps going black.


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.

32" flat screen Westinghouse TV


Hello, it sounds like you need to replace the inverter board on this unit. I would recommend opening the unit from the back cover, get the part # for the inverter board (long green board normally running accross the edge of the TV) and go to www.shopjimmy.com, they should have it in stock and if not you can try www.invertercentral.com, they should also have it.

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.
