Question about Westinghouse SK-26H520S 26 in. LCD HDTV

1 Answer

Television suddenly turns black

The television plays normally, but suddenly the screen goes black. Other times, the screen turns to hundreds of vertical stripes of all colors. When it goes black or striped, the remote works but it has a 5-second or longer delay. The problem is temporarily fixed by turning off the power and restarting, but the problem persists. I notice no patterns with the problem. It seems quite random.

SOURCE: black screen

I fixed it! It's the power supply board.

The Westinghouse LCM 22w2 has bad capacitors on the yellow power supply board. This is a common problem plaguing motherboards and LCD flatpanels that use capacitors from Taiwan. If you know how to solder, or know somebody that can, it's actually a pretty easy fix. Take out the yellow circuit board on the inside, write down the specifications for each of the capacitors (the cylindrical things) go to the electronics supply store and get the replacement capacitors. You can go over the voltage specification (not under), but keep the capacitance value matching. Replace one at a time. Go to www.badcaps.net for advice, tutorials and training on doing this. *You really should replace all the capacitors*, but the very large one next to the power plug I did leave on the board because I couldn't find a match. To my delight, the problem went away and it was working as new!

I saved a ton of money fixing this, it's definitely worth learning how to solder to do this.

Rainbow line will come across screen and then goes blank. This is an intermittent problem. Normally if I turn it off and back on, it works. Now it does not.


try resoldering the vertical output IC, the IC runs at a hot temperature and this can cause the Pins to have cracked solder.

LG 47" LCD FLAT SCREEN


IF IT WASNT DIGITAL HD I WOULD HAVE SUSPECTED HIGH VOLTAGE POWER SUPPLY BUT THAT DOES NOT EXIST HERE.
Well, not completely true; the fluorescent backlight is still a high voltage device, even if only hundreds of volts instead of kilovolts, and either the lamp(s) or the power supply for it (them) is causing the dropout of your picture. When it does it next time, look at the screen from various angles, I think you will see that video content is still there.

Hitachi 51g500 screen gone black


Yes worth repairing but not a crt problem. the crt's are powered by a high voltage transformer and sometimes it's caps that goes bad and in turn knocks out the crt's. but they are ok, it's in the high voltage line.
