Question about Televison & Video
Ok so watching tv, picture went but got sound, have unplugged for hours and still no go??
Posted by Anonymous on
On both of these, most likely the power supply board needs to be replaced. The backlighting could have gone out too, but that happens less often.
If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!
If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok

It's either the backlight lamp or backlight inverter is busted
due to a power failure or fluctuation. Here's how to determine which is which:

Your filter capacitors have popped due to diodes shorting, P-channel FETs shorting from gate-to-drain. Pull-up resistors have changed value and as a result your capacitors have peaked (popped)....so now the tv is in protection mode to prevent further damage to your tv. Take it to your local shop for servicing, or take it back if its under warranty......

SOURCE: 32" flat screen that went 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.
Please post back what you find.
