Having problems with your Flat Panel Televisions ?

My JVC LT-47GZ78 will not turn on. When I press the remote power or the main power switch on the set button the blue LCD light on the front of the TV lights and then starts to blink, the TV does no come on. Also there is a cliccking noise coming from behind the set. I'm in a country with 220v power supply.



Answers :

The blinking indicates that the protection system of the power board from the tv has detected a short on one of its outputs and has cut the power to it to prevent further damage - the clicking is made by the main power relay being disengaged, repeatedly, by the protection.\012\012\012
You should count the blinks - it's an indicator of what might be faulty. If the blinking is continuous then the problem is either in the control processor or the power source itself. To find out which and replace the appropriate board the tv will have to be opened and inspected.If you;re lucky it will be just the electrolytic capacitors on the power board. This is how you replace them

If there's more then you will have to check the voltages on the power board to find out what elsehas failed . If you can't do that then it's time to call a repairman.

When I hit the power button on my Toshiba 36AFX61 tv, or when I hit the power button on the tv's remote control, the tv's power switch button LED comes on but I get no picture or sound. And, the power button LED starts to blink after about 4 or 5 seconds. Also, at the time power is applied to the TV, I can hear extra relay contacts clicking that normally cannot be heard when the tv powers up correctly.

It started with the convergence going haywire, not fixed by restoring factory default or advanced adjusting of convergence. I turned the set off and unplugged it. The next morning it would not come on - only the green light flashing. Coincidentally (???) the cable box also would not even power on - had to be replaced.

My Sharp Aquos LC-60LE847U lcd TV has some kind of controller issues. At times when we turn the set on using the remote, the indicator light will light but the TV never has sound or picture.

My kdl55nx810 screen is blinking. While watching TV, the screen will go black for about 2 seconds, then come back on. It appears to happen intermittenly, every 15, 30, or 60 seconds.
