Having problems with your Flat Panel Televisions ?

I have a Samsung LN46A530 46" LCD TV. Lost my backlight and wondering if the two wire connectors feeding the R and L inverters is where I would meter for power, and if not what are these for ? Or is it the ribbon cable on the top left (it's pin ids are 1. 12v_cold, 2.FB, 3.FB, 4.GND, 5.GND, 6.LD, 7.LD). Would this TV use 12 V to power the inverters ??. The inverter enable is on (5V), so I assume it is either the pwr supply or the master inverter.

I have a 22ins lcd tv/dvd combo when yhe power lead is attached the power light flashes very dimly there is no sound or picture. when i disconnect the inverter board both dvd and sound work and the power light is normal . obviously there is no picture at this stage as i,ve disconnected the inverter , would it be a correct assuption that the inverter is faulty ?


It is possible but a voltage check of the power supply will tell if it is bad or something downstream is pulling voltage down, power light going dim means something is really loading the supply down. ... Flat Panel Televisions

Vizio GV47L...when i turn on the tv, the screen stays black. The vizio light turns white and it makes the click noise like normal but after a minute of it doing nothing the light turns back to amber. I can turn it on and off using my remote. I read other problems where people had to unplug there tv to turn it off. Mine will turn off. Would the problem be the power supply or the motherboard.

When I first started noticing problems I would turn the TV on and I would hear the power-up sound, the backlight would come on and then the red LED would flash a few times then the backlight would go off and it would repeat (power-up sound---backlight on---LED flash---backlight off). It would do this several times. Sometimes I would be able to get picture if I hit the source button on the side of the TV when the backlight first came

Power Surge After house power went out and came on 20 seconds later, my Pioneer would not power back up. It has two LEDs - the blue "on" LED flashes 12 times on, pauses, and repeats the sequence over and over. I tried powering down from the switch and even removing AC power entirely for a couple minutes. The best it would do is to go thru it's normal power up sequence, show a "starting up - please wait" screen for a couple minutes, and then shutting back down with the blue LED flashing.
