the only thing in common with modern day lcd televisions are the garbage components intentionally used in manufacturing to ensure premature failure and disposal.

Good evening sir...I have a SHARP TV with model number KDL40V2000. It's showing blurred images and the screen has horizontal marks whis is felt while rubbing the surface of the screen with the palm. Please what could be wrong?

Jimmy, just like you've asked us to send you questions, I did send you one but did not get a response. One of the 6 plastic connectors to the scan board is unglued and I don't know what to use to glue it back to the board without messing things up.

I have a dixon 31 inch, LED tv, model number:STY0632 , someone peeled off the serial number sticker , like you said in the video, the backlight is on, like when I switch on the TV, you can see the blue-black backlight is on, the audio plays fine, but there is no image, is this the T-con board that needs to be repllaced? Then at some point when the Tv gets hot, the image suddenly appears.

Advice please. I have ann old Sony Bravia and all the HDMI ports do not work. Should i replace the board?

I have a 55 inch Samsung UN55RU8000FXZA.

1) The standby light flashes momentarily when I try to turn on the TV but there is no picture/ sound/ or backlight.
2) The 3 electrolytic caps on The Power Supply Board at the top left ( near the o/p to the main Board) have 'domed' tops.
3) When I unplug the Main Board from the Power Supply Board the Backlight turns on.
4) The o/p connector of the Power Supply Board has ground at the pins at the ends & all others are 13Vdc.
5) The 13Vdc is present with the Main Board plugged in or not plugged in.
6) The Main Board does make a sound at turn on like a 'Flyback Transformer' (but only for a moment).

My first thought was that the Main Board has a short that is drawing down the Power Supply & keeping the Backlight from turning on. But the other possibility is that the Power Supply Board can't source the current to the Main Board.

7) Additionally, I disconnected the 3 output cables from the Main Board & the backlight is still not lit.

Have you any suggestions?
