iN LCD'S YOU HAVE A backlight When they flicker that means its time for a change, I would highly recommend you have the inverter and back light checked. $45 bucks for your examination and $125 for the backlight, $150 in all and its a working TV again.

If you do this yourself let me caution you if your not a expert I would keep my hands our of the cabinet and take it in and pay the piper as if you put your hands on the wrong thing you will be giving yourself a nice jult.

Thanks and please do press the accept button for my efforts.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Hello,


The flickering is caused by a power supply about to died and now with the picture blank that shows it has a total failure. The most common problem with monitor power supplies are parts called capacitors, they overheat in the case and short out. If you can solder then you should be able to do the repair yourself. We have pictures posted on our web site at:
www.ccl-la.com/capacitors.htm that will give you an idea of what to look for and what you will need to replace. We do many repairs on LCD computer monitors and yous unit is basically just a big monitor with a tuner attached. If you have additional questions you can contact us at: [email protected] If you don't want to do the repair yourself we do offer a repair service for your unit for $45 plus return shipping.

I hope this helps you.

Do you still have sound on the set?

  • Anonymous Jan 17, 2010

    Sorry. I was asking for a clarification thats all. If you still have sound we can narrow down the problem to the t-con board or the backlight inverter and then I can provide you a simple diagnostic which can confirm which one it is.

    Sai.

It has power but no sound and no picture. TV turns on and power button flashes about 12 times and then stays blue.

Hi Dustin,
If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.
