• 10515 Answers SOURCE: Hi, To begin with, i would like to inform you that this is an internal failure.A reset / restore would not resolve this problem. Till the time you could use like ( as you mention it normalizes after few minutes ), it would be fine.
The problem could deteriorate within a day, might take weeks or even months. This is a problem with either power supply board or might be panel. The repair cost would be high as compared to the cost of the product. If you have electronics repair experience, could read schematics and would be able to keep all precautions, i could tell you where to tell you where you could buy a service manual and would be able to guide you to fix this.
Let me know,if needed further assistance. Hope i helped you. Thanks for using ' Fixya ' and have a nice day!!

Please try and read the link below to get more understanding. First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. If not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

Or, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series. Posted on May 18, 2011. • Find the programing code for the device's manufacturer in the manual.
• Turn on the device you are programming the URC 3220 remote to control. • Press the 'TV' 'DVD/VCR' or 'CBL/SAT' button on the remote. • Press and hold the 'SET' button until the red LED blinks two times. • Release the 'SET' button and type the manufacturer's code.
