These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/ Blinking codes details to many popular brand TVs are given.

hi, if your tv has totally black screen the cause is either the inverter board get busted or the back light need replacement. if their is a white screen display but no picture, you must check the t-con board for screen panel display which have defective or burnt component parts .

That sound a lot like a backlight issue that in a lot of cases is due to poor capacitors on the power supply. The power supply also usually contains the high voltage generators that supply the backlight to the display. Search for that symptom on the internet with your model and brand in the search bar and you will find that a lot of people have the same problem. Those people that are technical often fix it by removing the supply and replacing the capacitors with those from DigiKey or Mouser Electronics. These new parts are not the very low grade Chinese parts that were made to a build the part. I have repaired many computer displays in the very same way- in fact the hardest part of the job is figuring out how to open it up. The capacitors I speak of are the larger Electrolytic types that are showing a puffed condition or are venting. See this answer as it has pictures.http://www.fixya.com/support/t8813525-turned_set_indicator

If all the other inputs are working and there are no issues in the signal strength and quality , the fault of the failure of the HDMI can be related to an interface within the TV.This can be related to a logic gate failure and ONLY a logic test will prove the failed section that connected with the processor.

The tv power supply board it is shorted and dead.That the board where the tv power a/c cord plug into it.Tries websites like Shojimmy.com,Ebay.com to buy a whole new refurbish tv power supply board for the replacement.

Do you have sound?
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.
