I would believe this to be a problem with the lvds cable that goes from your logic board to the main board. If your tv does not have a logic board, then it would have to be incorporated into the main board. A lot of times the connection gets loose on the main to logic board. If you reseat it, it may fix itself. If nothing else, you can pick up a logic board on ebay for around 25 dollars with shipping. It is usually very easy to replace. Most of the time, it's hidden behind the A board known as the Main board. It would probably take less than an hour to put in for someone not familar with the internals of a tv. Just MAKE SURE the tv is NOT plugged into the AC line. Regards, Joe Van Buren

These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs.

Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.

Could be a bad remote, that button isn't responding

I had the same problem with my Viera. if you disconnect the power and ribbon cable from the YSUS board (check youtube for how), the light led will blink 6 times, indicating the YSUS is bad. Check ebay for TNPA5175 board (about $115-160). The pop is one of the DG402RP chips burnout. These are about $4, but only available from China. If you can wait a month for delivery, you can solder the new one to replace the bad one. You may want to purchase several in case more are bad or it happens again.

That probably won't work. You'll have that problem until you get a new TV.

I would say that's pretty much had it ,if there's smoke coming from the back something has burnt out I would take it to a TV specialist to see if it can be repaired Nick
