Dave,

Im having the same problem. I've had my tv for 1 yr 6 months. How long have you had your tv for? I do the exact same thing you do to fix the problem. Obviously its not a permanent solution. If you find the answer to the problem please let me know. I'm holding out as much as i can before i take it to a repair place and pay the rediculous prices.

Please make sure your connectors are in the proper place.

The HDMI inputs on the rear of the TV are optimized for use with Audio/Video devices, Blu-ray Disc Player, DVD Recorder, etc.
The front or side HDMI inputs only are designated for PC. To use the TV as a PC monitor, advise customers to use only front or side HDMI inputs.

Any antenna with a 75 Ohm impedance RF coax in or out, or a 50 year old set of rabbit ears with tin foil and a 300 - 75 Ohm transformer (adapter) will work. There are many new ones to chose from and they will go right in line with the cable from the wall (basic) or your converter box, or you can splice it in with an impedance matching splitter. The powered ones with active filters are nice. You can find them in the RECYCLE bins up and down the street this week

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
