Problem with Panasonic TC-32LX70 Television
Panasonic 32 inch LCD TV will not turn on-red light flashing6 Solutions
I have had my Panasonic 32inch LCD TV about 18months. It will not turn on with the remote or the power button on the TV. I have unplugged it from the wall and plugged it in again but no change. The red led light on the lower left hand corner of the set is flashing intermittently. I can turn on TV (Panasonic TC-32LX70) with neither the remote controler nor power button. I have to unplug power sauce and plug it again to turn on. This happens a couple times a week.

The number of flashes is an error code. Count the number of flash. It looks like one of the boards in your set is failing intermittently. Panasonic codes for a guide as a starting point. Exact board STILL has to be verified;
One Blink: One blink of the power LED indicates a problem in the inverter circuit located on the LCD panel. The inverter board is not to be repaired in the field. Therefore a replacement is required.
Three Blinks: 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.
Five, Seven, or Eight Blinks: The A board is responsible for five, seven or eight blinks of the power LED. The MAIN +3.3V, MAIN +5V, and MAIN +9V sources are all produced on the A board. The detection input pins of the MPU, IC1100, monitor for their presence.
Four or Six Blinks: The AP board is responsible for four or six blinks of the power LED. The DTV9V, and SUB_5V sources are produced on the AP board. The MPU IC1100 monitors for their presence when the unit is connected to AC Power. A short or open circuit on the A board may also be responsible for their absence.
Nine Blinks: Nine blinks of the power LED is due a short circuit in the audio output circuit (s) of the unit. The audio output circuit is located on the A board. Confirm the status of the speakers. If defective, perform a replacement. If ok, replace the A board.
Ten Blinks: Ten blinks of the power LED indicates a malfunction of IC4200, the frame converter. This IC resides on the A board. Therefore ten blinks of the power LED requires the replacement of the A board.

A friend of mine and I have that same model AND that same problem. It's not a permanent solution, but it prevents having to unplug it from the wall (pull furniture, pull plug, wait, plug back and more furniture...) It also prevents spending $$$ for the repair.
I hold the power button on the top of the set down for 5 seconds and then the tv responds. The problem goes away for a while and then comes back.

I checked on the Panasonic site and it appears that they have a firmware update that addresses this issue.
It requires you download the new firmware fire & copying to a formatted SD card. There are instructions there on the Panasonic site to guide you through the process.
I don't use SD cards, so I just ordered one and will try the FW update when the card arrives.

This is a known fault. John Lewis in the UK sent out an engineer under their 5 yr TV guarantee and completed the firmware upgrade for me. The only other store to compare with them for price and service is Richer Sounds but I believe you now have to buy the warranty for 10% of the purchase price. This problem will persist unless the upgrade is completed. For those of you in the UK, I would insist the seller repairs the problem under the Sale of Goods and Services Act as the TV is not fit for purpose without the upgrade. You have 6 yrs (not a year or 6 months) to claim under this Act.

Do you know where you can get this SD card, how much it costs, and if it actually works?
