SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

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.

SOURCE: Panasonic PT-60LCX64 does not power up

There could be a possible failure of the Ht circuit, check on your Ht Drive output trans, the LOT, any shorting in the HT capaciitors, short in the LT line. You will need to probe into the power side as there is a safety switch off. the microcontroller is working fine and hence trace carefully looking for damaged resistors, capacitors or transistors in the power side.

THE 10 flash code is for the power supply

The Seven flash code is for the SC pcb (ysus) it is best to change the SC, SU, SD pcbs as one can take one of the others out
and if you add a new SC and one of the others is faulty then you will have another dead SC pcb

Tv will not turn on--- flashing red led


I'm sorry, I don't have a solution, but I seem to be having a similar problem. When I turn my TV on, the green light comes on like it's powered up, but then the TV turns itself back off and the red LED light flashes. I can't do anything to turn it on or anything.
