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.

Panasonic TX-L42E5B blinks 3 times which board is faulty


When an abnormality has occurred to the unit, the protection circuits operate and set the unit to stand by mode. At this
time the defective block can be identified by the number of blinks of the Power LED on the front panel of the unit.

Fault maybe on the A board 3.3V SOS give me your email & i send you the full timing chart.

Panasonic TX-L42S10B has power but won't turn on


ok, this may be a silly question but when you turn it on and it starts flashing red, have you tried pressing the stand-by button on the remote. if a tv has been put on stand-by by the remote, and is then switched off by the set, when the set is turned back on it is still in stand-by mode and you need to press the stand-by button on the remote.
other than that I don't know.

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.

Set up new tv - doesn't work


Warranty time. The TV most likely went into protection mode because a part went bad inside.
I would take it back to the store and exchange it for a new one. 90 day warranty policy.
Have them test the new one to make sure it works so you don't have to waste another trip.
Good Luck
