My 32" Element tv has the red light come on when it is plugged in. It will no longer power on. When unplugged the screen will flash. I have the back of it off and have blown off all connection and the fuse seems to be in tact and the red light does not light when the fuse is out, but does when it is in.I have disconnected all wire harnesses and reversed them hoping maybe something just wasn't making a connection, but with no success. didn't know if the was anyway to get the tv to power on? Just looking for suggestions before trashing this set.it used to just come on after a while or when we would unplug and press power button, but doesn't any longer.
SOURCE: TV won't power on.
Open the back of the TV,and look at the can shaped items on the boards.If any of them have the tops,or bottoms bulged out,they need to be replaced.This should get it working again.I hope this helps.If you have any questions,please let me know.Thank You very much!

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.
