How to turn my TV back on?

I have a Digistar 40 inch LCD TV that i moved to a different room. When i plugged it in a day later, all i got is a flashing blue power light near the remote sensor. Pushing the power button again does nothing...unplugging the TV and plugging it back in does nothing either...The tv worked great prior to the move...what can i do??

SOURCE: LCD TV WONT POWER ON

A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.

First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.

If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.

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.

Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.

Sorry, I am not famillar with your model, however most flat panel problems with start up can be traced to the power supply as the capacitors can fail due to the high operating temperatures. An electrical surge can also come in through the Cable and or antenna connection as well.
