Hi and welcome to FixYa,

Almost always, your described problem indicates a hardware fault and that the unit has kicked into auto-protect mode. Pls determine if there are any flashing lights. If yes do note the sequence/number of flashes/blinks. You may want to try and unplug for an extended period to revert unit back to factory default. If that would not be corrective, then the unit has to be opened for diagnosis and voltage measurements. Familiarity with electronic components & circuitry, use of a DVM and a soldering iron as well as access to a service manual and/or a schematic diagram would be required. Should you feel uncomfortable working with high voltage and performing a DIY (do-it-yourself), perhaps your best bet would be to seek the services of a qualified professional.

Should you venture DIY, pls post back the chassis number. Good luck and thank you for using FixYa.

Pioneer Plasma TV-PDP-4270HD won't turn on. TV


Try this! There should be a power button on the bottom of the panel that has to be depressed for the television to power on. It is the main power supply button and without it there is no power going into the TV.

My TV does not power up when the power button is pressed.


It's sounds like your lamp or backlight has went out, I suggest reading your manual for service info and look online for a local repair shop.

Tv would not come on..sound then came on.. 1 hr later picture


That sounds like a faulty inverter board.

The inverter board is the high voltage board that supplies power to the back light lamps.

The inverter must be tested and eventually replaced.

Power button Flashes


For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
