Panasonic plasma TV will not turn on. Power LED at bottom of TV flashes 10 times periodically. TV rebooted, problem still exists.

Bulged Cap issue is to do with power sub-system and generally more in the LCD/LED tv not Plasma.

Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.

When the SUB5V or MAIN9V/SUB9V, short or over-voltage 15V short condition occurs, the TV shuts down and the power LED blinks 10 times.

Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.

But need to measure the connection SC2, if it short, it will be the SC board.

The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

On Panasonic 32LX TVs this is a known fault, repairable by a firmware upgrade. John Lewis in the UK sent out an engineer under their free 5 yr TV guarantee and completed the firmware upgrade for me. The only other store to compare with them for price and service is Richer Sounds but I believe you now have to buy the warranty for 10% of the purchase price. This problem will persist unless the upgrade is completed. For those of you in the UK, I would insist the seller repairs the problem under the Sale of Goods and Services Act as the TV is not fit for purpose without the upgrade.

Either a bad power supply or a bad processor board.
A Good Service Shop should know what the 10 blinks are indicating.
May be a repair cost between $200 and 400 dollars.
Be prepared -

If this is NOT projection, then the power supply is burnt out. If it is projection, then either high voltage transformer, flyback, or power supply is at fault

CHANGE P.A BOARD. THIS BOARD IS FOR TUNNER VOLTAGE..IF THIS BOARD IS BAD, THE LED FLASH 10 TIMES IN RED AND THE TV NO TURN ON.
