hello, usually if your panny is blinking it means theres trouble with your power supply but depending on the number of blinks cuased by a fualty or shorted internal board and this will cuase your tv to go into shutdown mode, it depends on your model number and year it was made.
your best bet is to have a qualified service tech give you a estimate for the repair needed. as long as your screen is okay it will be easy for the service tech to locate and fix your trouble

panasonic blinking codes can pin point the troubled internal part, these blinking fualts are cuase by internal boards with malfunctioning circuts info below for 10th gen 2007 2008 plasma model service

12 Blinks SOS:
On the A board, transistor Q2301 monitors the Sound 15V line and the operation of the audio power amplifier IC2301. If the audio output circuit, IC2301, or the 15V lines develops a short to ground, transistor Q2301 goes into conduction and applies a high to pin 118 of the MPU, IC1100, triggering a SOS condition. The power LED blinks 12 times.
12 Blinks SOS: We have also discovered that 12 blinks of the power LED may also be caused by a defective SS board. To determine the source of the shutdown, disconnect the connector D5 and connect the unit to the AC source. If the panel turns on and the LEDs of the SS and SC boards stay on, the problem is on the A board. If the panel does not stay on, the problem is likely to be the SS board.

hope this helps

I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.

How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

If the power light blinks slowly,

you've tried to turn on the TV during

the lamp cooldown cycle. Wait

approximately 30 seconds, and the TV
will turn on automatically.

If light blinks, pauses for about a

minute, and blinks again: the lamp is

trying to turn on (TV will turn on

when successful). If TV doesn't turn

on and sequence continues, the lamp also
needs to be replaced.

To order lamp call 1-800-338-0376.

Have your TV serial number

and lamp type available (you'll

find this information on the

sticker that's on the right side of
the TV).
