The power light is just blinking red on my panasonic 1080i hdtv. cant even switch it off using the power button. picture and sound come on for about a second when the tv is switched on after power cord...


The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

The unit will not power on. It blinks twice then powers off. Each time I power it on, it blinks twice then powers off. No video, no sound.


B+ over current fault in the power supply circuit, probably a few bad resistors and some switching regulators. Call your local shop for immediate service, its a rear projection TV so it shouldn't cost too much to service this kind of fault. Here's a little trade secret for you, one good way of getting more years of use from your TV is by using a surge suppressor opposed to a surge protector. A good one will start at around $69.00 from BestBuy or Wallmart.
Here's a little basic knowledge on what a surge suppressor is and what it does : Click Here and here's how some will look Click Here.
After you get your TV serviced, be sure to use a good quality surge-suppressor to fully protect your TV from violent AC spikes. Using one will and years of life too your TV :-)

The tv will instantly shut off after its powered on. I did a self check by holding the menu and input buttons for 5 seconds and the green power light in front blinked twice then paused, and blinked twice...


this is error 22. which is a short curcit protection error. the first suspects in this case is the convergence ic (stks) these are supplied by 24 and -24 volt lines. these short and shut the set down.

Power will not come on even after system reset. Pushed reset and LED flashes then after it stops flashing TV will still not turn on.


do self check: when it shuts off and power light goes off:

On front of set press and hold both menu and input (device) buttons for at least five seconds and release both buttons.

Power light will blink a two digit error code, like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code and I will assist you

Tv randomly shuts off


next time it shuts down and power light goes out--do the self check.

On front of set press and hold BOTH MENU AND INPUT BUTTONS FOR AT LEAST FIVE SECONDS AND RELEASE BOTH BUTTONS.

Power light (if an error is detected) will blink a two digit code.

Most common is 2 blinks, pause and 2 blinks---set if there is a error code will repeat it at least 5 times.

If you detect a error code, let me know and I will tell you what it means.

TV shut off while watching and won't come back on


It seems this is a self diagnostic function. the official sony codes are as follows

  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.
It sounds like you have a video input problem. Have you unhooked all inputs from the TV and tried to power it back on by itself? Hope this helps
