You need to replace the blown capacitors on your PSB-power supply board. A soldering kit w/flux from harbor freight or radio shack and and about a dozen new Thru-hole caps about 2V higher than the ones your are pulling out.. Or if that isn't to your liking you can just buy a refurbed board on ebay shopjmmy or partsstore. You will need to remove the back panel and pull out the PSB disconnect a few wire harness and some ribbon cables and a few screws the board will pop right out. The board with be printed and say Power Supply with the REV number (part number) printed on it. That's the one you need to look for. If you want to replace the caps yourself you'll visibly see the blown caps they should be completely flat (X) top view no puffs or bulges. It's pretty simple to remove them and solder some new ones in.

SOURCE: Power light blinks 10 times

You have the same problem i have. My Tv just did the same thing 3 nights ago. I unplugged the set, and let it sit ofr about 6 hours, and then tried it again. It turned on and played, but repeated the problem after about 20 or 30 minutes. So far all my research has led me to believe that its a power supply issue. Problem is, there are 5 boards in the tv with seperate pwer supplies, and the 10 red flashes indicate that its all of them. :-(. Im shopping for a new TV, and It wont be a panasonic this time.

A red light blinking 10 times means that a video board has gone bad. Contact Panasonic to see if they will help you out.

SOURCE: TV clicked and went blank...no picture, no sound.

Most problems with TV not turning ON is a power supply related problem. The relay click are a normal process that powers up the circuit boards. Right now the TV is most likely in " Protection Mode ". The TV detected a bad circuit board and it will prevent the TV from fully turning ON. This keeps the other circuit board from being damaged. The power light blinking is a code.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet. This will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, blinking light codes, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Dell xps touch sreen just blinking blue light but blank screen


Sounds like it went to sleep due to low battery power. May be time for a new battery if it isn't holding charge well.

Plug it into the wall and push the power button once. It may come back on. If not...

Hold the power button down until the machine shuts off completely. If that doesn't work, remove the battery.

My Panasonic TC-P50VT25 just went dead (blank screen). The power light blinks 13 times. I also noticed that the fans are not running.


The power supply is the first place I would start on this one. You will have to meter the outputs to the other boards to verify this.

There is no reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.

Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).

Sony KDF-46E2000 - Screen Goes Blank


The lamp can cause the picture to cycle without spitting out a lamp error. I'd replace the lamp and clean out the dust/dirt from fans, etc to hopefully resolve your issues.

Sony KDF-46E2000 - Screen Goes Blank


You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!
