it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.

SOURCE: my sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

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

SOURCE: TV Powers off after 30-45 mins

I had the same problem with my 1 year old 26" TV. I called Magnavox customer service, and they had me upload a new software driver to the TV - which didn't solve the problem. Then they suggested that I call the local Authorized Service Center - and they estimated that it would cost $200+ to fix the problem. But then I found the "remove the back solution" listed here - and it worked!
Thanks, you saved me at least $200.

My son got tablet for Christmas t took initial charge. worked fine this morning now it wont turn on or charge. any suggestions?


Is the green charging light displaying on the side of the tablet and/or does the screen indicate that it's taking a charge?

When you hold down the power button for 30 seconds or more, does the screen indicate anything? Charging? Battery low? Charged?

If it's new (and your son doesn't have any/much personal files on the device it's probably less headache to just return it to the store and get a replacement.

VIORE DLP goes off 30 seconds after i switch it on


Listen closely at the rear of the set for any noise from a fan. Most projection sets have them to cool high temperature areas common in these and if the fan fails, the set will shut itself off before any heat damage results. If you hear nothing, use a portable fan directed at visible openings in the lower cabinet and see if this delays the shut-off of the set. If so, the fan is likely dead.

Sony KDF-E50A10 50 in. HDTV stays on for 25 - 30 minutes then shuts off by itself power stand by light flashes green and turns back on in about 20 seconds by itself. can you help?


Hi, Lamp of TV getting weaker and requires replacement. This shut off by itself will increase day by day until you put new lamp in TV. Always Buy Sony original lamp and avoid aftermarket/ cheap lamp for TV safety.

Keeps turning off by itself after about 30 minutes


Is your air intake clean or clogged.. Maybe it's overheating causing it to shut off.. Had the same problem didn't replace the bulb but cleaned the intake and it works great again. Worth a try.. Intake is located on the left back pannel of the tv.. outside pannel pops off easly.

A convergence problem is very commond. In most cases the convergence output amplifer IC's need to be replaced. This is not something you should do. Call a repair shop.
