G'day Lee, sounds like you may have a 'dry joint' meaning the solder has come adrift, to open the back up will need special tools to fix it. Hope you can get it fixed. Cheers Greg.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

Tv light standby red just keeps blinking after replacing bulb


Hi,
If red light was not blinking before lamp replacement and after that it start blinking 3 times then pause for three seconds and again blink, check lamp cover that has not been fixed on tv or it is not fixed/ seated correctly there.
Lamp cover is first thing that you removed from tv to replace lamp.
Hope these info will help. If red light is blinking other than 3 times, let me know how many times it is blinking along with tv model number written at rear to provide you helpful info.
Thanks.

Hi,
If red light blinks 3 times when tv refuse to power up then check lamp cover that was removed to replace lamp, make sure lamp cover is fixed in its position securely and screw is tight.
Let me know how many times red light is blinking after three second long pause IF it is not blinking 3 times.

My Sony Bravia will play for less than a minute and then reverts to standy. Any suggestions?


Please unplug tv from wall socket for minute or so,, replug back in and turn it On.
If tv still goes to standby itself than its standby light would blink to show an error in somewhere inside tv circuits.
Let me know how many times standby red light blinking? There would be 3 seconds long pause in blinking so count pause to pause to determine problem section.
Thanks.

Flashing red light on front of Sony Wega flat screen tv


Normally, this happens when the TV detects a bad circuit board and goes into " Protection Mode ". The blinking red light should be a error trouble code. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


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

Check your CRT boards on the end of the tubes for burn spots, and burnt components, check the resistors to make sure they are not shorted, burnt, and they read the correct resistance. Check the diodes to make sure they conduct in one direction only and are not shorted or open.

Sony - Projector TV won't turn


Sony TV;s will give a service code, count the blinks, eg; 2-6, light will blink X amount of times, hesitate & blink again so many times. Count and report back but, I would recomend to unplug the TV's power cord, to reset the TV's system. Unplug for at least 3 minutes. I hope this was helpful.
