Like quite a few other people on this site, I have the TV turning itself off, with the flashing red light business.
We always turn the TV off completely, never leaving it on standby. When it's been left turned off for a long time, eg overnight, the next day it behaves itself, operating with no problem. But, if it's turned off and then turned on again a short time later, say half an hour to an hour, it starts this turning itself off business.
Does this put a new spin on things?
Also, as one of your members has said, if the number of times the red light flashes is a code meaning something, can he give us a list of the different codes' meanings, please?
Thanks,
John.
Yes my problem is precisely the same, i have removed the cover and brushed it down, even used a vacuum cleaner, but when i switch it on, 5 minutes later it goes off, i did not notice that anything was over heating. when i let cut the power to the TV for approximately 1/2 hour and power up again, i may get max. 15 minutes of viewing.Yes my problem is precisely the same, i have removed the cover and brushed it down, even used a vacuum cleaner, but when i switch it on, 5 minutes later it goes off, i did not notice that anything was over heating. when i let cut the power to the TV for approximately 1/2 hour and power up again, i may get max. 15 minutes of viewing.

likewise, problem with the flashing lights and not coming out of stand by. flashes 2x then 7x then repeats 3x and won't turn back on...really fustrating. Is it easier to just replace the set, or is there a quick repair for someone that knows nothing about the inner workings.! cheers

Re:
John,
I do not know of a code, but it is a good idea in the design to have several goes at starting a circuit, before completely shutting it down.
Oscillators are supposed to self start due to noise generated.
Some electronic circuits require a reset pulse to be generated before the start up is allowed. The reset circuit may not be generated if the set is turned on again too soon, so it will stay in standby.
This may normally be a few minutes to 30 minutes so it seems something in your set is faulty and could get worse.
Try a test run with the back off and clean it out of dust with a long brush to keep it cooler. Make sure little fingers cannot get near it.
Look to see if anything is obviously overheating.

1. Why hisense TV red flashing power light has sound but no picture
There could be a few reasons why your Hisense TV has a red flashing power light but no picture. It could be an issue with the TV itself, the power supply, or the input signal. Let's take a look at each of these possibilities in turn.

One of two things can be the problem...one the bulb is bad...two the ballast is bad. If the bulb is not bad then the ballast is...it can usually be fixed by replacing a resistor on the board itself...it is labeled R3 and is a 1000 ohm resistor
2 things will cause this Lamp is defective, or Fan to lamp quits running this will shut TV OFF, if the fan quits running while Lamp is on it is design to shut Lamp Off to prevent Damage to Lamp IF Fans are ok It will be the Ballast board It is what turns Lamp on.Look on E-Bay for Ballast board if it turns out thats what you need or call Encompasss Electronics 1-800-638-3328
or a new lamp. you could first replace the lamp. the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.
So far you have done all you can and you have done everything right. The fact that the TV turned off by itself and then turned back on by itself suggests that one or more solder joints have come loose inside the set. A qualified tech should find this easy to fix, and Sony sets are always worth repairing, so it is now time to have the set serviced by a tech experienced in Sony standard sets.
