Question about Thomson 24WK25U 24" TV

The flashibg red light

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.

    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

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.

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 cuts off and green light flashes

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.

Good luck!

KV 27S65 Sony Trinitron 27"

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.
