Get rid of the TV imdt. It is possessed.:lol:

Jokes apart, there might be a setting on parental control which your TV might have which any of you esp the kids would have activated inadvertently.

Explore deeply & you are sure to find it.

If you are not cut for it, then you must provide more details like Model number/name & the channels which are affected etc. so that TV gurus in the forum can offer you a solution.

Maybe this helps, fingers crossed. If not service may be required as written.

Btw, your TV is not the only set that is possessed

Many customers have reported this problem with Sony. Seems like a software bug.

hi shaiju_o_thomas-

but- that is a CRT - is there any software in these older TVs?

to me - it looks like a problem with the input voltage - most TVs will not work (and indicator will flash) when input voltage drops below a level.

so - putting a wide-range stabiliser (say 70V to 300V -hehe!! N.A.) may solve the problem.

hope it works for him.

I also believe it should be voltage problems. Evenings being the peak time, Low voltage might be the culprit.

"Of late " What I understand from this is for the past few months i.e during the advancement of summer . There are some TV s work under required power. If you have a Volt Metre , if not try to purchase one, check the input power and see whether there are fluctuations / low voltage during the day particulary at the specified time by you. It is better to clear doubts in this area .

+1 to that as at low voltage area,evening time all houses/shops uses full load of electricity..

I have a VIDEOCON Bazoomba 21-inch 1999 CRT. For the past few years I have been facing a strange problem. During the rainy season, or on a day when the humidity levels are too high, my TV does not start at once. When I switch "ON" the TV after switching the power supply ON from my AC wall socket, the TV does not start. In this condition, I have to leave it on stand by mode for a short time- sometimes for 10 minutes, 15 minutes and sometimes even for half an hour. After this, the TV starts and gives a very blurred picture which after sometimes becomes perfectly clear. Is the humidity factor responsible for this? Explanations and suggestions are welcome from HFV greats.
@harmeetmatta(OP) Please excuse me for putting my query in your query thread.

I think you guys are missing the point. OP says that it happens only when the TV is playing some channels and not all channels.

Or is it that some channels consume more power than others of which fact, I'm blissfully unaware?

Does this happen when you are using your remote,my former old sony crt used to go to the ch no 4 when pressing any button in the remote,due to fault in the remote,so it can also do the same for power.

 

[S.P.KRISHNA]

Sir,
Please move the T.V to another place somewhere to your friends or relative place, where there sould be another the feeder / transformer other than that supplies power to your house and another cable service provider / connection , and observe whether it behaves in a similar way.

Yes there is a lot of software even on older TVs.. so are dedicated microcontrollers... To me this looks like a software problem or at least the TV firmware is reporting a problem on hardware and trying a self recovery procedure. Or it could be some kind of a failed Auto firmware update feature. The red LED blinking normally is an error code indication. At least thats what it is on Philips sets....
