Question about Televison & Video

2 Answers

Hi, Our tv has stopped working. it sometimes goes off and you have to disconnect it to get the picture back, when it comes on it flashes the on/off button from red to green for a while but today it will not turn back on and the lights flash constantly. When you turn it on it tries to start and then there is a click sound on the left hand side (as you look at it) then the lights flash red/green. It looks to me like its not making the circuit so maybe a fuse or the like, hopefully, any help greatly appreciated

    Hi, we live in the channel islands between england and france, the cost of our goods is way more than the average cost in england, the tv cost my daughter £1250 and she doesn't have that sort of cash to throw away so is there a way of getting a circuit board or whatever is required to fix this thing from a supplier or sony?

The TV is on protect mode. The clicking sound is the protection switchthat keep turning the TV off to prevent further damage, this happenswhen a fault had been detected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Alsoensure that the fault is not coming from a faulty receiver box sendingbad signal, check if you get same problem with no receiver boxor dvd connected.

If that does not work, and you keep having a flashingled on front of the TV, and tv turning off by itself after a while,that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1Theinternal circuits are jammed because of electrostaticcharges accumulating on capacitors, or because of a wrong voltage readby the main chip on your monitor controller board. this started theprotection circuit.

2 The protection circuit detected a wrongvoltage or abroken contact, identified an internal fault and kicked in, startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faultsthat can occur are a blown capacitor on power board, aconvergence IC has blown, or a fault on Digital board.

Check alsothe video cable or any external connection cable, if the cable is shorting, or the connector is bad, youcan get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

This is caused a shorted high voltage section in the main circuit board, the cost t repair this problem is around $600.00, u are better off to replace the set with a new LCD, they can be had for less than $1000 (42") from Costco and Sams club.

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,
Lee

Have you checked all of your cables to ensure all are connected properly and are tight? If you disconnect your 'system' (which I'm guessing is an audio system?), does the TV work correctly?

Picture starts flashing slowly and then more rapidly


if your handy and know your way around , open the TV to get inside and do a visual check for any DRY SOLDER on the PC board .specially around the POWER SUPPLY AREA and the
horizontal output area , those area gets a little heat on the board . do some REsoldering. if you can take out the PC Board
and do the inspection , will be much better . hope this been helpful. good luck

I had the same problem and my local repair guy soldered a defective sensor so that it goes around that problem. I also had to buy a new bulb. Now my picture is "cloudy" and the repairman has no idea why. I am waiting for them to call back on it.

Could be a weak Picture tube . You can try turning up the screen control but don't turn it up too much you'll get retrace lines in the picture . Turn it alittle at time until picture comes on then turn it down until the retrace lines go away . Then try turning the tv on and off to make sure it comes back on. Be careful you can get shocked if you do this while it is on and you touch one of the circuits . The control is on the flyback or the module thats on the picture tube it will say screen by it . If this does not work you could have vidoe problems or just the picture is no good . Good luck
