Its main digital board should be suspected. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact any experienced service technician, or the nearest service center.

As far as fixing goes, you might as well get a new TV... Unless its a LARGE EXPENSIVE HOLY $%^# TV, It will cost more to fix, than to just buy a new one, unless its under warranty, which being an older model as that (or so im reading) It may not be covered.

Try unplugging the TV, and while unplugged, hold down the power button for a full minute (yes, with the plug NOT in the wall) after a minute, plug it back in, and try. Its a hard reset. If it still does not work, and you've tried different outlets, It's probably a repair issue, and you'll need to get someone to fix it, or just junk it :-/

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..


If you are having some problems with your Sony Television, then this post is for you. Generally speaking, when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself. In some cases, you may be able to repair the television set yourself -- or in the worst case you may need to order parts, call a local repair shop to the have a repairman sent out, or even purchase a new television set.

First off, here are the list of codes and what they generally mean on my set (which applies to many recent model Sony Television sets. Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue. Here are the values of the various blinks.

* 0 times, Diagnosis: Power does not turn on. Possible causes include: Power cord is not plugged in, Fuse is burned out (F6001) (G board). Symptoms of the problem: Power does not come on, No power is supplied to the unit, AC power supply is faulty.
* 2 times, Diagnosis: B overcurrent (OCP). Possible causes: H. OUT (Q8024) is shorted. (D board), +B PWM (Q8035, 8038) is shorted. (D board) Symptoms of the problem: Power does not come on, Load on power line is shorted.
* 3 times, Diagnosis: +B overvoltage (OVP). Possible causes: IC501 is faulty (G board), IC5002 is faulty (G board). Symptoms of the problem: TV has entered standby mode.
* 4 times, Diagnosis: Vertical deflection stopped. Possible causes: +- 15V is not supplied. (D board), IC8003 is faulty. (A board) Symptoms of the problem: TV has entered standby state after horizontal raster, Vertical deflection pulse is stopped, Power line is shorted or power supply is stopped.
* 5 times, Diagnosis: White balance failure (Not balanced) Possible causes: Video out (IC7101, 7201, 7301) is faulty (CR, CG, CB board), CRT drive (IC309) is faulty (A board), G2 is improperly adjusted. Symptoms of the problem: No raster is generated, CRT cathode current detection reference pulse output is small.
* 6 times, Diagnosis: LOW B OCP/OVP (Overcurrent/over voltage). Possible causes: +5 line is overloaded. (A, B boards), +5 line is shorted. (A, B boards). Symptoms of the problem: No picture.
* 7 times, Diagnosis: Horizontal deflection stopped. Possible cause: Q8035, 8038 is shorted. (D board)
* 8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)
* 9 times, Diagnosis: Audio error. Possible causes: +- 19V line is shorted. (A, B boards), IC708 is faulty. (A board), PS701 or PS702 is opened. (A board). Symptoms of the problem: No sound

If you would like to attempt a DIY, you will need a service manual to guide you. You can find one here:

However, be aware that there are voltages inside your TV set that can kill, even if unplugged.

Multiple issue,power light flashes


Sounds like first loose connection on circuit board. I would first look around the relay this is what clicks. Then also the low voltage transformers. These problems are always concerns when set is moved or bumped hard. Try this first. Or it could be a heated issue.

NO Picture or Sound


sounds like someone rolled over on the remote. if you have cable or a dish, the tv channel must be left on a specific station at all times. no matter what channel is on the cable, the television itself must be on the correct channel number in order to receive he signal from the cable company. try hitting the last channel recall button on the tv, not the cable. otherwise try channel 3 or 4 or sometimes 60 on the tv. good luck

Picture is a little fuzzy and does not fit the screen


Good Day, mopar69;

Try this and if does not work, call SONY TV with Model and Serial NUMBERS, this sounds like you may have a defective light engine, and they are having problems with them, and they , Sony, are covering that device.

Restoring unit to Factory Preset Condition

1) Power off the set (set is now in Standby Mode).
2) On the remote, Press DISPLAY, CHANNEL 5, VOL +, POWER.
3) On the Remote press CHANNEL 8, ENTER.
4) Wait until Initial Setup is displayed.
5) Turn off TV sets power by the Remote or Front Panel button.
6) WAIT AT LEAST 3 MINUTES UNTIL THE LAMP COOLS DOWNS BEFORE UNPLUGGING OR DISCONNECTING THE AC FROM THE TV. If the set is not allowed to cool down the lamp may be damaged by excess heat build up.

I hope this was helpful, Good Luck, big IRISH.

Channel keeps changing


It sounds like a stuck button or switch. What happens when you hit the channel DOWN, does it still keep scrolling down?
Is this with or without the remote?
Have you tried it with the remote and or the TV?

Let me know whether you are changing the channels with the remote or the buttons on the tv and I can try to give you a couple more suggestions.
