TV s switched on, blue standby light is steady, turn on by remote or ch +\- button on tv, after about 2 mins tv goes off, standby light blinking. After a seemingly random time, blue light goes steady, turn on again and off it goes, sometimes immediately. PSU looks fine, no bulging/ leaking cap's.. Help?
Hi
The electrolitic capacitors are trickery: sometimes they look like fine but its capacitance has gone. The actual test is to replace them if you have not a capacitance meter to test them. Another approach is to check the Dual Schottky diode for leakage. It looks like insulated transistor and is screwed on a heatsink.

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.

KV32hs500 tv won't turn on. Standby light blinks 7 times, stops and then 7 more times, etc.. The tv will usually come on after about 2 hours or so of being off. Plays fine when on but once it gets turned off the problem happens again. Any suggestions? T.V. is 5 years old.
I have a similar problem . mine blinks 6 times or 7 sometimes also,and comes on with sound ,no picture for about 2 seconds then shuts off. Anything?

Hello,For model KV-40XBR800,
Pls check following area.
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.
And NOTE: 6 blinks also can be Low B+ protection.
Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.
Good Luck

SOURCE: STANDBY LIGH BLINKING 9 times...
I have a Sony SRS BBE Trinitron (WEGA). The last few days when I tried to turn it on using the remote the Red Light would go on but the TV did not turn on. I would have to press the power button again to turn it on.. I tought the remote battery was just low.
Today when I tried to turn it on nothing is happening and the Red Light is blinking 9 times ??? I tried to unplug it and try it again, still does the same thing ???
We need help...
