It is due to over voltage form the SMPS power supply to horizontal output section circuit. If this voltage goes higher than normal, the set will shut down, showing two blinks of standby lights. I've recently found one site that details all these matters well. "electro-help' is the site name. Google for it. have all details, and I'm sure that you will get all details.

check all voltage output from secondary ouput of SMPS, specially the B+ going to flyback transformer if open and also h-out transformer oscillator voltage. please call a qualified personnel if your not electronic expert. to avoid of electric shock.

If the lights don't come on the tv ,try to connect the tv to the other power point
and check if it powers on, if its does not power on then its the problem with
fuse inside the tv replace the fuse and check its works ...and also test the power chord for continuity ..

Good luck...

Try going into the audio settings part in your menu and select reset audio settings.

We had this problem, we took it back and they said something about the tubes in it, they had to give us a new one.

This is the most common death mode for TV's. The high voltage is acting up. You set is not quite 10 years old right? Can be fixed, but involves replacing the Flyback transformer which is not cheap. It is a toss-up as to whether it is worth putting the $200 or so it will cost to fix into a set that has limited expected lifetime.

once you have diagnosed the problem, the following link is to all parts for your tv stocked at partstore. they generally have better prices than the dealers and repair shops.

you can try the dead-tv kit from fixyourowntv if you have some basic experience with soldering and circuit repair.

Five blinks means, "IK (AKB)" (white balance). The probable causes listed by Sony are as follows:
1) Video OUT (IC561) is faulty (A board)
2) IC355 is faulty (A board)
3) Screen (G2) is improperly adjusted.

not sure what the 13 blinks are for.

hope this helps,

Go into the video settings section on the tv by pressing menu and reset the video settings.

The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.

call a tech your tv needs to to be repaired the problem is in the power supply and related circuit.good luck.

You may have a bad solder joint on the horizontal driver transformer or somewhere else in the set. I found this problem with this transformer several times. Stargazer

The set may have shorted the horizontal out put transistor since it kept coming on sometimes. This could be cause by the driver transformer arcing causing a "spike" in voltage going to you horizoltal out put transistor. Stargazer

Hello,
I'm not sure if you solved your technical issue or not, but if your TV is still broken, I would be interested in buying the door that covers the AV inputs. This door is on the front of the TV. Unfortunately, mine broke, and it's been difficult to find a replacement. If you are interested, I can be reached at (612) 801-5752 or by email at [email protected]. Thanks.

The set has loose power conections to the tuner and judging by the model it might have other loose conections in the chassis,the loose conections need to be resoldered and might not be easy to find,try taping the side of the set to see if it reacts while is doing the problem.Be safe and call a technician unless you are familiar with tv service.

All questions need 'make model (what is is)' as first 3 words in every question please. Television? Stereo? Sound bar? ICE? The grinding noise makes me think you have a cooling fan issue, in which case the flashing LED would be signaling an overheat situation. You can Google sony model blink codes ..
