Blinking/standby timer

There are particular blinks meaning on sony TV. I can give you the problem from your sony tv if you specify or count how times the LED flashed.

Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Hello
Vertical IC inside your Sony TV has damaged [shorted]. Four blinks of standby light denotes it. The number of blinks of standbylight in Sony denotes some fault, and can be determine according the the continueous blinks. In your case, the standby light will blink four times, then stop for a while and will continue to blink four times and so on. Vertical output IC should be replaced with same type and number. If you are aware in electronics and have tools, you yourself can do the work.
If you wants anymore assistance, feel free to get me by Fixya.
Thanks for using Fixya.

you have to check you timinig on/off setting.

error code 4 is vertical deflecton failure . replace the vertical deflection ic. and the electrolytic capacitors in the vertical circuit. Or if you are lucky just resolder the vetical IC and resolder th horizontal section too.

you do have a deffective crt

Hi,

Sony has self-diagnostics built-in to the TV. This is as you noted indicated by the blinking LED light(s). Initially and based on conventional TV sets, the four (4) blinks a vertical failure. This would normally mean the vertical IC requires replacement. In some Sony versions/models, the IC would be LA7835 but this has to be confirmed on the actual part from the PCB. There are instances where the IC is not defective but the diode and/or limiting resistor from the FBT that provides the ~+28VDC supply to the vertical IC that could be defective. As you will note, this is rather a technical repair and not an easy user action. This of course would require a familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Hi again,

I was just checking similar problems and saw that you posted twice.

Pls see your other post here with my proposed solution.

The model number is KV-36FV15 and blinking is constant no pause
