Good day.
Have you tried first resoldering the terminals in the circuitry?
Also, try to check for the ABL supply near the flyback. Watch out for the small voltage zener diodes.


response is highly appreciated.

When i try to turn on my sony kv-27fs12 keep turn off and blink 4 time a red led make a pause and keep blinking 4 times, what that could be?


Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
Vertical sweep failure. Check all the solder terminals to vertical output IC. If it do not help, replace that IC.

Sony KV-20Fs100. Same problen as #4620488. TV


Hi,
4 blink of power led shows problem in vertical deflection section and most probably vertical output IC is defective, replace it to fix the issue.
Regarding .rar file type of service manual files, download winrar software trail version from internet, install it and use it to unzip .rar file to get pdf manual file.
You wont get +B volts because tv switch to protection mode and power supply shuts down. Service manual has blinking standby led error code details as well.
Thanks.

Kv-32fs16, no picture or sound , red lights flash 4 times


Hi
In sony tv`s the 4 blink code(sony error codes)usually means that there is a vertical deflection problem.
It is often caused by a faulty vertical output i.c and/or related components. If you feel handy with a soldering iron let me know and i`ll help you with it.
Hope this help Merry Christmas

Standby lighy blinks tv won't turn on


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.
