Sony KV-32FS120 blinks 4 times

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.

Hi Ullah,

LED blinks four times on KV series means that the Vertical deflection circuitry encountered a problem. You can repair it yourself if you have knowledge in electronics, knowledgeable in soldering and desoldering of parts on the board.

(V -stop) vertical section is faulty, bad soldering on vertical ic. or faulty vertical ic. also check for 13v-+ supply for vertical deflection...

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.

you have power issue. short the prongs for a minute. then remove the short wire. then test. if not succesful go to your nearest service center.

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

Hi,
According to the symptom on A Board +13volts not being supplied, and this is due to IC561 Details(Part No. and Description) of IC is given below:

8-759-980-58 IC TDA8172

which is not working please replace it and your tv work fine again.
Thanks for using fixya.
