I have a Sony kv-27fs12 the picture go out but you still can hear it and the standby light turns on first it flash 5 times then stop and do it again now flash continuously please if you know let me kn

Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective. If you want to know more about the blinking codes to Sony Brand TVs, check this link.

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.

No Power Sony KV-27FS12

IF the unit is completely dead (no standby light at all) then teh main fuse is most likely open. Try replacing that first. If the stnadby light is on, then when you attempt to turn it on, the light shouild blink. If so, the blinking should be a repeated count with a short pause between sequences. Post that count here as it will indicate what circuit has the problem. We will continue from there.
