Sony KV_#^FV1 Was using air compressor in garage, and circuit breaker tripped and killed all power in garage and living room. Turned power back on and tv would not power up. All it will do is click on power supply board and flash the red standby led. Using remote or tv power switch. ?????????????????????

I have mentioned the list of no. of flashes and their solution:


ONE Blink--- not used for the self-diagnosis

TWO Blinks---B+ over current protection (OCP) , unit goes to the standby

mode then displays the 2 blink fault. Could be a short in the power supply of

any of the circuits.

THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby

mode then displays the 3 blink fault. This is also a problem in the power

supply circuit, check T603 and R672.

FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single

horizontal line then the video signal muted. Check IC1509, Q1505

FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking,

try turning up screen slightly.

SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis

function immediately. Check C515 & 516 and the jungle IC, IC206.

SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k

and the unit goes immediately into safety shutdown. Check power supply

regulation and horizontal circuits.

EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and

blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.

Intermittent problems ?? This is a great feature. You can also bring up

these fault codes ON-SCREEN to see a list of the problem numbers with the

abbreviation of the problem and the number of times this problem has

occurred. This is slightly different than entering the service mode. To see the

diagnostic screen, Press the following buttons:

Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up

a screen with a list of the problems and number of times they have occurred.

Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.

We have repeated them in parentheses in the text for the "Blinks" described

above so you can correlate between the diagnostic screen and the blink

codes.

So, now that you know about these self-diagnostics, how do you use them?

Say that you have a set with a black screen. You see that the LED is blinking

4 times....This would tell you that you have no vertical and that is why the

video is muted. If it was blinking 6 times, you would know that you have a

horizontal fault.

It's not a sure cure, but it's a little better than a poke in the eye with a sharp

stick.

IMPORTANT: after you repair the unit, PLEASE clear the values on this
diagnostic screen. These codes do not reset themselves after the fault
is 0 corrected, so if you don't clear them, you'll be seeing "old"
fault codes the

next time you enter this screen. Clearing is done by going into the
service mode ( display, channel, 5, volume plus, then power ) then
press 8 and Enter, which of course returns

everything to the factory preset condition.

you cannot solve this problem without the help of a technician.so dont try some thing else call the service centre as soon as possible and get it repaired. you cannot solve this problem without the help of a technician.so dont try some thing else call the service centre as soon as possible and get it repaired.
