SOURCE: I have a Sony KV-32S20 32

you first must verify you have horizontal deflection. do the crt fillaments light up? if they dont you probably have a shorted horiz. output transistor short or a bad solder joint in the drive circuit. i would solder this anyway it is a common issue. it can blow up the power supply if it fails. if they do light up turn up the screen control, the bottom control on the flyback transformer, do you have a flat vertical line? if so you lost vertical deflection. that could also be a bad connection on the ic or it failed.

7 blinks


There's a bad MCZ ic. It's got 10-12 legs. There are 2 of them. It's the one located closest to the back of the T.V. You can heat your T.V. up to get it working again using a blow drier until you can get it repaired.

I turn on the tv , sound but no picture and after a few seconds it turns off and flashlight blinks on front panel 10 times and after a pause repeats blinking


Had the exact same problem on a KDP-65WS550.
I replaced IC8002 (MCZ3001DA) and IC8005 (TL1431CZ) on the "D" board and this resolved the problem. Total cost including parts and shipping was around $35.00.

My Sony KP 51W520 won't come on. The standby light flashes 10 times. I read through the other people's problems listed here and everyone else has had either 3 blinks or 9. Any thoughts?


Hi.
it seems that your power supply or high voltage section is failing. Look for PWM IC genarator. MCZ 3001D on Power supply and near high voltage section. Try to replace these IC's.

My tv turn red and blink 13 time


Hi ,
I had same problem my TV. Replaced IC8002 on the 'D' board.
This is what we did:
1.Bought 2 x MCZ3001D from WES components in Ashfield Sydney Australia for $11.20 (each).
2.Friend had an 18 pin machine spun socket (not the crappy ones on EBAY).
3.Took back off TV
4.Put the 'D' board in service position
5.Noted which way IC8002 chip sat (Where position 1 is), also noted which 2 legs are not soldered.
6.Cut the black plastic that was covering this chip underneath (where D board screws into) as this is easier than removing the 'D' board.
7.De-soldered the IC8002 chip with a proper de-soldering iron. These are expensive though.
8.Soldered in the 18 pin socket.
9. Set the chip into the socket.
10.Tested TV, worked fine.
11. Put it all back together, plugged in Tivo, DVD etc etc etc and all bloody good stuff.
12. I now also have a spare MCZ3001D which is taped to the back of the TV for future replacement, which is now easier since its now in a socket.

My Sony Wega KV36XBR800 has no picture or sound, Stand by light blinks 6 times, then paus, then again 6 times. Please help. Thanks Sometimes it blinks 7 times.


ur tv chassis is DA-4 and IC 8002 is no good that is MCZ 3001D.
carefully de-solder and take IC out.
recommend use 18 pin ic socket, so u can push new IC in instead of soldering- fast and easy. do it ur self save $300. happy?

I have a TV sony KP-fx432 sometimes it works normal but the other times it doesnt and the led blinks 10 times there is sound but no picture. please HELP! :[


We had a similar problem with the same model a few weeks ago. With the help of a service manual, we just replaced IC8002(MCZ3001DB) on the D-board to solve the problem. The 10 blinks indicates an HV protection has occurred.I do hope this helps.

High voltage protection. Either transistor Q8014 04 Q 8013 is shorted along with R8051 on the D board or IC 8005 is defective on the D board. Let me know if you need more assistance
