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.

The numbers on the IC's are what you need to use to order replacements. Generally, there are no equivalents available without knowing the numbers on the faulty IC's.

Standby light is blinking 9 times. what does that mean and what should i do about it?


You have a bad MCZ. Try taking a blow dryer to the right side of the TV to see if this fixes the problem.

You will have to find these and replace them both on the board to the most left of the T.V. There are two of them. The one closest to the back of the T.V. is probably the problem.

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.

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 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?
