TDK VYK3637 SMPS Power Supply

[Carm99]

Hi
I've got a couple of these that need some attention.
One powers up the machine but cuts out after a while.
The other one doesn't power up at all.
I'm sure it's only a couple of components causing it ,hopefully.
I've recapped both of them. One worked after ,the other one didn't. I want to keep the repairs cheap as I'm trying to sell the machines they go into.
Would anyone be able to give me a rough estimate on the cost.
Im in the london area.
Anyone have any recommendations for repairs in the the area.
Ive contacted a couple already just waiting for a reply.
Any experts on the machines they go into would be welcome too.
They are Panasonic M11 AU62 and AU65.
Thanks

Please post a picture of both sides of the circuit board in question we might be able to help you figure out what could be going on with it

Re: TDK VYK3637 SMPS Power Supply

there is a tiny cap with black marker on top you didnt change - it's most vulnerable from heat

Re: TDK VYK3637 SMPS Power Supply

Thanks I'll change that.
What I really need is a tech to look them over and test them.
See what's going on with them.
Cheers.

Hi it's more Willesden.
I can't do much at the moment. I just wanted to find out if anyone could test them ,check them out. I doubt it's something major. Hoping it weren't too much to fix and that kind of thing.
Cheers.

Hi again.
I sold one of the MII machines. Buyer wanted to repair it himself.
I’m left with the one that doesn’t power up at all.

I pulled 2 rectifiers (B92M) out so far to test them ,and got an extra reading on one of them. Any ideas.?
Thanks

I removed another B92M and got the extra reading on that one too.
