Hi Shaun -- Check diodes near the caps you changed, if any are bad it will cause caps to bulge.

Here are a few more things I found in my notes from past repair jobs of that set ...

Check the connections on IC 1019 located on the B-board #875966950,

Replace the B-board #A1300914A, the board should be located above the tuner assembly

Hope this helps, Dan

Partstore.com carries major electronic parts, open 24 hours. if you can disengage the tuner section, then power up. if stays on! then tuner is the problem. if it does thesame? better off get rid of it.

I have a similar problem see:
I put in a reccycled B-Board and same problem as before. The power led lights up, the fan comes on, the screen flashes very quickly a white light, the sleep timer light flashes once, relay RY101 clicks on the power switching board, then the power goes off - shuts everything off - remains off for 30 seconds and same happens again. This will continue 2-4 times then it shuts off.

Is this still a B Board problem - did they send me a bad BBoard?

I am to get a second new B-Board today and will let you know what I find out.
Do you have a pictorial layout of the Power switching board Sony APS -192 part no:1-468-720-11? Can you send it to me - I can not find it on the net.
Thanks
