Good morning techs. I am working on a Sony kv-36xbr400. When the set came in, it was dead.I replaced the 130v b+ reg which brought my picture and sound back. Now the set works but it will shut off any time (after 2mins or 30mins). I can then power it back on by hitting the power button. When I run the diagnostics,sometimes it will show - low b+. Yes, my130v measures 80v. However, I cant figure out the cause. Can anyone send me the training/troubleshooting manual and tips. Thanks.
