UMCE22/13B - suspect PS problem.

[Turnip]

Hi Folks,

Have one in where set is dead and PS (PC40005) has outputs of 5v and 12v but when plugged into main board, supplies drop to near zero. Checked main for shorts on the 5 and 12 but found none.

Notice there seems to be a control chip on PS secondary with some sort of S/by function, but without a shematic - as ever, a bit stuck.

Wonder if anyone has had problems with this PS ?   Thanks - Chris.

Admit - The Main board is a bit like those B'crap - whatsit cheapy ones with the Eeprom troubles, but it's MKT5330C1 - DVD 1.07 so natch again suspect Eeprom trouble as UMC tellies are usually total rubbish.
