I have a Diamond View 19 inch. The chassis is Acer the main board has a part No. 55.74201.001, the HOT ( BU2032 ) is blown. checked diode D316 (5 TUZ52) is good the capacitor C 365 from the Hot Collector to Ground is good.
Is there anything else I can check before I change the HOT?
Also Can I get a circuit diagram for this unit?

Yes you will need to find the B+ regulator for H-Scan and check that it is not S/C or for an open fusible component in the Scan supply.

Richard thanks for your help.
There is a Fat “IFRS634A” and it is S/C. Do you think there may be something else?
Do you know if I can get a circuit diagram for this Acer?

Is there an FCC on the back or a model number that is diffrerent from the front model number.

Rich

Richard Thanks for your help.
There is no FCC No. anyware.

Richard I found that the Diamond view is an ACER 717IE.
The schematic is exactly the same. But the Hot (Q 314 ) has another number, onboard its BU 2532AL and on the schematic its BU 2527AF. The B+ regulator for H-Scan( Q313 ) is BU 2520DX on both. Everything else is the same. Which transistor is right one or are they the same.
