Subject: [TechAssist] Philips 20" Chassis#20B800 R425 burns up
> Philips 20" M#PL7120-C121 C#20B800-7562. Unit came in dead with shorted
HOT. After replacing HOT unit was still dead. Found open R425, and replaced.
Unit turns on now but R425 smokes.
> Would someone please verify value/specs on R425. I think it is 22ohms. If
my value is correct, any ideas on why this resistor is cooking. I do not
have a schematic on this model.
