I have a Panasonic 51", Rear Projection TV that goes off while watching it, then comes on after awhile. I've been told this is due to a faulty Standoff Resistor. Can I replace this myself and how much does the part cost?
What the person was thinking was that there is a thermo standoff resistor. This will not be the proper fix if there are other faults. The set is probably going off because of more complicated problems. Something is pulling too much current and should be found and properly fixed.
I would suggest to have the set properly serviced. You may be going to some extra trouble for nothing.
I don't have the service manuals for your set to know the exact component layouts and specs.
The following is a simplified example:
I can tell you that the tech should monitor the power supply while the set is running to see the voltage stability. When the set is in the off condition he should then work on verifying the cause of the shut-down. This involves following up along the voltage distributions through the set, and also checking the drive pulses from the scan circuits to see where the probable failure is occuring. Obviously, if there is a voltage shut-down, the scan drives should also be shut down. Then the fault may be a failure in the supply, or something on one of the boards is pulling it down.
