Hello, I am trying to fix a GO5-802 that has the spot killer circuit LED on. The screen has a white dot in the middle of the screen if you turn up the brightness.
Here is what I have done:
1. Cap kit. (Bob R.)
2. Checked PCB for X/Y signal, measures good.
3. Checked ZD900 and ZD901, both good.
4. Voltage on pin 1 of P500 is very low.
5. Bridge rectifier checks out ok on HV unit.
6. R100 measures infinite.
Question 1 - If R100 measures infinite (should be 5 ohm 10W sand resistor), could this cause my symptoms?
Question 2 - If no to Question 1, then what next?
Thanks...
