Re: RCA 32V434T chassis ATC010A



I think that too.
There are 2 grounds!!!! One for primary circuit, and the other for secondary circuits
When you measure 5vdc for example, you must connect your voltmeter to the secondary ground point!

Be carreful DO NOT TOUCH primary ground(live ground) and secondary circuits ground with your hand in the same time!...

Re: RCA 32V434T chassis ATC010A

Hello,
As i see in your description 5V stan-by is 42!! i think you d'ont have feedback from secondary part of psu
I suggest to recap 100% PSU(small one-5vdc st-by and bigger one), after that check and replace if necessary: ic 804,d 869, q 860, and resistors, capacitors around ic 804.
After that i suggest to check regulators (5v ,3.3v,1.8v..etc),and maybe your main ic from tv is broken.
Check bigger power supply and do the same like a say(check optocupler, ic 803, etc).

Re: iMac G5 Power Supply Voltages

Like Toasty say, recap it 100% ,even if caps looks good(no leaking,or bulging), in time will be,"cooked" by heat and loose capacity. I've seen this in many situation.
