Found cause of low resistance. I've removed U1200.
Now I don't have low resistance but still I don't have PP1V_PRIM. Maybe cause is PCH not installed?
But I think 44ohm is normal value for PCH. There must be moreLast edited by Pragmatiko; 05-20-2024, 06:13 AM.Leave a comment:

I don't know why, but I strongly believe that the problem is on R12,T12,U12..... of U7800 ic.
I've checked all capacitor under microscope. Usually bad capacitor is visible. I would be tempted to desolder the U7800....Leave a comment:

Well,I removed R7820 too and still I have low resistance consumer side. There are a lot of capacitor on that PP1V_PRIM. I will try to test with ESR meter (tomorrow maybe). Thank you for your support....

update, i have removed L7821 and L7822 and now voltage side IC is present. Then i suppose that 44ohm resistance downstream coil is not good.Leave a comment:
