Re: samsung bn44-00115a power-inverter
Thanks a lot! After I connect correct zener, TV is turns on about 30 minutes, after that it turns off for few minutes and repeat this sequence each half an hour.
I changed IC101 because it was exploded and PC101 because it was always warm.
I tried to change D102 and D103 without success.
Could anybody help me, please?
Thanks in advanceLeave a comment:

Hi guys, I've a problem with this TV. I repair switching exploded but it switch off after 10-15 minutes, probably because some components get hot for wrong value.
I'm looking for correct value of ZD 101, ZD 104, ZD 105. I've got schematic diagram but I can't undestand correct value of these zener.
Thanks in advance!
