I have a 50PF7521D/10 with a Y MAIN board faulty

The problem is it has the 4 zeners faulty (short circuit),can someone knows what are the part number or the zener voltage ???

on the zener diodes it was marked P758ST but I cant 't find anything on google

attached you can find the part number of board and where the zener is located

Thanks

I believe these are the ones 755-UDZSTE-1733B (33 volt). Looks like 36 volt zeners would also work

Common failure. Unknown as to why this happens but usually that repairs the ymain back to normal operation

Re: Philips plasma tv

Are you sure it's a 36volts zener,because on the FUSE (F5004) that was blow up their was at around 700v dc.
