Re: Dell H235P-00 recap
This thread is still useful in august 2019.
You made me want to repair my H235P-00 which only provided 1V on green PS-ON.
I had 320Vcc on the 420V/150uF. I did'nt change it.
I only replaced the bulged capacitors (3x 2200uF, 2x 1500 and 1x 680uF) and everything works again.
Thanks from France

Re: resistor wattage help
Thanks Nickon51 but the bn4400155a does not use the same ICs. No F9222l nor Viper12A on the bn44-00155a. The 00157a seems closer but has no Viper12a. No schematics for the 158a
I changed the bridge rectifier and the burnt RM801 .22R. The fuse does not blow up any more.
But no luck, I have 650V after the mosfet on the PFC-DC point arriving on the F9222l thru the RM801.
Is it due to a bad mosfet (11N60C3) ? Or something else ? ...

Re: resistor wattage help
hi,
my bn44-00158a is burning its fuse. The TV is a LE23R86WD.
RM801 (0.22R) is burnt too and CM801 (18pF) is cut (tested unsoldered).
What can I test to find the cause of the short circuit ?
Thanks...
