Re: sharp lc52d62u LCD TV no 12V coming out of PSU all other voltages ok
all i see for codes on main board is 2 solid red led and a constantly flashing red led.
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

ok took whole new PSU out of tv and put it on the bench shorted PS_ON to ground.
PSU became active here are my voltage (note 12V still not there)

Re: sharp lc52d62u LCD TV no 12V coming out of PSU all other voltages ok
Also i thought 12V was the trigger to kick on the inverter boards not TCON but i could be wrong
IC5702 is KIA 378R12PI
other pinout on psu board connect small one is as follows
PD cn5703
PS_ON pin 1 2.91v
AC_DET pin2 3,3v
GND pin3 0V
PNL_POW pin4 0V
BU5V pin5 4.98v
GND pin6 0v
also on main board 4pin connector that goes to inverter to trigger on has no voltage, but i suspect this is due to Main...

Sharp lc-52d62u won't power on 5v sub is present
I had a sharp with a bad psu, i replaced the whole PSU we a new one from shopjimmy
part# 184wjqz
i now have all my voltages now correct except pin3 and pin4 that give me 0.24V and should be 12V
I hear tv clicking and trying to turn on now, but no pic or sound.
any idea why i am not getting the 12V out of the new PSU now on Pin3 and 4
