Title: A Burned Resistor on Hitachi 32LD7200 PSU
Post by: Kamiiyu on August 14, 2011,10:49:31

Hi Bros,  :oops:

i have a OLD Hitachi 32LD7200 LCD was dead with a totally DARK resistor R72 on PSU board that the resistor ring code cannot read and multimeter also no use because it was dead(open) inside. I'm looking for the value of resistor on that psu board for the hitachi 32LD7200 so that I can buy and replace the dark and unknow resistor.

The part number for the power board is PK101V01610 OR P83033A(SHT832G) :41:

Thank you very much. Looking forward if any one can help ^3^

A bad news Mulja, replaced R72 with 100k ohm 1W resistor cannot switch it on. the LED on front panel does light on red but no green.  Sub-power PCB is ok, Fuse is also ok. Any idea should I need to check? Btw, I just make sure the value of resistor is correct, can you read the code ? I felt the code is straight for 100K.
