Nash LCD TV NTFT-3203CX screen on then off

chandra:
I checked the inverter board.It uses OZ9966SN chip.24 pin smd package

ProDave:
The "trick" is to connect an LED from pin 10 on the OZ960 to ground, which is pin 6 on the OZ960. This disables one of the protection modes.

You will need to look up the datasheet for the OZ9966 and compare it with the OZ960 first to see if it's broadly the same device and if so which is the equivalent of the OZ960's pin 10.  IIRC the OZ960 is a 20 pin device.

chandra:
I searched internet,anywhere I did not find the schematic or datasheet for the chip OZ9966SN.Anybody have it.Please.
