I have picked up this TV and I couldn't find anything about this issue.
It turns on for like two seconds with nothing on the screen(no BL), just the red LED and then begins blinking the error 2.
This error points to the main power supply.
I have measured all the pins at the PS and to me the only fishy voltage is the BL_ERR and the T-Con is not getting the needed voltage.
here are the voltages:
CN6150 connector:
T-CON_ON= -0.004v
T-CON_VCC= 0.092V
DIMMER= 2.96V
BL_ON= 0.046V
BL_ERR= 3.32V(TV ON OR OFF)
REG 12V= 12.71V
AUDIO 12V= 12.72V
POWER ON= 3.3V
AC_OFF_DET= 2.75V
STBY= 3.32V
Main caps= 396V
CN6702 connector:
12V= 12.67V
FB= -.0001V
GND= 0V
LO= 12.02V
Capacitors are KMG, KMZ. I don't see any bulging.
These voltages are there only for those two seconds and then they are gone, except the STBY and the BL_ERR.
T-con fuse is OK.
Inverter transformers show 139-142 Ohm.
Checked for shorted FETs or diodes, couldn't find any.
No visible damage.
Here are some general view pictures. If specific areas needed, just ask.
I would appreciate any input.
If I fix it, I may keep this one and sell my 46" Samsung.
