Can you throw up some good clear pics. of all the individual boards and one of how they are all connected?

Main Bd. issue. Probably a firmware update/reload would be required.

Thank You sirs.

Would you have a link to the firmware update for this RCA RLDED4633A-D TV.

The processors on both the Main Board and the T-Con are very hot.
I installed heatsinks on both processors but still getting a blue screen.


Thank You

The second T-Con Board

So did you verify that you do have 12VDC at both ends of the SMD fuse on the T-CON with ref to GND?
You also have many Voltage test points on that T-CON board that you need to check, I.E. VCC_1.8V, VCC_3.3, and on and on.

Yes sir I did check the T-CON board voltages for 1.8v, 3.3v.
I will confirm that.
Did not check for 12vDC on the T-CON SMD fuse.

I would like to know if the splash screen firmware is programmed into the Eeprom?
Would a firmware update be available for this TV?

Yes there is 12VDC at both ends of the SMD fuse on the T-CON.

There is approx. 1.27 v on the each of input connectors testpoints.
There is 0 v on each of the output connectors testpoints.
I need to verify the Vcc 1.8v, 3.3v voltages.
