Probable defect in the main board. I found a seller selling a Philips Main Board 32phg5109 / 78 - 715g6210-m0d-000-004n in perfect condition but the board that is on the TV for repair is 40PFG6309 / 78 - 715G6210-mod-000-004N.
My question is whether you can put this card (32phg5109 / 78 - 715g6210-m0d-000-004n) in place.


I found another Philips TV Main Board 40pfg6309 / 78 Board with Defect (League appears right on Philips and stays on the Blue screen. Lights up the led when activating the control, but does not turn off.). This defect reported among (...) is it possible to perform repair?

Describe the defect in full and measure the main voltages and signals.

the led on the front panel of the tv is off. The main board is defective. Testing some components of the main board I found the U706 integrated very hot. Either the U706 is damaged or another component nearby is causing this heating in the U706
the main board code is: 715G6210-M0D-000-004N
the ideal would be to see if the main board has any chance of being repaired.

turn off U706 and measure the resistance of the power line.
