Philips 55pus6162/12 repair?
« on: July 13, 2024, 11:43:04 am »

 Hello
 Have the TV (philips 55pus6162/12) switched on, after about 1 hour a bang was heard and the display went black, only the on/off led light was on, disconnected all cables and tried to start again but the same result, black display and led light  on.
 What could be wrong?

Found broken condenser.

 Found broken ceramic capacitor C8113 100pf on
 Powerboard, can you continue troubleshooting without voltage with diode measurement?

 Power board
 TPV 715G8672-P01-000-002H

How do I measure these 2 black ones, are they transistors?  Closest to the cracked capacitor (blue)

^The only thing that should be measurable is the body diode between D-S. Otherwise it should measure open.

Beign in-circuit is will measure some resistance, but fets usually fail short and explode.
Check if R8101 is alive, should measure short (0.1R).

Measure resistance in each transistor, between legs 1-3, 1-2 and 2-3.

Mosfet 1 
1-3= 00.00 ohm
1-2= 00.00
2-3= 00.00
Mosfet 2
1-3= 00.00
1-2= 70.5 kohm
2-3= OL
