Sziasztok!
Ennek az LCD-nek id. nincs hangja/ most süket/
fejhallgatoról van mindig, a végfok megkap minden tápot ,vezérlés is mérhető folyamatosan.
Végfok IC /2db is/ cserélve.
A kimeneteken a tekercseken csak a nagyfrekis jel látható.
Valami ötlet kellene.
Köszönettel :Laci
Good morning, I am new registered my name is Luigi and I am pleased to be part of this forum.
I have in my hands I have a Samsung TV Mod. UE46F8500SZXZT that does not turn on.
When you give the power command, the internal relay activates for about a second and then returns to the open position, then OFF.
In fact, the power supply (5V) of the standby is there, when you turn it on with the remote control, for a moment the voltages come out, the LEDs on the T-CON light up for a moment.
I reviewed the welds on the most crucial points of the power supply (BN44-00635B), I also tried to heat and cool the most sensitive parts without positive results.
In the end I replaced all the capacitors, the small ones to understand, that are located around the power supply drive circuit without obtaining a result.
I tried to look for the TV scheme and the power supply but nothing is found.
Can anyone enlighten me on this?
Thank you
