ORION T2130
Sziasztok! Még új vagyok itt és nem tudtam hova írjak, remélem nem gond. Van egy Orion T2130-as tv-m és az a gondom készenlét van, indításra felvillan a zöld led a nagyfesz pityen egyet aztán semmi, megint készenlét.Sajna már megkoptak az ismereteim, kb 15 éve tanultam a szakmát és már nem igen vagyok benne. A nagyfesz tranyó kollektorán indításnál megjelenik a táp, azaz megpróbál, felmegy kb 30 voltig aztán visszaesik. Ezek után mit tegyek, kérem segítsen valaki. Köszönöm előre is.

Samsung TV UE46F8500 does not turn on led standby on
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
