Re: samsung un40eh5000f
Hey guys is there a way i can manually jump the tv to start up cause i think its not starting up and this model does not hv the red led light on standby when its off thats why the tcon not getting voltage
ThanksComment

Re: samsung un40eh5000f
Which regulator are u referring to on the smp or the mainboard im a bit lost sorry
I have no standby light and i can see the red light inside the digital out going on and off all the timeComment

This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
I have no standby indicator light and no light on the optical port. I checked the standby voltage on the two mosfets in the top left and they both read 30mV. I checked the fuse and it has continuity. I also checked the voltage on the two large 450v caps they both read 153v. All of these voltages are the same with and without the main board connected as well as with backlights connected/disconnected.
Nothing looks obvious like a burned ceramic disc cap or bulged electrolytic. No burned resistors, diodes, or anything like that.... -

Good day, instead of Q0165R I mistakenly put 24C256 (don't ask me how) and made a short circuit. After I put Q0165R I don't have stand by voltage again. There is no voltage on the cold side. I found the schematic.
I checked a few things but didn't find anything. When I checked the DB802 diode, it showed a short circuit, but when I unsoldered one leg, it looked fine, and I still have a short circuit on its contacts. On the other side of the board, I have DZB801 also shorted, but it is SOT23, so I didn't remove it, do you think it could be connected to it? Could there be some protection... -
Hello,
I have a problem with this TV, the standby voltage is not present. I have checked the components around the IC fsq510's area and they seem to work, also replaced this IC but the problem persists.
These are the voltages in some pins of IC fsq510:
Vcc=18v
D=320v
Vstr=154v
Unfortunately, I couldn't find the schematic
What else could I check?
Is it possible to provide standby voltage from an external source to allow the TV to turn on?
Thank you​...
