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​...

Good afternoon! I have this TV with a Chinese combo plate. The symptom is that you turn it on and the standby LED goes on for a while, alternating red and green. In the end it remains green, but without image and without backlighting. I have measured voltages and they are fine, even the TCON has its correct reference voltages. I think it must be a firmware problem. What do you think?

picked up a tv and when the power is plugged, the standby light flashes real quick then goes off. of 3.3, 12, 24v is all there but i couldnt find any 5v on the back-end board. ON/OFF is low, which it seems is what turns on the backlight so i removed the wire at the back-end board and put a 10k resistor to the 3.3v, which when plugged in brings on the backlight for a split second and also a blue light "LED1" on the inverter board, which goes off after a short time.
am i missing something to bring on the backlight or is the inverter/ccfl gone bad? would that cause the inverter board...

Hi, my TV image started showing those lines and the image faded away, but sound is still coming from it, what could be the cause and is it fixable? I thought it could be the tcon board but I red on the internet that it could be a failing panel
