Hello
I have an Insignia NSL-42Q-10A LCD TV which doesn't turn on.It has the only the standby light on!
Out of all the output voltages, i only get the 5v standby which is normal i think,but when i press on the power button, nothing changes.i have the following output voltages
On/off --remains low.( by the way what's the purpose of this signal?)
24V remains low.
12V remains low.
5V always high.
PS_ON always low.
So clearly, the main board is not sending the Ps-On signal to turn all the voltages ON.I confirmed this by jumping the PS-on signal to the stand by pin, and all the output voltages went high expect the ON/Off signal.
I think that the mainboard is faulty, but just wanted to confirm that i'm on the right track and i'm open to your suggestions guys.
I have attached the service manual of the tv( the manual shows Haier brand, but it compatible 100% with my Tv.
thank you guys
