TV Repair Questions? Ask a TV Technician
This TV did not work when I got it. I do not know the history.
Flashes 2 times pause 2 times pause etc.
Yes I am looking to repair it myself. I have not checked anything yet. I do have a multi meter.
The screen does not light up at all.
I have 3.3 volts at AC_OFF_DET and STBY. No power at any other pins. I tested with all boards and backlite disconnected.
Thank you. Can you keep this open until I replace the power board if I have any other issues?
I replaced the power supply board on my NSX-32GT1 Sony. Still have the same issue. When power button is pressed green light stays on for 15 seconds, backlight tries to come on the a second then power light goes red and flashes 2 times repeatedly. With all wries disconnected from power supply I only have standby power.
Mainboard not plugged in. 2 blinks after power button is pressed. When I plug in the tv I hear a relay click.
Looks like I am not getting 12v at pin #6 from connector from power supply to main board.
All other voltages are present. I am grounding the meter to the ground wire on the chassis
Yes I admit I read your message wrong and I do not blame u.
Is the board I need to replace the A-1783-118-A ?
Thank you. I apologize for mistake on my part.
Aric, I installed a used main board. Now both the timer and power lights are on steady and I cannot turn on the TV.
BTW: I do not have the remote.
Nothing happens at all.
When I plug it in I hear a relay click. When I unplug the TV the lights stay on for a few seconds then I hear a relay on the power board clicking fast several times then it stops.
Is the inverter board the one under the main board with the large heat sink?
Well I basically unplugged everything except the power supply to main board and have the same result.
Also checked some voltages on power supply, pin 8 and 9 I believe should have 12 volts but only have .3 and pin 13 which is vcc only has .3 volts. Standby still at 3.3
Question 1 is yes.
#2 back light flashed for a split second then 2 flashes repeatedly with both power supply boards. Then we tried the main board.
I agree it doesn't make sence.
I am going to reinstall all the original boards and start the testing process again. I'm to deep in the TV to stop now.
Aric, I finally got back to this TV. Sony NSX-32GT1. Standby light flashes 2 times continuously.
I plugged in the TV and tested the main connector at the power supply before I attempted to turn it on. I had all the proper voltage. When I tried to turn it on the screen flashed for a split second and I had no power at the main connector then 2 flashes started.
The second main board I tried both the standby and timer lights are green continuously and when I unplug the tv a relay clicks several times then it shuts down.
Do I have 2 bad main boards? What about the processor board?
Yes i did. The second main board I tried both the standby and timer lights are green continuously and when I unplug the tv a relay clicks several times then it shuts down.
I wish I knew how to test the components. I am capable of soldering.
I wouldn't know where to start. LOL
They gave me a refund and told me to keep it.
