Hi everyone,
Currently I'm trying to repair a CTOUCH CLA-65FHDA1 interactive touchscreen, it's like an interactive schoolboard actually.
I'm not finding much information about this screen.
This is what I tried so far:
Standby light when plugged into AC is on (red)
Screen switches on with remote, stby led turns from red to blue.
Backlights light up very briefly (less than 1 second)
With a flashlight close to the screen I can see that there actually is some image being displayed (video/main logic board seems to be working, I suppose)
Power board is delivering DC power towards inverter board, around 24V if I remember correctly.
So far my troubleshooting suggests the inverter board (DARFON v351-701) or the LED backlights themselves need replacing.
How can I be sure, what is the output voltage of this inverter board?
I can't even seem to find any specs about this board.
Only thing I found so far is this:

As I cannot seem to find a replacement inverter board, there might exist another compatible one ?
Thanks in advance.
