Question about Proview PT 15.1" LCD Monitor
My TFT 700P display comes and goes when we switch on the computer . Then after repeated on and off finally it comes ON and remains working.
I have checked voltage at 7812 and it is 11.7volt on one side and 14 volt on HT side. when there is no display this voltage is 16v.
Can you suggest some remedy.
Try changing out all of the capacitors on the power/inverter board first.
You probably do not have to change the large main one, Just the other ones.
It sounds like you have voltage but your amperage is not there. the 11.7 should probably be closer to 12.
