Question about Proview PL913S 19" Flat Panel LCD Monitor
Proview model pa 19dk5 900t chassic it first started coming on then going to blank screen now wont turn on at all
Ok I have posted a fix for this but I will do it again it will require some soldering technique unplug the unit from the wall and the computer and set it down on its face(lcd side down) open the back of the unit and disconnect the lcd unit and the backlight power leads. remove the screws from the power unit cover. remove the screws from the vga board then gently pull up the board turn it over and you will see a grouping of 6 capacitors that are blown you may also see another single 120 mfd at 25 volts blown the capacitors are rated 470 mfd at 25 volts but look at the side of one when you have unsoldered it to make sure you get the proper capacitance . make sure you solder in the capacitor the correct way there is a neg and pos side to them and they switch sides halfway through the reworking. reassemble the unit and plug in the back light power leads and then plug in the lcd unit to the vga lead make sure its securely pushed onto the connector re screw the ten screws and then reattach to the computer and plug in the wall and the lcd should come back to life. be very careful doing this kid of work
