Question about Proscan 19LA25Q 19 in. LCD Television

1 Answer

Green power light comes on for a split second, then red.

I have a Proscan 19LA25Q. When I first turned it on there was sound but no picture. I pushed some buttons on the remote, nothing. I turned it off on the TV then back on and it seemed fine. An hour later my husband turned down the volume and napped. When he woke up it was turned off. He tried to turn it on and the green light came on for a split second and then red. I tried the power button on the TV and even unplugged it for 5 mins. It won't stay green.

    My electrician tested the power supply cord and it showed 5 amps coming out. How can that be if it is worn out, broke, needs replaced?

The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories

    One would ordinarily measure voltage not current (amps). I feel that the electrician measured the voltage, not current. In doing so the electrician's meter does not put a load on the power supply and the power supply would likely read full rated voltage. If you have a cigarette lighter power cord that has the positive terminal in the center hole of the plug, take your tv to your car and power the tv with the car power cord plugged into the cigar lighter receptacle. If the tv powers up (light stays green) that confirms the tv power supply is bad.

When I turn on tv, green light comes on and there is a clicking sound but no picture..is that the power supply as well?


This Proscan 19LA25Q has no relay to make any clicking sound that I can think off. The common problem with this model is the fail backlight inverter board. Did you see the screen flashes on for a second? You should also check the output voltage of the AC adapter, it should be 12vdc with load. Check the surface mounted fuse on the inverter board (this board is really hard to find).

You have a bad power supply (AC adapter). Watch closely at the red light while turning tv on to see if red light momentarily flashes green, then back to red.

Problem with proscan 19LA25Q


Watching a movie tonight...and slowly there was odd behavior from the screen. No volume at first, then flickering, fragmenting and now, as the others only shows the red power. I have noticed some strange flickering the past 2 weeks or so. I thought it may be the cable, so did not concern myself too much. I believed that was the problem tonight as well. But the screen is definately not responding to the remote or manual button.

Thanks
