Hi...
If this unit has a backlit display, it will need a new lamp.
I've fixed Yamaha's and NAD units in the same fashion.

Sounds like it could be a bad capacitor on the power supply, or possibly on the video out circuit. Bad capacitors are a common problem in Plasma and LCD monitors and T.V.'s.

My moniter has a black screen and is blicking blue light. i have a proview model 2200w? Was working fine until i shut down yesterday. I unpluged, nothing happened. Could it be in a sleep mode? If so, how...


this is so common in lcd monitors, its the power suply board.... most likely a capacitor.. so type a model# into google following the words "power suply" it will probably be close to $50-$60... thats better than buying a new one

hope this helps you

My akai lcd 32.5" tv will not stay on and all it does is flash the blue screen with akai then turns right back off and i was thinking power suply might be bad. what could it be?


You could be right it sound like the power suply, has it got a AC adaptor power suply,bit like a laptop charger? goes from mains to a black box then from box to the TV?
does it stay on at all?

Doesnt turn on anymore.


Hi..there,
It's seems your backlight inverter is burnt out... need to be replaced with a new one or you can repaired yourself by testing all the capacitors to see which it has been burnt out or has a leaked. After that just replaced the bad caps... Good lucks, Have nice a day!

Please post the model number. It is not likely the power supply. Depending upon the model, some use a small bulb to "backlight" an LCD. Others use LED displays. Get me the model and I can provide more details on what to look for.
