The lcd light won't come on - Fuji FinePix 2650 Digital Camera

Not making it on or out of standby---first place to look is the power supply for signs of damage or puffed up filter caps there.

flat panel won,t turn on

Is it repairable, well, this question can be answered only after opening the back cover and evaluating the damage. From you side, please connect the TV to a different power outlet where other similar devices are working and see. Then try changing the input device to something that sure works. If it does not work even then, this may need attention by a qualified service technician.

a problem with the battery or a charger.

Hello
Check the backlight inverter board to your TV. This is a common fault for most of the LCD TVs. If it is faulty, the backlight won't light up, resulting a balck screen with sound.
This is the picture of the backlight inverter board to your TV. OK.

Bad main logic board. Probably won't be able to find it. You can try Encompas Parts. Good Luck to you.

Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Disconect the battery and ECM for FOUR DAYS then reconect the ECM and BATTERY. Let it sit for another four days without turning anything on. It should start but will run rough for about 200 miles as the ECM relearns the system. I had the same issue and that is what fixed it.
