Repair Kit, Acer AL1716A, LCD Monitor - Supply please?

The capacitors BigTech referred to are C110 & C111, 820uf-25V Electrolytic, on the power supply board.

With minor soldering skills, you can replace them with Radio Shack in-store capacitors, Stock # 272-1032, 1000uf-50V Radial Lead Electrolytics for $1.59 each. Works great!

Four bucks and little bit of time saves the monitor.

savato321, Most black screen lcd monitor owners don't have the smarts to open up their monitors to do a VISUAL inspection of the "switch-mode-power-supply/inverter supply!!!! You're good. Now you will need to know some stuff about electrolytic filter capacitors! First, the "uf" or "UF" means micro-farad! It is just a rating given to express the storage capacity of the device. Next is the voltage rating. A 16v rating means that the capacitor should never be placed in a circuit where the voltage will exceed 10 to 12 volts DC. Your 820 uf cap rated at 25volts will most likely be in a 12 to 18volt dc circuit. Now for temperature rating. All caps have a maximum temp rating. Most clock radios, stereos, will use 85 degree centegrade rated caps. Printers,PCs,monitors, will use 105 degree C rated capacitors. Never replace with lower specification units! You can GO up but never DOWN. If 1000uf 25v is all you can get it's OK. If you can get 820uf 35v units and they are not too big and they will fit on the board sure you can use them. I would stick with the OEM design voltage rating. Electrolytic CAPS are polarized!! You must replace them + to + and - to -!!! If you screw -up they will blow-up!! The wire lead closest to the printed STRIPE on the cap will be the negative and the unmarked terminal will be the positive. If you visit www.ccl-la.com/badcaps.htm you will get more info on recapping your SMPS. You can also watch some DIY videos at YOUTUBE for "lcd monitor repair" that might be helpful. Also visually inspect the SMPS/inverter printed circuit board for "COLD" FROSTY looking solder joints. They should all have near mirror finish to them. Let us know the name of the BAD CAPS you remove from your unit. You may even want to document with pics with a digital camera what you find. Well, good luck guy. 12fixlouie

You are right about the problem on the flourescent, but the issue is caused by the mosfet transistors. You need to use a flat screwdriver to pry the back of the display until you get this open. Start from the bottom side because some damage will be left on the plastic.
