Monitor sizzled when turned on

I have an Acer LCD Monitor X221W. When I turned it on this morning, it made a sizzleing noise and will not work at all now. I purchased the monitor on November 20, 2007. Can I get a replacement? I purchased it from the Micro Center in Dallas Texas.

It's seems you've got a busted backlight inverter. Sure you've got a 3yrs warranty for parts.
Send it back for repaired...

L246WH Monotr makes a sizzling noise and flickers

Safety note: For best safety practice, unplug the unit immediately. If you want to try and diagnose and/or repair it yourself, at least move it to an open area free of anything that could flame up in case of sparks or a fire.

Mr. McLellen could be correct about the failing solder joints. Since the symptoms increase as the unit heats up, I suspect it is more likely an electronic component failure. The specific symptom you describe is common in transformers with electrical shorts or with a cracked frame. Insects may also be the cause. Some are specifically attracted to warmth and electromagnetic fields. To rule out insects, take sample whiffs around the vent holes on the back of the unit after it starts crackling and flickering. Electrical burns are distinct from most other types, especially roasting critters.

Acer Monitor Lcd 22 in X221w LCD Monitor Dead.Won't come on when you turn on computer.

You need to check the power secton to see if you do have 5vdc (for logic) and 12~18vdc (for backlight inverter) in the power supply first.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for:
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My Acer x221w a monitor comes on for a couple of seconds and then goes can switch it off and on and it does the same,only lasts seconds. is it fixable

leanish, Yes, your lcd is a viable candidate for REFURBISHMENT! Only I left out the word "MAYBE". YOUR words "on for a couple seconds" is the clue that places you into the "viable" catagory! Your stated symptom is CLASSIC of many thousands of other lcd owners whose screens are now BLACK and lifeless. Now for the FIX it part. First thing to do is visit YOUTUBE! FYI to help you make a decision to do the repair yourself or contract out the work to get your x221w back ONLINE. Search and view the longer vid clips of "lcd monitor disassembly","lcd monitor repair". Learn what internal components on the "switch-mode-power-supply" and "inverter circuit" cause the CLASSIC symptom refered to as the BLACK SCREEN OF DEATH. Also research my other posts in my profile on how to do the "rude&crude" flashlight test that every lcd display owner should know how to perform and interpret when the BSOD strikes without warning. It's not hard to do and you would then have provided another 2 lines of useful information along with AGE and or approximate total "ON" hours of use the unit has seen since the purchase date. One more thing that OWNERS fail to state is if the unit "is" or "is not" under warranty by the manufacturer! Warranty work is the very first thing to check because it's FREE!!! Well, anyway, I wish you good luck in your quest to fix your unit. If you need additional info you can always do a repost to fixya, or I'm 12fixlouie on fixya If this response was of some help then please rate it on fixya. Bye for now.

Most likely the inverter module for the lcd screen has failed. If you can hook up your laptop to an external monitor, you will be able to make sure that the rest of the laptop sill functions.

An inverter is a inexpensive part, $10-15 dollars, but requires that the lid be disassembled somewhat to install it

You could send the laptop in for repair but it could be quite pricey, it sounds like the LCD is toast. If your keypad still works using an external monitor then you won't have to replace that.

Blank screen

Possible that the HV inverter or the CFL tubes are going bad / defective. I suggest to bring the unit to an authorized Acer service center for proper check-up / test & fix the problem. regards
