Try checking your Cable connections to the Monitor to the Computer and from the Monitor to the wall outlet.The crackling sound maybe normal.Most Monitors make that sound.

    My W22 monitor did the same thing yesterday. It made a crackling sound and then the screen went black. Everytime you power it down and back on the display comes on for about a 1/2 sec. then goes out. Same with unplugging and re-plugging monitor cable. If I shine a flashlight in the screen i can see the desktop faintly. I have read that it could be the inverter board but how does one tell for sure?

My Neovo E-W22 monitor quit working. I have had it just under 2 years. It is as if it is getting no power. Any ideas?


Make sure the power connector is secure with your monitor and the adapter power light is on as green. If not working at all then just contact with AG Neovo as service.us@agneovo.com for 3 yrs warranty repair. But you probably have to cover the one way shipping only.

HP w22 Monitor display disappears after about 2


bill, if monitor not covered by warranty, the check out YOUTUBE for long 8-12 minute video clips of LCD monitor disassembly or LCD monitor repair to find out what the major cause of your monitors SYMPTOM that you described above. Here is a small hint for you. If you didn't see the displayed data on the BLACK lcd panel with the flashlight "trick" then you would know that the entire "switch-mode-power-supply" was in complete SHUTDOWN mode or even blown the "line-in fuse" for the monitor. Also try a visit to www. ccl-la.com/badcaps.htm and view some of their vids on repair of lcd SMPS/INVERTER supplys and cold-cathode-fluorescent-lamp replacement. They also do the repairs and return shipping. Please rate this on fixya if this response was helpful. Bye for now. 12fixlouie

You might wanna check your HP w22 system

Try replacing your ram with a new one or any working one

if your ram is in good condition then check your motherboard if you dont know how to trouble shoot a mother the best way to go about is to use a new one or any working one compatible to your system

Screen image appears fuzzy, jumpy and broken up into lines.


gardenman13, I would certainly complain to HP about their w22 monitor!! Find out if the units warranty is still valid and can be swapped-out for a REFURBISHED unit. Your w22 shouldn't be hazy, distorted, or flicker for any reason. My best guess is that it (w22) has problems inside with it's "cold-cathode-fluorescent-lamps" and electronic ballast circuit called an INVERTER circuit, which could also cause the main "switch-mode-power-supply" to go a little NUTS upon STARTUP!! FYI you are dealing with a technology similar to the curlie-Q CFL screw-in light bulbs. Their ballast's are called CONVERTERs (ac to ac) and are cheaper. Your lanps are thinner and straight, hung on rear of your LCD panel. I hope this was informative. Please rate this on fixya. 12fixlouie
