Question about Computer Monitors

1 Answer

I saw you answer a question about LCD screens going out

My Aopens screen comes on for 3 seconds before going out but the monitor stays powered on, I have my Inverter/Power board remove from it quite certain this is the cause but cannot find a replacement board anywhere. I've searched and searched and have attempted to contact AOpen multiple times with no luck and cant seem to find this board anywhere.

I was hoping maybe you knew somewhere to find one. The model on the board itself is JT198AP 2202126501. 

Thanks!

Power button is on (blue) but no display. If you


Try to change the screen resolution and frequency setting of your graphic card.
1. Restart your PC
2. Before getting into splash screen, press F8 frequently
Choose enable VGA mode by pressing up arrow and press Enter, wait until finish loading. Now the display looks bigger, change the screen resolution to best fit to your Monitor (normally 1360X800). DO NOT CLICK OK>go to advance tab> Monitor tab, choose 60Hz for screen refresh rate, NOW you may KLIK OK

Hannspree HF229H will not stay on


railbird56, Common problem for ALL BRANDS of "cold-cahtode-fluorescent-lamp" back-lit lcd monitors! Here are your options!!! Cheapest to most costly!! 1. Warranty repair. 2 DIY repair???? 3. Local or distant repair. 4. possible old + cash swapout with Hannspree for refurbished same model?? 5. Trade-in for new wide screen. My best guess on your monitor (no history) is that the unit's SMPS is in partial or full shutdown mode during it's black screen moments. How much do you know about "electronic ballasts" "switch-mode-power-supplys" and how to repair them?? 12fixlouie

Proview Monitor Blank display after 3 seconds issue


First place to look will be the power supply section, look for bad caps (bulging tops or bottom seals), the post back what you see so we can guide you further for direction such as voltage checking, see example of failed monitors due to bead caps: http://s807.photobucket.com/home/budm/allalbums

Samsung 931B Monitor Screen will not stay


jane657, Hi there. Will you stop pushing the On/Off button on your lcd/fpd. It's Broke. Period. End. Finito!!! You will not fix it. However there is one test that you should do to determine hoe bad the problem is. You will need to reconnect the 931B to a known good pc that has been fully booted and has the WIN-DESKTOP or IE fixya web page showing. quickly connect the931B to the wall outlet and the PC. Turn on the monitor!!! Yes, I know it will only come on for a second..After the screen goes to BLACK, Shine a bright flashlight onto the screen at different angles, 1-2 inches from the screen. Let me know if you see something even though the screen is black. Anyway here are your options as a consumer/user. 1. Check if unit is under warranty. 2. Check withh Samsung to see if they have a SWAPOUT program. You send them your monitor+$40-$90 and they return a refurbished same model to you with a 30 day warranty. 3. Trade in for new monitor. 4. Check with local TV/Monitor repair guy who knows all there is to know about cold-cathode-fluorescent-tubes, their power-source(inverter type) and lcd monitor power supplys (SMPS) 5. Repair on your own. Not recommended for amatures with no solid state troubleshooting skills and no instrumentation for support. Bye for now. I'm louie12fix on fixya or lmistyrel@ aim.com

I just repaired one.... will likely require that you replace 3 X 220 uf 25 volt capactiros and 2 X 1000 uf 25 volt capacitors. can't miss them the tops are swelled up. but the monitor appears to work now... not bad for 5 bucks worth of parts.

Gateway Monitor FPD1760


Power light coming on when you plug it in but no lighting of the screen is usually caused by the power inverter board having gone bad. Common on the 17s due to their age is a bad bulb or more.
I repair these 90% of the time

Monitor only stays on for 3 seconds


There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.
