If i switched on my pc, for the first 5 minutes it is working normally as usual. but after that, some grains like in tv , it appears. after that some fluctuations occurs with the colour black and white images.then, the whole display disappears.
no problem in video ,or power.
i have checked that by replacing with my friend's monitor , it is working as normal. so , wat my thought is the problem is with the monitor , or data cable or inside the circuit .... i m sure that it is not with the cpu

1. Check your power cord & adapter. 2. If its working then check the battery, reseat the battery & check. 3. If available then check with another battery 4. If no, then remove the battery & switch on the PC in AC mode. 5. Check if battery charging indication or AC power on indication is glowing. if not then need to change ur motherboard. 6. If indication is OK, but could not power ON then check ur RAM for any loose connection or dust. clean & reinstall. 7. If still no display, connect an external monitor, check if display is comming. 8. If Display is coming then your LCD need to replace.
There are many things that could be causing that, but to fix it would take some electronic equipment, schematic, and know-how. It could be as simple as a faulty potentiomet, but a shop would charge you more than it's worth to fix it. My advice is to live with it until it gets too bad, and invest in a new one If you're not ready to advance to the LCD monitors yet, check with a Used Computer Store- they usually have CRT monitors at a reasonable price. Hope this helps.
Please check whether the monitor is set to the correct settings. If you feel its incorrect, most LCD/TFT monitors come with an auto set up button which will restore the display to one that usually works. In case it still doesnt work, you might need to connect your pc to a different monitor and check the display settings. You could also try to download the drivers for this monitor and then re-connect the monitor and see if it works.
tricky!! oh hi im Dyanne.. a totally unresponsive black screen can be th result of failure of th LCD or LCD inverter.( a specialized piece of electronics that energize th screen) to rule out th failure of th video display adapter or circuitry, try plugging in an external monitor..a standard pc monitor.. attached direct to th lappy. if it works, (as i susopect) th motherboard and video display are both working ok and its th LCD which is at fault. this can sometimes be repaired by a competent specialist. good luck xx
Repairing the DELL E171Fpc LCD Monitor with the complaint of display shutdown after few seconds (power LED still on) was not difficult. Normally when this type of problem happens, we would first suspect the inverter board, then the filter capacitors and lastly the main board.
A defective in one of the lamps and a faulty TL1451AC PWM IC or inverter ic may caused the display to shutdown as well. If the lamp is defective, it will send a feedback to pin 3 or 14 of TL1451AC IC and caused it to stop producing output signal thus the display just shut off once you switch it on.
