Having problems with your NEC LCD1712 17" Flat Panel LCD Monitor ?

LCD Monitor picture cutting out occasionally.

\015 I run two monitors, a CRT and this LCD which is the problem. This problem just started today, after about 30 minutes of the monitor being turned on the LCD screen will go blank. The power light on the LCD remains lit, and I can restore the picture to my LCD by power cycling it, but after a short (5-10min) amount of time the picture will go out again. Is there anything I can do to fix this? I've already tired cleaning out the dust by blowing compressed air into the vents as I feel it might be an overheating problem but this did not solve my problem.\015

Answers :

Your CCFLs might be going bad. CCFL stands for \015\012Cold cathode fluorescent lamps. These are the lamps that provide backlight for the LCD Monitor.\015\012These lamps do not last forever, and are a very common part to go bad.\015\012The circuit that provides the power for the CCFL is called the\015\012inverter, it might be going bad, but I still think it is the CCFL. Only\015\012trained techs should try and replace a CCFL or fix an Inverter. CCFLs\015\012do contain mercury, but only small amounts.

Since the monitor works for a few minutes and then goes dark, this tells me you have a problem with the backlight function. I have seen this several times, and I do work on LCD monitors professionally.

My advice, get a new LCD monitor and sell your bad one on ebay.
