Question about GVision J7PH 17.1 in. Flat Panel LCD Monitor

1 Answer

Monitor is shutting off after a two seconds

I have a j7ph-ta 17.1 Touch Screen I bought for $10 because when you hook it up it will come on full and clear for two seconds, beep then turn black. The green light is indicating that it is on and has a signal is still on. If you turn it off and then back on then it will do the same thing again.

I have tried:
Changing resolution down to 800x600
Changing the refresh rate in windows
Several computers; all the same reaction
Installing drivers for the touch function while

So I don't know where else to start with the troubleshooting. Any ideas?

What is the make and model and type of the monitor? Is it an LCD type, an LED type, or a CRT (cathode ray tube) type, which looks like an old picture tube?

SOURCE: Problem with my LG monitor L194WT

First change the referesh rate for your monitor. If that works, then you dont have to change the resolution. If that does not work, try increasing the rate again. Once you can get the game, then try to change the resolution from within the game options, if necessary..

SOURCE: Many screens on one monitor!

Your monitor is malfunctioning and requires servicing. Unfortunately there is no software solution, and no monitor adjustment buttons will control this problem. Due to the high cost of replacement parts and service technicians, it may be more cost effective to buy a new LCD monitor. Sorry to be the bearer of bad news :(

SOURCE: Had the blank screen problem. Now it won't work above 800x600 res

The case is a PITA to pop apart, I use plastic Guitar pics to release the latches to separate the case, this works VERY well and doesn't mar the plastic on the case seam. Patience, and don't use excessive force...

Replacing the 6 Caps fixed my monitor..

Before you start, pay close attention to the orientation of the connecting Cable between boards, it's NOT Keyed. Mine had White Bands on the connectors that faced the Chassis when the Board was mounted.

There seems to be different versions of Bords depending upon production dates.

Some of these Monitors do have:
(1) 470 uf @ 10V
(3) 470 uf @ 25V
(2) 1000 uf @10V

I replaced them with:
(4) Radio Shack 272-1030 470 uf @ 35V
(2) Radio Shack 272-1032 1000 uf @35V

$8.34 Saved an Expensive monitor.

I would prefer to use Higher Quality Caps, like the Panasonic Caps from Digikey, but this worked in a pinch. The higher Voltage should make the inverter board a little More Robust.

Good Luck

It may be that your video card is too old, that probably is the problem since you are running Windows 2k. If not open up your monitor's menu and see if you can manually change the monitor's resolution. Newer monitors do that.

Elo 17" LCD Touch screen ET1725L Powers off after 1 second

Your problem lies ion either your back light inverter or in the backlight tubes ( bulbs) which are embedded in the LCD display. The display has 4 ccf tubes inside of it that provide the backlighting. if any of these tubes are bad the backlight inverter will shut off after about 1 second. Because there are 4 of these tubes inside the screen you may not notice ( brightness wise) if 1 of them is out.

You can buy another backlight inverter( about $70.00 US) however, from my experience that would be a waste of money. Unfortunately, I think your problem probably lies in your LCD and the backlight tubes are not replaceable.

Hope this helps all who have this problem.
Good luck

It looks like your power supply is shutting down (terminal overload shutdown) due to excessive current consumption. You need to get a power supply that meets the voltage and current requirements of that monitor or greater current reuirements.

HP Pavilion dv9000z 17" Problem with monitor turning off

if you are clueless in this, better not to touch anything. The only thing you can do is reinstall the operative system, after backing up you files of course, so you will make sure the problem does not come from software. If the screen still failing you have to either repare it (which inplies disassembling) or replace it. In the first case i repeat, if you are clueless, better not to touch anything... and in the second case you should take it to an hp authorized technical service. It might be expensive but otherwise you could end up with a broken laptop.
