Hi guys,
I have a gateway computer. My problem is that the monitor does not display anything when I switch the computer on, even when the LCD indicator is on. It all started when the display started getting shaky and warped, threatening to switch off. I then switched off the computer and then back on again-the monitor came on (at least the indicator was on) but no display. Is this monitor dead? The computer still works properly-I can still play music and switch the computer off using the keyboard keys (not the mouse). Can someone please help.

Regards

’s high-level point about the fault being either in the display chain or the PC hardware is on target. The symptom you described — the panel was “shaky and warped” then went dark while the monitor’s power LED stays lit but no picture appears — gives a few specific, practical checks to narrow it down quickly.

  • Shine a bright flashlight close to the screen while the PC is on and look for a very faint image (desktop or boot text). If you can see an image only with a flashlight, the LCD panel itself is fine but the backlight/inverter (or inverter wiring) has failed.
  • Press the monitor’s OSD/menu buttons. If the on‑screen menu appears (or its LED blinks), the panel electronics are at least partly alive and the problem is likely the backlight or input detection. If the menu never appears, that points more to the monitor’s internal power board or mainboard.
  • Inspect cables and connectors (power and video): look for bent pins, loose screws, or a failing external power brick. Wiggle the cable gently with the PC powered on to see if the image returns intermittently.
  • From the PC side: listen for BIOS beep codes at startup, watch keyboard LEDs during boot, and try the other video outputs on the machine (if present) — these checks help confirm whether the GPU/motherboard is producing any video signal.

Given the earlier “warping” behavior, capacitor or inverter failure inside the monitor is a common cause. Opening an LCD contains dangerous voltages (inverter/CCFL) — avoid DIY repairs unless experienced. If the monitor is under warranty, contact Gateway; otherwise replacement is often cheaper than repair for older LCDs. If the above checks don’t isolate it, a shop can confirm whether the fault is the panel/backlight, the monitor power board, or the PC’s video output.

Test the monitor on a nother computer, if it doenst work then its your monitor. If it does work then it is most likely something wrong with your video card, or if you dont have a video card, then your motherboard.
