Question about HP L1706 17" LCD Monitor

1 Answer

I have the same problem. "No Input Signal"

I am using an HP L1706 monitor... This issue happens at random times but I was able to fix them just by turning off my computer and for some reason when I check the back of the tower... reconnect and disconnect the VGA cable it'll work. But last night the problem happened again. I tried to do the same thing and it is still not working. Thinking that it's not the monitor or the VGA cable that's causing the problem I tried to connect my SAMSUNG SyncMaster 753 DFX monitor using also a different VGA cable. Still the same problem happened.

It might be the tower itself that's causing the problem. I've noticed that the motherboard's green LED is not lit. Though theres is power because all the fans are working. Even the GeForce 9500 GT fan is working.

Can it be the motherboard??? I'm using a FOXCONN G31MV Series motherboard, 4GB RAM, Core 2 Duo processor, 250GB SATA HDD, and a GEFORCE 9500GT video card.

My monitor HP L1706 does not ignite but the green light blinks

Your screen is in sleep mode.
Its does not receive a signal from the pc.
Check for loose connections or a damaged cable.

Your monitor could also have a defect internal.
Maybe also your graphic card in the pc.

Good luck.

HP L1706 vertical lines

Check that the connection from the graphics card to the monitor is good and that the graphics card itself is in working condition by testing the computer on another monitor.

If the problem persists, the issue is with the monitor and possibly a connection to the display internally which will require a competent electrician to check out

L1706 monitor power light flashes green/amber

A flashing power light often means the monitor isn't getting a signal. When you turn the monitor off and back on, do you see the brand logo for a few seconds? Try plugging it into a different computer to see if it comes on.

If plugging it into another computer doesn't work, it may be a bad power circuit in the monitor. A common problem with monitors is the capacitors going bad. If you're handy with a soldering iron, you can try replacing them yourself. Look here for pictures and instructions: Fix an LCD Monitor
