Two possibilities : tape guide mechanism in the VTR needs replacing/adjustment or more likely CCD sensor is outputting a 'noisy' image and the CCD sensor block must be replaced. Many manufacturers of v-cams will repair this fault ( CCD sensor ) free of charge. Find out.

Most likely you are looking at a defective LCD panel, but I would recommend getting a proper diagnosis.

Hey I got an IBM T42. It boots fine when its clear but after that it horizontal lines being to appear througout the scree.


Hi,

Either you can hook up an external monitor or access BIOS setup (Basic Input/Output System) to replicate if the horizontal line appears. This step will check if the problem is with the video card or the LCD.

If you get the horizontal line on the BIOS or never get it on the external monitor, then surely the LCD screen is beginning to fail. You need to reinsert and/or replace the LCD inverter or LCD itself.

However, if you see the horizontal lines on the external monitor but not on the BIOS, try to update the video driver. If this will not resolve the issue, you need to replace the video card or the motherboard of your laptop.

Hope this helps.

Hello. Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen). It looks like your next step is to replace your TV.

My screen is blue when ever i change my batteries, So I Press the 2nd button and make it lighter. But the pixels dont lighten all the way And when i go to some type of menu like for Zoom, there are...


Try to reset everything to see if that helps. If it doesn't , you can try to upgrade your operating system on the calculator to see if that helps to make it go away.
If that doesn't help try this:
"Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message."
Let me know how it goes.

LCD screen not working


Try a hard reset first. Remove batteries for about 10 minutes and reinsert fresh ones. If the lines still appear, there is a problem with the LCD screen. Contact Logitech support for an RMA.
