Attention Dave

Hello Dave,

Please see if you can help me with this issue.

I bought a compaq monitor. TFT 8000.

It has a bunch of coloured vertical lines that do not move or twitch.
they are constantly there.

The picture is perfect with the exception of the coloured lines.

Any way to fix?

Thanks

Absolutely not a repair you can undertake yourself. LCDs have plastic ribbon
cables (plastic printed wiring) with hundreds of tracks sandwiched between
the edges of the LCD layers. These ribbon cables attach to driver ICs which
address the rows and columns on the LCD. Horizontal or vertical lines are
symptomatic of the bond failing, or one or more driver ICs failing.
Sometimes they can be the result of a hairline fracture of the LCD itself.

If the glass has an invisible fracture, the LCD absolutely cannot be
repaired, it has to be replaced. Faulty driver ICs or printed wiring can be
repaired by LCD specialists, try a web search for 'LCD repair' and you might
find someone in your country who can do it, or at least give you an
estimate. The companies I've looked at use a fixed-cost system for various
repairs, eg, backlight, tab bonding, polariser replacement etc. The bad
news is that this kind of repair is really only cost effective for high end
monitors or very expensive laptop displays, I'm not familiar with the Compaq
TFT 8000, but if it's a low end monitor, forget about getting it repaired.

I just bought an AOC 19" LCD with DVI and analogue in, 4 port USB 2 hub and
audio for 350 UKP, HP charge 800 UKP for a 14" LCD replacement for their
Omnibook 6100. Absolutely disgusting, and one example of cost effective
repair vs replacement!

One more thing, generally the bigger the TFT, the bigger the fixed repair
fee.
