    Hi,

    thanks for the advice. I took the back off and checked all the connectors that I could find without getting into the 'guts'. I paid particular attention to the circuit board with multiple plugs that I felt might be the main board for the screen.I also vacuumed all over the boards etc. Unfortunately the blue line is still present on this t.v. so that didn't work. Very much appreciate the advice though and enjoyed 'getting stuck in' : )

    So is it likely to be the screen or a circuit board. Any idea how much? Are the parts easily available?



    NB I don't think it's a 'projection television' just a LCD HD TV

    Thanks Dan,

    I'll probably live with it as the TV was bought at auction 'sold as seen' but wasn't switched on at the auction rooms and had a large sticky area on the screen.This was due to an old sheet of protector being left on. The plastic came off easily. This obviously put buyers off as the TV cost £6 UK or $9 inc taxes !! at that price I would be impressed if the viewing area was a thin line and the rest of the 25.99 inches was blue : )

    Thanks again

This can be an indication of a defective LCD panel or just a bad connection to the panel. If the unit is no longer under warranty, open up the back and reseat all of the cables and connectors. Sometimes because of the extremely low level of the signals that are inside the unit, a little dust or dirt can make a questionable connection fail. Update this with your results. If the unit is still under warranty, request warranty service.

    It is not a projection, just an LCD. Unfortunately there is no way to determine whether the problem is a logic one or the panel itself. My experience suggests that it is the panel. If so, the replacement panel could easily cost almost as much as a replacement set. Check around in the area for a service shop that works on your make of set and get an estimate on the panel cost.

The screen is blue with vertical dotted white moving lines ... menu options are psycodelic in color


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

I hope this will help in solving the problem, and do take care in handling the problem....

I have a vertical blue line....left of center


If it is narrow you have a dead pixel problem. If so contact HP for advice. Three year warranty on screens and they usually swap out for failures. Very common problem.

40 inch lcd blue line vertical


The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!
