Re: Red Lines

Can you bring up the menu and see the menu over the red lines? Does the menu have red lines over it? I suspect the light engine is bad. Might want someone with experience to tackle that problem.

I have a Mitsubishi WD-62525. In general the picture is great from all sources (cable, component, and hdmi). However, there occasionally are very thin, horizontal lines that flicker across the screen....

I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.

I have a KF-42E200A Sony Bravia LCD tv. Recently we had to replace the lamp. Since then a horizontal line appeared at the top of the screen and it has grown to about 3 inches now. The picture itself is...

The lenses in the TV are more than likely misaligned due to heat from lamp. The heat can cause the lenses to move and the red shaded horizontal line appears over time because the lenses fall out of alignment.

You just need to have the lenses realigned and the red shading will go away.

My screen have some red lines

I will assume from you description that this is a rear projection crt(picture tube) tv. if this is true I have good news/bad news.
faint red horizontal bowed lines in the picture indicate the screen(G2) voltage for the red tube is too high.Slight lowering of the G2 adjustment will eliminate these lines. I stress SLIGHT because too much adjustment will mess up the gray scale .
The bad news the red crt made be bad. if the adjustment works but in the future the problem reappears then suspect the red crt replacement is probably not economical to repair.

Red Bowed Lines / Red Hue

I tried the solution that was posted for this problem and it worked!
Just remove the Low front panel by removing the two bottom screws that are covered by two screw covers, then remove the second panel (black) by removing the 4 screws then you'll notice a module with 6 adjustment knobs, get a small screw driver, and with the t.v. on, being carefull , and with somebody accross the room looking at the screen begin with the lower left knob and turn left very slowly and ask the person across the room to let you know if the screen is better or not, after this I had to adjust the green as well so, I adjusted the next knob over to the left. Do this adjustment carefully and try to remenber the original position of the knobs in case you have to go back.f
Good Luck,

Hitachi Rear Projection TV Flickers Red

No, this could mean a loose connection on crt board(red of course) Look also and check to see if lines going to board are connected correctly. If nothing, then there could be something trying to short itself out on crt board. look for burnt resistors and bad capacitors.
