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 haveMy compaq presario CQ40 and my monitor screen got flicker always for past few days and more red horizantal lines @bottom of the screen, where i couldn't see the data,time,date... Plz help me...


This is usually a sign of either a bad LCD screen cable, a bad LCD screen, or a bad display adapter.
If you connect an external monitor & you get a picture without these red horizontal lines, then your display adapter is OK.
Diagnosing a bad LCD screen cable or a bad LCD screen requires that you disassemble the LCD screen panel, & swap them one at a time with a matching part. This way you can identify which part is causing the problem & replace it.

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.

Sounds like the red picture tube could be shorting internally which would cause the "all red" condition. In which case you'd have to replace the red tube. Are there horizontal (slightly slanted) lines through the picture as well when this is happening and a very very bright screen? If so it's most likely the tube.

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,
Californian.

Send it in for a quote. It should cost the equivalent of $10 USD, more or less, wherever you are. No expert, however talented, can bring a broken sensor back to original shape.
