Hi Charlene,

please try with video input from any device,and i think you are using local antenna and it has gain problem or your tuner section of the tv is not working correctly.
if distroted pictures comes with video input signal it is video amp and processing unit problem.
you have to go for repair shop for fix that.

Just bought a acer h7531d dlp projector. From the first run, it shows vertical white lines even without a video source and these lines seem to drop a shadow on the video. Is this a serious issue? Didnt...


I have found that it has something to do with the ribbon between the controls and the motherboard. I had white lines which I can make come and go by adjusting the ribbon. I still have fine black line.

I just unhooked the motherboard and reseated it. Now the projector is working 100% correctly. I have not closed the case yet. It'll probably glitch on me when I do. So in my estimation it isn't that any one part is bad but rather that there are faulty connections. Getting all cable seated properly should be the fix.

It is all together and working perfectly.

Mitsubishi rearTV has intermittent wavy lines running throughout


Do you have anything to test it in 1080i? Does it do it on all connections or just one? I had a similar problem with my TV that turned out to be a bad input board. Mine would only display 1080i through the Component connections. All others would show pink and green wavy lines. It cost me around 500 to fix it. Unplug the TV. Remove the back cover for the TV. Using a NON-metal object, or gloves, wiggle the input board (that has all the video connections on it) slowly back and forth and see if the problem comes and goes. You will have to have someone watching for you. If something is loose on that board, the problem should show itself. Narrowing down the problem will probably save you money on repair bills.

Line pink and green


this would definitely won't be the lamp, the issue is either with you video board or the dmd board, go to the menu and if that line still shows up on the menu, the issue will be with your dmd board, on the contrary the issue would be with your digital video board
