Question about Mitsubishi WD-65735 Television
There were white and black spots all over the screen of my TV. I had read previously on the web that this was caused by dirt on the mirrors. I removed the cover but the mirrors were clean. Believing the spots to be on the lamp, I removed the lamp. The lamp was also clean so I removed the engine assembly. Unable to find the cause I put the television back together. When I turned the TV back on I had two black horizontal lines of lost information and white vertical lines every inch across the TV. And the spots were still there even in the areas of lost information. I later found that the spots were caused by a bad DLP chip. What did I do to my television and how do I fix it?
It is your dlp chip i just changed mine make sure it is in tight ther is a video on you tube that is very helpful mine did the same thing with the lines untill i got the dlp chip in tight

Hi,all HDTV have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board and also white spots.
A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but the bar is gone. The same will happen if the chip that outputs to that area opens.
The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them.

It's either mirror hinge fatigue or dust on the inside.
Mirror hinge fatigue can be fixed by putting a solid color picture (white or gray works best from what I understand) on the display and letting it sit for 20 minutes.
If it's dust, someone is going to have to go in there and clean it out.
Also could be a defective micromirror device.
Try the first suggestion and if it doesn't work, you're going to need a technician to take a look at it.
