Mitsubishi Diamond WD-65831 65" Projection HDTV - Page 3 - Answered Questions & Fixed issues

check the lamp

the dark lines could be what is called hum bars these are caused by ground differences between cable and your AC ground. check to see if these lines appear using a dvd and removing the cable from the cable box. if the lines disappear then call the cable company and your electricain. in the mean time you can use a plug adaptor that is the 2 prong (ground less) until you can have the problem fixed. but don't use the adaptor as a fix, for your TV is a computer and needs proper grounds.

suspect the optical engine. are they present after initial turn off before the blinking light comes on and the cooling process starts? if so then it will be optical engine issue. can be very pricey by the way

sounds like the projector globe is gone. i think you will need to replace it. if you are lucky there should be a pannel on the side or rear of the tv that allows you to replace the globe. pricey though.

good luck

Check to see if the lamp is on when the unit is off (in standby) if it is components on the Power PWB... 9A20 and/or K9A21 are shorted. Also, R9A02 may be open.

Have you checked DLP termistor?

Basing the replacement of the board on the clicking sound of a relay trying to close is not a safe bet. The first thing you need to do is check the bulb. Then there is a ballast board and then the Power supply board. Parts might be hard to find. Use the website I listed to see what part numbers are then google it or look on eba or amazon for those parts. Mitsubishi WD 60C8 TV Parts

Most likely a fuse blew when the lamp blew, there is internal fuses on the power supply board on these mitsubishi's, if the fuse is ok though then most likely another component somewhere failed.

Replace your lamp. Make sure its a real Osram bulb and not some cheap knock off. These folks have Osram bulbs and a 6mo warranty. Projector Lamps and TV Lampson Sale ProjectorLamps com stocks Superior...

If your set worked well (no lines, maybe only white or black scattered pixels) before you replaced the DLP chip, then your problem could be that the DLP chip did not get seated properly or the cam screws were not tightened enough after replacing the chip. The DLP chip must be seated properly in its socket or else line and column lines will be seen. There is also the possibility that the DLP chip is defective or suffered static damage while being handled during the installation. Hope this helps.

Hello. There are three places smudges that are seen in the picture can be found on a projection TV, the lens, the screen, and most likely, the mirror, but none can be discounted. All three can be accessed by removing the bezel and screen assembly. Most of the screws are around the edges from the back, and some are under the flap that hides the front controls. Good luck!

Hello. I have replaced many DLP chips, as I work for a repair shop. I have seen similar symptoms when the chip isn't seated properly in the mount. There is a gray screw that should be loosened to remove the chip, and tightened when the new one is installed. Most importantly, you must make sure that the chip is seated flat in the socket before tightening the gray screw. Since you have done it once, you should have no problem correcting the issue! ??

Hi, if you power your TV on and see a black or grey screen, it may be on the incorrect input. Inputs get changed when switching the TV input for dvds or video game consoles. Look for a Source or TV Video button on your TV remote, not the cable remote. Before doing this, please make sure all connections are secure. I hope this helps or reply with more questions.

sounds as if you may need to degauss (remove residual magnetic field) your set, such magnetism can cause the final image to become distorted. many televisions have a degauss utility in their menues

TV codes, if any, for universal remotes are gotten from the manufacturer of the remote.

Hello, count the blinking light pattern. It may blink 2 to 9 times, pause and repeat the pattern again. Does it ever light the screen when it's cycling on and off? Let me know....tks
