Question about Mitsubishi WD-57833 57" HDTV
I took out the color wheel & was told that the wheel was good. it was just a bad bulb... after putting everything back together that's when my problem started. tv came on but only white screen with black 3 inch lines... what did i do
You'll need to check all the connectors that you unplugged, make sure they are plugged in to the correct place, plugged in well and no pins bent over etc, Probably should also check any connectors that you did not have to unplug just to make sure they didn't get pulled while you were getting to the color wheel.

After 11 years???? OMG This set is a tired pup and should be put to reast. My experience with older sets and your complains are all capacitor problems and is only gonna get worse as the first time around repair will take several capacitors to repair. This set has no user serviceable parts inside so you should not attempt a repair suchj as this on your own.. This repair if you decide to go through the first time will be About 300 to 600 bucks the first time and cost will continue to raise till the sets put to sleep. Good luck

I don't know of illustrated instructions but I can provide you with the service manual for your TV. It does have illustrations of disassembly and components as well as schematics. Your set very likely needs new convergence IC chips. This is a common problem with all projection TVs. The repair is not expensive ($60-75 in parts) but does involve unsoldering and removing the old chips and soldering in new ones. Some times there are some fuses that need to be replaced as well. If you want the manual provide me with an email address.

Hi,it definetely sounds like the color wheel.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Found your color wheel here: http://www.discount-merchant.com/MITSUBISHI-00-L3603-002-p/1162430.htm Have a bless one!
