Question about Televison & Video
So, I bought this WD-73727 Mitsubishi 73 inch DLP off of some guy on Craigslist that was moving out of state for $375. He wanted $700 for it, but when I showed up and plugged it in it did not work. The l.e.d. on the front of the TV indicated it had a bad bulb. I ended up talking him down to $375 since I had to buy a bulb, and we made the deal. He told me that he had owned it for two years, and had no problems with it other than having to replace the lamp once. He said he really liked the TV, but could not take it with him, so he had to sell it.
I got the TV home thinking I had just made a slammer deal. I was going to purchase a bulb, and was going to watch the Super bowl on a 73 inch TV!! I purchased a new bulb ($200) in town, and installed it. I powered the set up; bulb seems to be working great...... but minor problem, the whole TV flickers! It seems to only have blue and green colors coming and going on random parts of the screen while it appears the screen is split down the middle, while independently jumbling, glitching, and flickering.
I can bring up all of the menu options, and see them, but it is difficult to look at the screen because of it flickering so much, almost like a strobe light. I hooked up all inputs with the same results. everything played, but the screen flickers with the color all screwed up.
I found nothing in the owner's manual that would help, so got on the net and started researching. I downloaded the service manual. I went through all of the troubleshooting procedures and nothing. When attempting to get an error code, it just flashes #12, (nothing wrong). So,
I replaced the lamp (part#9159027010), but that wasn’t the problem. The TV still flickers with messed up color.
After reading multiple posts in multiple forums, I have tried everything. I have re-seated the dvi cable going to the light (optical) engine with no good results. I have done manual hard resets on the TV. At this point the problem is looking more and more like a light engine problem. Unfortunately, I cannot find anywhere on the net that has the part # 938P019010 in stock. I have no problem fixing this myself, but need access to the part. Do you know where I could get one? Do you think something else on the TV may be at fault? after the new bulb, I now have a $575 paperweight, and am starting to think I took a bad gamble trying to fix this thing. I have no problem putting some money into the set, but man....I'm getting closer and closer to the cost of a brand new 73'' DLP.
Do you think I have a shot at getting Mitsubishi to repair it for free since they lengthened the warranty on the sets for defective light engines? The manufacture date on the TV was Oct. 2006. So I am hoping it was not purchased till early to mid 2007. However, since I purchased it second hand I do not have a receipt. Would this be a problem? I have written the guy I purchased it from to get the receipt, and he is trying to find it with no luck yet.
Please help.......any suggestions? Am I on the right track? Is this a lost cause? Will my dreams of having a 73'' TV in my living room die? Please help.

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00

SOURCE: Samsung DLP Flickering
If you're certain the lamp is good, it's probably the ballast. The ballast has enough juice to power the lamp, but it's unable to maintain a steady consistent level of power, hence the lamp flickering. Changing the lamp may temporarily resolve it because a new lamp is more easily maintained than an older one, but if the ballast is failing, the problem will recur and probably shorten the life of the lamp. The ballasts cost around $70-80. Replacing it can be done by the electronically adept end user, or you may need a service tech. The problem with a service tech is that some may not acknowledge that the problem is the ballast especially if the intermittent flicker is not happening while he/she is examining it.
