Default I'd Love to Laugh at your Problem, Only I'm Facing the Same one...

My dad is a Korean War Vet in declining health. I figure, he's got about 1-2 years left in him. His beloved Mitsubishi 73" colour TV has just turned hip & trendy---it only plays French Noir movies from the early 40s (E.G. It plays colour for about 40 minutes and then goes into a hideous Black & White and wavvy mode---hence the French Noir reference).

The man came out and said 'Yer Light Engine---ain't' $700.00!!!
Pop wants an 80" Sharp TV but the salesman who sells both Sharp & Mitsui says, given my parameters of my dad's projected longivety vrs the cost of buying a NEW 80" TV, it would be better to FIX it.

1. The Mitsui 73" was top of the line when we bought it. It operates at 240hZs which is faster than Sharp's new 80"er.
2. Spend the $700.00 and get his TV back on line
3. Worse case scenario, you have a tube go out. Tubes are like $100.00 each and it would be RARE if more than two would go out in 5 years. Tubes are a piece of cake to replace---unscrew off back, twist receptical, remove, insert, twist & replace back.
4. $700 + 200 = <$1K for a 5 year investment ($200.00 year)
5. At $6k for a 80" Sharp---I'd be lookin at more than $200.00 a year JUST IN INTEREST PAYMENTS on the $6K for a TV that's bigger but not better (the chip in the Sharp is slower than the on in my Mitsui)
6. Am I smart or am I throwing good money after bad
7. What cha think?

Recent update.....

A Mitsu authorized service tech came out and diagnosed it with a bad light engine. As long as I can come up with a purchase reciept it will be covered under warranty. If not, it's about a $700 repair bill. After it gets fixed, I'm taking bets as to how long it might last till the light engine needs to be fixed again or another bulb goes out. Any takers???

Maybe I will just sell it while its working, and purchase something else. I like the idea of a large screen. Do any other manufactures make anything bigger than a 65" screen that would be of any quality?



Thanks

If your good with tools and can take out he light engine yourself you can fix the mitsubishi yourself for 100.00. See ebay post above.

That will fix that tvs color issue. If u have any questions pm me and i can help you.

Default My WD73727 does not seem the same problem, but maybe?

Mitsu 73 has great color for about 30 minutes to an our, degrades to the splotchy coloration, then eventually falls into discoloration and flashing. Mine however does not shut down or error out...flashing indicators on front of TV panel.

However, if I let it cool down for a while, it goes back to great color and restarts that 30-40 minute downspiral. Does this sound like it's overhearting, or is this typical of a bad color wheel sensor? I can upload pix if anybody interested in taking a guess...

It does sound like the color wheel sensor. If it cools down and can turn it back on and its ok for a min it is.

It will get worse before it gets better.

I have the sensors.

Default Thanks Brad. This helps.

I'll get with you on replacing the sensor. This part, looks like it requires no welding? Sorta plug and play onto the wheel itself...

Since I am getting no shutdown or flashing messages at this point, is it safe to assume that the set itself is not overheating?

Yea theres a sensor behind the lamp houseing that will shut the unit down if it does in fact over heat. It will get worse with time. The 30-40 mins u get now will eventually just turn on like that.
