How do i know when

The image will begin to fade and become harder to see. If you then try adjusting the brightness higher and it doesn't make much difference, this will confirm a bulb replacement issue.

Mitsubishi WS-65907 rear projection TV HD goes blue.

I would look at the source for the Hd signal as being the problem--if you are using some kind of cable or sat box it will deliver the signal to the DTV input on the back of the set--this is the HD input for this set.

It is possible to have a problem like you describe be one in the set--but very unlikely----have you looked on that green signal board for any signs of Glycol?

Anything that will produce a 1080 signal to the DTV input should tell you if the problem is the set or the source of the HD signal that is causing the problem.


If you have questions or need advice let me know--I am here to help people.

Mitsubishi WS-65807 blinks '22'

I replaced the pico fuses and the convergence IC's. fuses poped right away code 22 . Further inspection of the board showed the coolant had leaked out of the center projector and fried the board. Not willing to pay $300. Passed it on to someone else

Convergence problem

You will either need to order a new convergence board or a STK chip to replace the bad one. STK chips require using a soldering iron. A handy guide for this repair can be found by clicking on the link below. Best of luck and hope this answers your question.

Mitsubishi WX-65907 picture with sin waves

In the past I have replaced the filter caps in the power supply and it has solved this issue in other similar models in the Australian consumer market. If your keen to open the unit up and examine the electrolytic capacitors they ones that bulge on the top and somtimes leak are faulty. The picture below is a classic example of this:

Location of temperature sensor on Mitsubishi WS-65907

bendake,
It's been a little over a month, since your post, hopefully you have your problem resolved. If not, perhaps I can help. I'll call my response a SWAG rather than a WAG, so I hope it's helpful to you. First of all, let me answer your question, I'm not aware of any temperature sensor in that model. Less than 2 months ago I got a WS-65907 with a power problem. When I turned the TV on, the green power on light would come on for a few seconds then it would go off. The problem was a couple of pico fuses (5amp) and the convergence IC's. One of the IC's was shorted and that's what was blowing the fuses. Anyway, the IC's run hot, they are on a large heatsink. You may be able to purchase some thermal paste from Radio Shack, etc and put it on the back of your IC to help dissipate the heat. It's good that you're getting a 1-2 error code which indicates no error detected. In my research on the Internet, I read that Mitsubishi didn't put enough of the themal compound on the back of the chips and that's what caused them to eventually go bad.
If you've removed the front panel (and you can see past the neck of the 3 tubes) you should be able to see the vicinity of the IC's. they are located on the Middle board, they are attached to a metal heat sink (approx 4"X 8") the IC chips have a narrow metal strip holding them onto the heat sink. You may also consider getting some freeze spray that can be put on electronics. It may be useful in determining if this is your problem area. If so, you may luck out by applying some paste to increase the thermal transfer and keep the chips running cooler. Good luck with your TV.

Coolant leaked from the green bulb

Yes, the diagnosis was correct. Some models of Mitsubishi as well as a few other manufacturers have had issues with this. The cost to replace circuit board damaged by the coolant (ethylene glycol) along with the affected CRT is prohibitive. Check with Mitsubishi. Some manufacturers acknowledge problems such as this and may offer assistance.

Mitsubishi ws-65907

I had the same problem with my WS65907. If you know a little about electronics and how to solder, you can fix this yourself. First you're going to have to carefully remove the PC board from the TV. There are four "pico" fuses located by the regulator. check the ohms across each one. I found two of mine were "open". I replaced them for $1.49 Ea.
