You could try changing the twelve 1000uf/16vdc caps. four on each of the power supply, FMT, and DM boards. this may take care of it.
most likely though the chassis needs to be rebuilt. check out www.tv-texhs.com

The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.

If the green front panel LED blinks continuously and the TV never comes on, its an issue with the "DM" board. When these TVs are first plugged in, the green LED should blink for 30 sec. to a minute or so. This is the TV booting up, reading its software. Mitsubishi has been having problems with this circuit for several years. In may cases the only permanent solution is to have the chassis rebuilt by Mitsubishi at considerable cost and inconvience. The chassis may have to be sent back to Mits for this rebuild. Call Mits and ask for help.

this problem is either a power problem or bad projection lamp problem;
How long have you been using this TV and have you ever changed the lamp?
This problem also has a symptom of a bad or dying projection lamp and sometimes the ballast board. The ballast board helps to ignite the projection lamp.
So, you might need to replace the projection lamp and if possible, ballast board.
Again, the constant blinking light also be caused by failed capacitors on the DM power board. Check the below link, you will find the service or repair manual for your TV.
Also, to order for a repair kit to fix DM board problems, visit; http://www.tvrepairworld.com/mitsubishi_repair_kits
Check the above two discussed as one certainly has to be the cause of the problem.
