I don't know about nettiser's credentials, but I've found plenty of people who would disagree with his/her assessment.
The flashing green timer light after a lightning storm seems to be a very common problem with old Mistubishi rear projection TV's. A friend and I had the exact same problem.
Using this and other sites, I spent $36 bucks and a little time with a soldering iron to replace the capacitors on the DM board and got mine up and running (WS55859). I've never really worked on electronic circuit boards before, but the helpful advice at these sites got me up and running. Definitely check it out before you hire someone or replace your TV:
Repair Kit with instructional CD available at:

for under $40 plus shipping.
Discussion of process in detail at:

for the WS55859 model, which may be a little different.
And I am sure you wont like the suggestion one bit!
Blinking lights without picture and sometimes accompanied by a clicking sound( but not always) is indicative of failed Sustain boards which control video and sound.It is also possible the Power board is also involved The repair on one of these models will set you back about $400-$500 or more depending on the repairer. It is not DIY as you require an understanding of voltage testing at the circuit points on the schematic and a total reset of the convergence unit.
If you had a storm revcently it is possible that a spike caused this. You may be able to claim under FUSION in your home insurance policy/ Also in the future protect expensive electronics by incorporating an anti spike power board
Please rate my help++++Thanks for using FIXYA
Note to fedupintx
As an electronics engineer I feel it is more responsible to advise against DIY on large TV's due to High tension Voltage and radiation.
What you have to realise at "Master level" is that you have yet to come to the understanding that many of the people seeking help on this forum are not skilled Otherwise they wouldn't be asking the question necessarily.
Reading circuit diagrams, using a soldering iron, and understanding the terminology and complexity of rebuilding a damaged TV and retuning convergence is often beyond their capability. It is also downright dangerous to suggest they attempt to take on such a task. If you do some research within the forum you may also come to find that many who jumped in to do their own repair to save a few bucks are still on here for a second and third time trying to find why they still have the problem, as well as still throwing dollars at it, despite having re-soldered capacitors or swapped boards, it is not the final answer.
Why did these components that are obviously damaged stop working in the first place? Our experience shows that the obvious is not always the answer to the problem. It requires skill with multimeter and circuit diagram to ensure other areas are within tolerance and the problem is not repeated and 3 times the cost of doing it properly the first time.
It is the aim of FIXYA to have satisfied customers who receive reliable and helpful information that gets the best fix, rather than encourage gungho cowboy or board swapping jockey type approaches to their problem.
Yes you may have been able to do your own with a kit and CD, but is does not mean that all who take your advise can achieve that goal, or that the problem presented is as vanilla as yours perhaps was was.
Cheers
