Mitsubishiwd65733tv, sound, no picture. When you turn it on it clicks or scratches a couple of times, then it will red light the tv. Changed the lamp, with another generic lamp I had, same problem.

It could be the a problem with the lamp ballist circuit, or just a bad lamp socket, or simply a bad lamp. The only way to tell is to call out a servicer as that would be alot less expensive then to get a new lamp and then that not be the problem. These problems can be a little hair pulling at times, thats why i have no hair left!! LOL Good Luck

you have mention that after 10-15 seconds T.V starts up, will you give total description of the T.V within that 10-15 seconds?

fixityrsel is wrong.
1 The "Airflow message"is just a bad connection and very easily solved.Mitsubishi has a service bulletin out and will cover the repair for free. Your set may not even have the defective connectors.
Your set was manufactured in 2004..Call any authorized Mitsubishi
servicer.

Capacitors are very easy to find! Any (105 degree) PC mount 3300uf@ 16VDC will work fine..and not bulge again..Higher Working voltage than the stock 10 VDC is what caused the problem with the caps.
Mouser electronic is one of hundreds of suppliers for those caps
Order online if you know for sure they are bad in your set.

I have the same tv and the same problem happened to me (Actualy twice). It turned out to be the color wheel motor. thats what the clicking noise is.
