Depends on how old it is and what the model number is. Do you think all TV's are the same man? No they are not.

It is likely the projection lamp is weak, causing the picture to cycle on and off. Take the lamp out and examine the reflector. If it is dull and cloudy, it's time to replace the lamp. A new lamp will have a reflector that is shiny and looks like a mirror. Be sure to rate this solution. Thanks!

SOURCE: Hitachi projection TV does not power up

You probably have a blown 2kV capacitor and 2 amp fuse. Look for signs of black burning inside.

SOURCE: Have a Hitachi 53sdx89BA Rear Projection TV. Turn

Discharged Flyback Transformer. Removed main pc board from bottom of TV and flipped over, no apparent damaged components or blown board traces were found. Noticed a lot of flux in various areas on the board that seemed unusual (maybe TV was worked on before as I bought a showroom demo at Circuit City). Used a plastic screwdriver to remove all flux between connections on ICs, Transformers, Flyback Transformer, and various other components. Cleaned all debris, dust and crud accumulation (TV is over 10 years old and there was alot around the Flyback Transformer) from both sides of board using a lightweight paint brush.
Used a magnifying glass to check all solder joints for possible cold solders and found none. Did the same for Power Supply Board. Checked various ICs and Power Transistors for opens or shorts (in machine) and they seemed fine. Reinstalled boards, said a few Hail Mary's and fired it up.

The protector Led no longer flashed under power and lo and behold I got picture and sound!

I cleaned the lens on the projectors (again 10 years of dust accumulation) did a magic focus adjustment and it works fine!

After reading other fixes, I fully expected it to die after 10 minutes so I left it on all day and against all odds it still works.

What was the fix......Dirt buildup on and around Flyback and other components,,,,,,Flux conducting electricity between contacts on Flyback and other components.....or oxidation on connectors between Power Supply and Main Board.....I don't know.... all I know is that for the moment I saved around $ 300 - 400 in repair bills by doing it myself.
