I hope someone can help.
The screen on my tv suddenly turned blue.The sound is fine and I can still see somewhat of a picture but like I said,it's all blue.The OSD looks fine however,so I would assume that the problem is in the input video processing.The problem is evident for all inputs and tuners.The power will shut down after a few minutes as well.
Thanks in advance!

The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.
Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.
Once you think you have it lined up nicely hit "exit" on your remote and option 1....
Your tv is crt-based and is out of convergence. In other words,
the settings for keeping the Red, Green and Blue images aligned have
drifted and must be reset. This is common with CRT projectors and
CRT rear projection tvs.
Refer to your owners manual for instructions on re-aligning it.
