I have a hitachi c50-FD5000; the power led comes on; and the screen appeares blue with a faded picture and sometimes the screen just becomes blank; please assist how can i solve the problem

SOURCE: Hitachi HD 1080 has blue power light on but no picture

Press the reset button...it's on the bottom to the right (underneath the TV). Same thing happened to me.

SOURCE: DP23 LED not lit on deflection board no picture on tv

Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.

Your repair didn't address the failure. It is much more likely (in the absence of video and sound) that the power supply has failed.
The items you replaced affect convergence and have nothing to do with the audio section or the set's ability to receive signal. The power supply failure will diasable everything.
Look for a separate board with larger-than-average components, some cylindrical (capacitors), some block-shaped (chokes and transformers). And you may be able to recognize its relationship to the AC input line.
Locate the assembly number which may be on a paper label or just printed in ink on the board; any that appear to have been part of the etched traces will be only the empty board number, not the assembly.
Removing and replacing this assembly can be done by most everyone using a little common sense and just plugging in the connectors where they belong. Call your Hitachi service center and ask about potential repair or replacement costs. If you can score a new board, don't throw away the old one since the new board will be as crappy as the original. This way, you will have time and opportunity to find an independent reapir service for these and have a spare on hand for . . . sorry, the next failure. These things aren't 'your father's TV', they die much more often.

Hi, usually an indication the lamp has failed,
replace in last 2 years??? video-tek

SOURCE: Powers up but picture doesn't appear.

Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.
