Question about Hitachi 50HDX60 50 in. Plasma Television
I have sound but no picture. was working fine for 7 mths. picture was great, and one day after watching, i turned to standby, and the same day but later on, i went to turn on, it clicked to power up, a small but very quick flash, and then nothing, just blank. i tried to re generate power supply by turning everything off at the wall and taking the plug out and wait about 3 mins, then turned back on. all the same. nothing. the standby when turning on and off, seems to be delayed also. especially when turning to standby from green to red. i press the button, the tv turns from green to red, but no click sound of which normally happens. the click sounds happens about 1 min after turned to red. weird. my swivel ( power) to move the tv by remote also does not work either now.

Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.

SOURCE: ESA 42" plasma tv not turning on
you have a bad power supply, is shorted so you need to replace it , do not turn it on or you will burn some other items and then the cost to fix it will increase drastically.

Sadly to the end I can now explain the "problem" of my question by myself ...
Because I'm was not sure if I can handle the "problem" by myself I gave the Screen to a technican at our City with all the Information I found until this point (By the way my suspicion was the defect of something at the power supply unit). Two days later he gave me a call with the information about the error: An error at the power supply unit - spare parts => 50€, Work => 200€).
Unhappily im not yet got at soldering on screens, but for 250€ i would have made a good course for this (and if I can establish i will learn it).
So now again a bit more objectively:
Error / Problem:
TV - Step 1: Power Off
TV - Step 2: Stand-By
TV - Step 3: Power-On
TV - Step 4: Short flashing picture
TV - Step 5: Reverse to Step 1
1. Find the defect Fuse/Safe/...
2. Buy the Spare part at eshop2.euras.com
3. Change the parts -> et voilá
Hopefully I could have been a little help for someone.
With kind regards,

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.
