Hitachi plasma tv model cmp4201u will not turn on: power light is red in standby, goes green when sub power pressed, screen may flash for an instant, then power indicator alternates red & orange. Any suggestions?

First, try the unplug it, wait a few minutes, plug it in trick, several times. If that doesn't work try pressing the power button and slap the back left side of the set several times. Sometimes, this will shock the ballast and/or lamp into working.

Try checking the wires as well if its pinch or not and try to take out all cables from other devices from the back

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

Solution:
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,

The unit senses a fault in the power circuit. It is either in the power supply unit (PSU) peripherals or in the PSU itself.

• One of the peripherals might be loading down the PSU causing it to shutdown.

1. Check the power input terminals of the peripherals for any short circuit using an ohmmeter.
   
2. Replace any part found to be causing the issue.

• The power supply unit cannot run under load and shuts down. It is usually caused by bad capacitors.
  

1. Check the PSU board for any bad capacitor.
2. Replace bad capacitors with the same specifications.
3. Make sure to replace the capacitors in correct polarity.
4. Bad capacitors look like these:
