Question about Hitachi 50V720 Television

Open Question

Green power light, red temp, & red lamp light flash in sequence

Hi my name is Henry. I have a Hitachi 50V750. It was doing OK.
I did get the blue line that eventually took over the whole screen.
Now while watching, the TV stopped dead (audio & video).
Now when turnung the TV on, the green power light, red temp, and red lamp light flash in sequence.
What does this mean? Is it the bulb shot?
If it's just the bulb, would I still have audio or are there other problems?

Regards,
Henry

SOURCE: my power light on hitachi lcd is flashing red and

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,
NatureOneFreak

SOURCE: Hitachi 50" Plasma (P50X01AU), power light comes on but no screen

Hope you already resolve it, if not, here what I went through 1. Try to get a service manual for your model ($10-18) from http://www.service-docs2.com or similar place. 2. Open the back and follow instructions how to remove and test the SDR-D and SDR-U board on the far left (take one off, see if you could see half the picture). Inpsect the chips on those two boards, you might be able to spot the burned out holes (that would be the defected board, seemed to be a known issue for particular models) 3. If it is the board, go to ebay and get the pulled out board replacement ($70-90) I fixed my 50 inch plasma this way

SOURCE: Hitachi Plasma HDTV turns off by itself. indicating lamp flashes.

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:3a72a3c.jpg17dffa0.jpg

TV went off, and three lights come on (green "power", red "temp", and red "lamp")for just a second, in succession from left to right.


My television had two red lights flashing, one for Temp and the other for the lamp. I removed mythe lamp assembly and the bulb filament was burnt out. I order a new lamp and housing unit UX21517 and replaced it and now I have the red light flashing which is calling out the lamp again.
