    I have the 50v500 the power, heat and lamp lights blink at the same time upon start for about a minute then the engine shuts down afterwards the only light remaining on is the lamp light. There is no sound or picture just the motor or fan noise when I turn on the tv .. Tech said it could be the ballast or the temp gauge after a brief examination of the lamp. No major diagnostics have been performed.

    Hi. I have the same problem as this. TV powers on, both fans come on briefly, and the bulb comes on also. Screen flickers for a moment, then everything powers off. Once off, the TEMP light blinks. I have replaced both fans, and also replaced the Power P.W.B. board. What should I look at now?

    Thanks for any help!!

    HHMMM...I would like to update my problem, I hope that by doing so it will be easier for one of you experts to help with this problem.

    When I turn it on, all of the LED's turn on, but in a few seconds when the TV powers itself off...the green LED at D913 stays on. All of the others turn off. It will stay on until you unplug the power from the TV.

    Thanks for any help!!

Hello Ecollier2012,

I have a Hitachi 60v500a with that has that same type of problem (comes on briefly then shuts off), and the green LEDs on circuit board light up for a few, then turn off (except D913, which stays on), would one of those repair kits work for this unit?
Which board is the blown cap & pico fuse on?

Thanks!!

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

Ok well i have a Hitachi 50v500a i have had the light engine replaced about a year ago with no issues, but now when i power up the tv it starts fine but when the picture comes on there are blurry...


Sir try to check if there is a loosed connection in the light engine or cold solder in the electronic circuit board, this loosed connection cause your unit to malfunction, or the light engine of your unit is getting faulty. Good day sir and best regards.

Hello
The power regulator board in your Hitachi is not switching. It is an SMPS [Switched Mode Power Supply]. Normally for plasma TVs the power supply repair will be almost impossibele due to lack of component availability. If the fuse is OK, definitley the switching process has failed it it. There is an IC which oscillates at high frequency, whic its oscillation signals are given to MOSFET transistors to chop the incoming AC, converted DC voltage. These switched voltage is passed through SMPS transofrmers which it turn generates secondary voltages that goes to different circuit boards of your TV. The power board is the most important section in a Plasma TV. it must be perfect in every respect in terms of secondary voltages. If any one of this voltage goes over than specified, the main boar will get damaged. So it is adviced to replace it as card basis, rather than making "sugery" to it. The power supply board can be had from Authorised Hitachi Service centers. You just give the the exact model number of your Hitachi TV. They will give you the orginal power supply board. Never play experiments with Plasma TV. OK.

I have an older Hitachi 36'' Ultrvision TV. It has worked fine for years up until resently. The problem that I am having is I can not get the direct TV signal to come in. The out from the Direct TV box...


Sounds like you have something in the wrong setting that won't allow the signal to get through. If the video 1 line works OK but regular input will not work, that is almost certainly the problem. I would try just unplugging it (turning it off is not the same thing), let it reset for a few minutes; then plug it back up and see if it will reset by itself. hope this helps.

Hitachi 50v500 goes black and then comes back on.


Sounds like the light engine. They are having major problems with it, but Hitachi is replacing the part for free, with you paying for the installation. Need to call Hitachi customer relations.
