Hitachi 55HDT52 Will Not Power On AT ALL!!!

Hello! I have a Hitachi 55HDT52 plasma television and it up and stopped working on me today. The television is roughly 2 1/2 to 3 years old. I have had no problems with it until today. There were no advance warning signs at all leading up to this. I just watched a blu-ray on it last night and the picture and performance was flawless. This afternoon the tv was on and without warning it tuned itself off. Even the standby light is not responding. It basically is acting like it is not plugged in at all. I tried swapping out the power cable and tried another outlet on the off chance that might fix it. Everything else plugged into the surge protector appears to be working fine. I have come to the conclusion that I may be forced to track down an authorized Hitachi repair center and pay what I imagine will be a pricy repair bill. I was hoping that maybe someone has heard of this issue before and might have a suggestion. Thanks. Hi Bradley_64 I have the very same problem the only difference is I didn't use the blu-ray. I watched tv last night into the early morning, I fell asleep, the tv went off and this morning I can't turn the power on except thru the reset button thered light wil come on,then green blinking light then off again...PLEASE,PLEASE, PLEASE HELP ME...I don't have very much money, just went thru a very bad divorce. thanks in advance heavenlyscents58

    I have the same issue with the same TV with only one twist....the TV will power but only black screen with audio. The TV (55HDT52) started blacking out at about 2 1.2 yrs old. Would unplug and plug back in and the TV would work again. Several months later the TV screen went black and now only audio works.

    Any techs out there know what I need to check to see what went out. Power board?, YSUS board?,

    Any help would be appreciated. The boards seem to run 250-450 dollars. :-(

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

No picture no sound , 55HDT52 TV . we where watching it and it just went out ?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Black sreen volume works


There are alot of checks you would have to do on this set. If you are DIY i can give some examples of voltage checks, also you can check

Take a moment to carefully observe the Buffer "Snot" Chips

(Left Side black chips mounted on the SDR Upper and Lower PWBs).

Look very closely for burns and/or small holes in these chips.

If any defect is seen, the PWB is defective.
Replace this PWB and the Y-SUS

Green LED Blinks, no picture or sound


High dc voltage shut down, theres a problem either in the power supply or a circuit external from it. The protection mode is on preventing further electrical damage.

Have it repaired or use the warranty if available..

No power to my Hitachi 42hdm12


Hi, If even trying the TV in another known good outlet, it still doesn't work, do a hard/full reset - turned off via master power or unplug for a couple of hours. If all else fails, maybe you should seek the services of a qualified professional since this involves opening the unit, circuitry diagnosing and board/component repair/replacement. Hope this be of some help/idea.Post back how things are or should you need further information. Good luck and kind regards.
