Question about Hitachi 55HDX99 55 in. Plasma HDTV

1 Answer

55HDX62 .. Plasma Owned the television for about 5 yrs without any issues. Turned on, watched for about 5minutes. >Saw slight spark from the upper right rear of the unit (it reflected off the wall behind it). >Sound remains, no longer picture. Tried the usual, on/off remove cable, etc. Did I just blow my plasma lamp? I seemed like a light bulb that blew (similar in sound and sight) I am pretty handy, and try to fix everything that is broken or upgradable including electronics (build my own home pc's), cars, motorcycles, home electric work, etc.. Do I get involved from this point and attempt to diagnose/fix problem or do I just call a tech??? ($150-200 parts/labor not a major problem.. +$400? I'll start to get resourceful/patient)

The spark you have noticed, is most likely to be a blown capacitor. Since you have sound, my money would be on the sustain board(X-sus or Y-sus or both). Unplug the set, take off the back cover and tell me what you find. Get me part number off the board so that I can confirm if whether its the sustain board.

Sounds like a capacitor has blown or something has short out.

Panasonic Viera TH-42PZ80U Plasma TV Will not power up. No blinking lights. No lights. Owned 2.5 yrs. Just tried to turn on heard a click like it turned on and back off and no longer works. Tried new...


There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

I currently have my 55HDX62 Hitachi Plasma wall mounted. I am moving the unit to another location and wish to place it on top of a TV Stand. I do not currently have the table stand which came with the unit...


Even you find it the shipping won't be cheap. They do make universal stands for LCD/PLASMA TVs. You may want to see at Walmart or a similar store if they carry the universal stand.
About a year ago a customer brought a 55" Panasonic plasma TV to our shop, and we asked him to bring the TV with the stand he found out his wife, trashed it and he made a nice stand out of pieces of wood. If you keep looking on ebay you may be able to it.

Best of luck

The screen needs replacing if cracked. It is usually cheaper to buy a new TV than get it repaired.

You most likely have image burn in on the display if it is not in a straight line. If it is in a straight line than it can be dead pixels. It is most likely the first issue I saw this same issue at work with an HP plasma TV.

First of all if the "technician" said the LCD panel possibly but this is a plasma then BOOT that tech, he/she doesn't know what they are doing. You probably have a bad logic board as I have seen with a few Hitachis. This is obvious to a TV tech because the logic boards on Hitachis have LED's on them to indicate their condition. I would get a second opinion on this repair. Avoid the person who thinks its the LCD panel when it's a plasma TV.
