Question about Hitachi 55HDX99 55 in. Plasma HDTV

1 Answer

I have a Hitachi plasma Model #55HDX99 and am having issues with volume control. I cannot "lower" the volume by any means - even on #1 volume it sounds like #50!!!! What can I do to fix this????

I have tried to control the volume using the menu options and turning "off" surround sound, perfect volume, as well as loudness and cannot get the volume down to a "normal" range.

This happens to me about every two months. I unplug the TV wait 30 seconds and it comes back on. I hope that works for you - it's a much cheaper solution:-)

Check the settings on your external devices,check the settings on the devices you are having a problem with. For example, if your Blu-Ray player is outputting to 1080p but your television supports a resolution of only 720p, this could cause the audio and the video to slip out of sync.

Try different inputs. If problems persist with external devices, plug them into different ports. The problem may be a bad input rather than a bad TV. Replace cables to make sure that isn't the problem.

Check the settings menu. If the image on your Hitachi TV looks too dark or too washed out, adjust the picture settings in the television's main menu. Sometimes the factory settings on a Hitachi TV aren't in line with the needs of the user

If this does not solve the problem,Press Menu Button, then in sequence 4, 7, 2 and 5.You are now in the Service Menu

Goto Options and press Factory Reset, it will only take a couple of seconds

Press Escape, Standby and Unplug from Mains Leave for 5 mins and turn all on again

If the problem persists, Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. They can be found online.

Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

NOTE; If your tv is still under warranty,do not open the tv as this may void warranty.Best option will be to send the tv back to the dealer for replacement.

Is my problem the Main Digital Board?

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

55HDX99 picture is getting darker and darker. Have adjusted settings but no improvement. It's 4 years old and has probably less than 7000hrs.

I would try that if available but suspect a bad board somewhere in the set--average life on all Plasma sets is 3-5 years so maybe time to upgrade to a new set?

I have a hitachi p50t501 plasma sound wnt go up or down stuck where its at but the volume bar goes up or down but volume wont change

This means that the logic control is working on the controller unit but the audio section - audio amplifier drivers - are not responding.
So it seems that the audio preamp section is faulty and it can be confirmed only if signal test or a voltage check is done and traced.
The changes from the logic control must be traced to confirm the section.

I have a plasma 55 dirctors cut. No picture or sound was told upper y board was bad replaced it and still doing same thing

It is really hard to fix sets like this without voltage checks, but if you have any led lights flashing this may tell what is wrong with your set. Also if there are lights in the back of the set that are flashing on the logic board or the Digi-Main PWB But usually with a bad digi-main you have audio, also check the buffer board and see if any holes lie in the buffers. These are the boards on the far left side of the set looking from the back. The buffer chips are the black square IC's sometime you will see chip pieces out of the buffers. This mean that one is bad.

My plasma picture looks green

You are proberbly using RGB leads, wich is red green blue, each colour runs through each cable, have a look at your cables maybe one is loose, or damaged. check on both ends, but the cables MAY NOT be red green and blue, but the terminals that the plug into will be.

Black out?!?!?

I finally got information from the repair shop. Apparently it is the upper and lower panel drive. The parts are supposedly not more than a couple hundred dollars, though I'll let you know when I get the bill. I do want to say that Hitachi was great when I called them. Even though my plasma is out of warranty by a few months, they agreed to pay for parts if I pay for labor. That just might keep me buying Hitachi products despite the issues I've had with my 2 plasmas.
