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.

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 don't know how to fix your issue but I have the same tv with a cracked glass front. I would be interested in buying your tv for parts to replace my glass front if you are unable to fix yours. Please let me know. Thanks, Dan

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.

Sounds like a loose video connection. Try re-attaching your cables. Also, see if the same thing is happening with DVD's
