Top 20 Hitachi 55HDX99 55 in. Plasma HDTV Questions & Answers


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

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.

Hi pardeep76.

I had a similar problem with my 42 in Philips LCD HDTV. I may have the solution to your problem.


Here was MY problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you to consider.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. 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. I would definitely shop around though.


3. 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.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It will, at the very least, give you a general idea of the process. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem.


Hope this helps.

If you have any questions for me, please comment on this page. I will be happy to assist you to the best of my ability. Thanks for using Fixya.

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.

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.

If it works, put it on Facebook MarketPlace, free to collector.

If it doesn't, you might be able to split it in the middle.

Use code search on your Sudden Link URC to find something that woks. If a search through all codes stored in the URC fails, try a different one.

I am guessing it's an old(ish) TV. As a plasma the chances are that it is on it's way out.

Please Try new cables (HDMI etc)

First make sure that the current Source or Input is set to TV. This is usually the only reason for the error message you see. To select the source, look for a Source or Input button on the original remote. If you have an universal remote with a button with the Source/Input label, you may need to try alternative codes to make the button work. (Power and channel controls will often match across multiple codes for the TV manufacturer.) Alternatively, check if there is a Source/Input button on the TV or a section of the menu system with the function. Once you set this source, try again.

Note: there was a period when manufacturers sold some TVs without tuners. They were labeled HD-ready sets. These can't do a channel scan and do not have an RF antenna jack on the set.

I hope this helps. Please add a comment with the model number of your Hitachi TV for more information on setting the source on your set.

Under Audio or Audio Settings on the on-screen menu, TV Speakers is set to On. All of the cables physically connected to the TV and the input devices are secure. Switch to a different input device and verify there is sound from the TV speakers (for example, a DVD player or a gaming console).

Without a remote control, you can't unlock it. If you wish to buy its original remote control, contact the authorized service centre, or authorized dealer to your device brand. They can either give you a genuine remote control to your device, or can direct you, from where can you purchase a suitable one.
To select a proper universal remote control, you should know about the number of digits to its set-up codes. There are 3 digit, 4 digit, 5 digit, 2 digit and even single digit codes, to some brand devices. After confirming this, check the sites linked here. Both the sites have set-up code list and set-up procedure to many popular brand remote controls. Check which brand remote control has set-up code/s to your device brand, and buy that one according to availability? Brand name of the remote control isn't a matter, but it should have set-up codes in its code list, to the device brand you have.
Please note: Every new universal remote control will have set-up code list, and set-up procedure along with its pack. Never accept a remote control, that hasn't both of this. For more details about the set-up codes, visit the site http://electrohelponline.blogspot.com/ Check this site too. http://remotesearch.blogspot.com/ Universal remote controls are available at most of the electronic spare part selling shops; and by Online shopping.
