Re: A guide to fixing/troubleshooting some common plasma TV problems
It should be locked or pruned significantly. If I were something looking at the title of this thread, I would expect one or two posts at most from the author. Not a hodge podge of questions on various TVs.
However, I know the feeling. Even when I explicitly say don't ask questions in post #1 of a "how to guide", people can't or won't follow instructions.--- begin sig file ---
If you are new to this forum, we can help a lot more if you please post clear focused pictures (max resolution 2000x2000 and 2MB) of your boards using the manage attachments button so they are hosted here. Information and picture clarity compositions should look like this post.
We respectfully ask that you make some time and effort to read some of the guides available for basic troubleshooting. After you have read through them, then ask clarification questions or report your findings.
Please do not post inline and offsite as they slow down the loading of pages.

Re: A guide to fixing/troubleshooting some common plasma TV problems
Hello, I have a Hitachi 42 inch plasmas, model number: HD42S69. I have a 3 inch thick vertical red line, left of center (if your facing the tv) that sporadically appears, but often. I took it to a repair shop. The guy told me that its not the control board and it isn't the display panel, it's a buffer board. He wanted $200 and he said the part is like $60. I figured I can just do it myself, but I don't know where the buffer board he was talking about is? Can you help me locate it? How do I even know what board is causing the issue?Comment

Re: A guide to fixing/troubleshooting some common plasma TV problems
It's more likely just the connection between the X-buffer board and panel. Start a new thread and provide pictures of inside your set, and you can probably fix it yourself.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: A guide to fixing/troubleshooting some common plasma TV problems
Looking at the picture, it also looks like the Y-buffer may be bad, but the X-main is causing the discolouring too.Last edited by tom66; 07-18-2013, 01:17 PM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: A guide to fixing/troubleshooting some common plasma TV problems
Tom congrats on your wonderful guide!
I have an LG 42PC1DA and when I turn on the the in the morning (when the tv is cold), the image is distorted and pinkish purple, then in clears up and the image is near perfect.
This is very much like the image you show on the guide for this problem :"The picture is slow to update (motion blur) and has a purple or lilac tinge to it."
I dont own voltage testing equipment. Do you think it is a good idea to just change all the fuses on the zsus board?
Please help.Comment

Re: A guide to fixing/troubleshooting some common plasma TV problems
If the problem gets better over time, it is -unlikely- to be a fuse issue.
It is best to start your own thread and add pictures to it.
A multimeter, essential for all TV repair, is available for under $10 from many good retailers.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
All left and right refers to looking from rear of TV (or looking from front with TV upside down)
- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

Hi,
I have this almost brand new Plasma was well stored. I would like to repair it for a friend of mine.
I have noticed that it works for few seconds then switches Off the Power_ On signal. Have disconnected boards and left maion board and power supply and still the same. The power supply with PS_ON and VA signals On stays on so it is not a problem in the power supply.
Any one met this problem in the past?...10-08-2025, 07:34 AM
