I was having problems with my plasma displaying vertical lines only on the far 3 inches of the right side top to bottom and now today it powers on and then buzzes and powers off no picture and no sound I took the back off and found the buzzing coming from the ysus board so I unhooked it and now the tv comes on with sound but no picture. Would installing a new ysus board fix this problem?

For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

Re: Zenith Z42PJ240 YSUS Board?
When the tv had the vertical lines if you hit the back of the tv they would clear up would this be cause by a bad buffer?Comment

Re: Zenith Z42PJ240 YSUS Board?
A buzzing sound emitted by the TV is indicative of a broken panel. The fact that the buzzing stops when the Y-sus is disconnected just means that the panel is not receiving any voltage not that the Y-sus is bad. Perhaps in the process of hitting the TV to fix the vertical lines you cracked the panel near the edge or broke the glass nipple on the panel.Comment

Re: Zenith Z42PJ240 YSUS Board?
These tvs would eat y sus boards for breakfast, lunch, and dinner. (as would many other plasma tvs)
I would agree with Plainbill your original problem was the x buffer not the y sus.
It may have just been a connection issue. I have repaired a few of these and I have had the problems you are talking about.
Mostly I have replaced the y sus
When you unplug an x buffer the y drive and/or z drive buzz louder.
Chances are you just have a bad or weak connection.Comment

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... -
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 There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
