42" LCD Vizio problem
I've had a Vizio 42" LCD for about 2 years. It was manufactured in '09. Several months ago i noticed a buzzing sound. Then a few weeks after that, it shut down. I can turn the tv on but it buzzez in the top left corner and when I remove the shell I notice the backlight is flickering. After about 30 seconds it shuts off completely. If I wait about 2 minutes, I can turn it back on. Same thing happens. Just a blue screen, buzzing, and then shuts off again. I apologize for my ignorance when it comes to electronics as I have no idea! However, I am pretty handy and I feel with a little guidance I can resolve this myself. I may be WAY off the mark though. I have taken a few photos on my phone of the general area where I think the buzzing sound is generated from. If this will help in anyway, I will gladly post them. Thanks for your help.

Hi all:
I have a Vizio E60-E3 I am trying to troubleshoot a no power problem with. Thanks to the help on this board and elsewhere, I was pretty sure I had narrowed it to a power board problem. The board in question is a 09-60CAP0D0-00. Image attached for reference, but not of my board (tv is put away at the moment). FWIW, no obvious looking issues with the board.
I measured voltage at power in and on the fuse and saw 120V, so power is getting to the board.
On the pins out to the main board, I got no voltage at all on any of the pins. I assumed this... -
i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double... -
I have a M60-C3 where the left edge has started showing issues as seen in the picture attached. Along with this, I also noticed some darkening on the left half of the screen which went away after I left the TV unplugged. i initially thought it was the led backlight that was wearing out but looks like something to do w the TCONN board. I searched this forum but couldn't find anyone else seeing this issue. most of them were LH/RH completely gone. any insights or guidance is appreciated.
Here's a video of both the issues: https://youtu.be/hMqc760nB3o -

Hi. I have a problem that has been going on for some time (2-3 years). It's hard to explain what it really is. Sometimes, my computer stops playing music, stops videos (starts buffering on youtube), there is no sound in games and when I minimize the game window and return to the game there is a black screen with window borders... -
Good morning,
I have a problem with Lenovo T580, which after error code 0288 suggests a problem with the display. I checked the display and it works on another laptop. I replaced the display cable with a new one. I programmed another BIOS (downloaded from this forum) and I still have the problem of a dead display - there is an image via HDMI, and the system does not detect the built-in LCD at all. The problem appears to be hardware. What can I check to confirm or disprove this? I found many threads on the Internet related to this problem 0288, but without specific solutions. Please advise....
