Hello all. Been wandering the internet amilessly the last 3-4 days untill i found this site. I have some problems with my vizios. M420SV it turns on, the screen gets lighter, then darker, then lighter again thats it. I was going to replace the main board but hard to find. My E3D470VX has a green vertical line on the far right of the screen. No idea about that read about t-cons and invertor back light boards but when i opened it i could only see the main and power. Not digging far enough or missing something? I have checked the caps none are blown from what i can tell. Any help would be appricated.

Re: New here problems with E3D470VX vert line and M420SV power but doesnt boot vizios
The T-con is usually buried under a metal shield and is mounted close to the LCD panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Some screens have a setting to adjust your backlight according to the light there is in the room the less light the darker the screen gets you may have to disable this feature.
I am not positive weather this is the problem but I have seen it a remedy was this for me.Please note: I am not responsible for any harm caused to you anything discussed is just discussion. Before you try anything discussed be sure that you have the appropriate knowledge and safety gear for the job. Like with anything education and safety are first! Do not try anything @ home without it.Comment

Hi to all,
I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.
I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.
Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...01-10-2024, 01:26 AM -
Hi all.
I have a Kogan 65' LCD Panel with a thin blue vertical line (top to bottom) on left hand side of panel.
The line just happens to coincide with the end of COF and start of the next COF (attached).
The line is permanent no matter what I've tried. I've tried pressure testing the panel (top to bottom) and all over, I didn't notice any difference with the line, either temporary or semi-permanent.
Also tried unplugging all flex cables, cleaned with isopropyl then re-inserting to no avail - line remains.
Hoping to fix... -
Howdy everyone! I hope all is well where ever you are!
I'm attempting to integrate a couple of LED pods into an automotive reverse lamp circuit. The problem being, while the vehicle is running there is a 8.5v current present on the reverse lamp power wire. Needless to say is that all LED pods and lights dimly illuminate while the 8.5v is present, so the LEDs are always powered on while the vehicle is running. When the vehicle is shifted into reverse, the voltage changes to 12 volts.
I am uncertain how to convert this line into a switched 12v output line for the LED pods.... -
hello,
there is an asus gtx1650 which displays fine in windows but if i run a benchmark test it displays artifacts and the driver crashes after a second or two.
I changed pads and thermal paste.
I run mats test but it is reporting 0 errors.
I then tried to run the mods version 400.271_1650 test, it first ran and stopped with a 'breakpoints limit reached after 5 retries' error and the fans went full speed.
After a reboot, I tried to run the test again, but now the test fails and says "ERROR: Couldn't clear GPU's interrupt...02-09-2022, 03:22 PM -
I have a 2DS that I am working on that has a problem reading SD cards. It knows that card is in the slot (which, means the detect pin is working anyway) but it says it canβt read the card.
Here is what I have done so far:
-Tried SD card in another 2DS and on PC, works great.
-Tried piggybacking another SD card slot (just so I didnβt have to take the other one off), same issue.
-Compared voltage drop readings from a working 2DS to the faulty one. All reads are very close except one, the 7th pin from the left, with the pins closest to you, which I believe...
