Update: I found a swollen 22uF cap on the video board that I replaced. This has led to reduction in the frequency in this jitter. I noticed that 4K videos on Youtube work flawlessly for almost 6 hours, however upon playing regular videos from Youtube, the jitter appears back again. This behaviours persists unless the tv is turned off for some time and then restarted.
Please let me know if you have any ideas on this.

I am facing similar issue in my Vizio M55-F0. One photo is when its not flickering and the other one shows with flicker. Is this TCON or main (power) board issue?...

Sam, There are multiple ways to do this - depends on your interfaces and what role those computers play on the battery testers, and the software capabilities... there is a software called Nagios, using which you would write your own scripts and capture the data from each of these computers, and then collate them to represent it on a dashboard..
you may be able to take use of Copilot using which you can screen scrape the data from the computers and populate a table and then display them on screen...
these are not the only two ways as there are multiple ways of doing...Leave a comment:

Thinkvision P27h-10 Monitor Backlight
Hi All, I am looking for the specifications of LEDs used in backlight of this monitor. By measurements looks like its a 4014 LED however I wanted to know what is the forward voltage and the warmth of the LEDs used here. From Aliexpress and datasheet of the mfg I can see that they make them in 3V and 6V variations. and 3000K 4000K 5500K 6000K 9000K in warmth rating.
Any help will be appreciated.
Thanks... -
Sam, This is possible via the hardware route where you take identical monitors and pry open the LCDs and remove the backlight and filter from one of the monitors leaving only the LCD layer and then disassemble the other monitor and insert the bare LCD from first monitor into second. You will need quite a bit of skillset to be able to do that.
However when I read your original usecase, you can go software route of using HTML and javascript to show the twobattery monitors without disturbing any of the screens and doing delicate maneuvering of hardware approach. This way the look and...Leave a comment:

Re: Garmin Dashcam 20
Thank you for taking out time to read through and responding to my post!
After I posted, I was able to connect it via Garmin Express and firmware update was done. I ran the dashcam on battery so the power cable having issue is ruled out. As I mentioned in my original post, using a new SD card with same class category that Garmin prescribes - Class 10 still no avail. My next step is going to buy a new SD card with the exact same specs as mentioned below:

Garmin Dashcam 20
Hi All, I have a Garmin Dashcam 20. It allows functions to work only if SD card is inserted but it freezes upon inserting a working SD card. So far I have cleaned the SD card socket with alcohol and all of the connections looks good. I also tried using a brand new class 10 SD card as its manual requires but still its not working. Garmin Express is also not able to detect the device.
I am able to get into menus using a bad SD card.
Let me know if anyone has ideas on what to do. -

Re: Sharp Aquos LC-60LE600U no power period
Budm, heres the picture of the whole backside of the TV showing all boards connected together.
I replaced the defective bridge rectifier, blown fuse, .56 ohm resistor and the zener diode. After shorting PD 14 and 15, I can see that the pf capacitors are getting the proper voltage of 400V. Connecting all of the boards together when I connect to power, the white LED turns on, backlight turns on momentarily before turning back off. atleast 1 step forward

I was dignosing the TV further and found on the board KF905FM04 and found the diode 9601 is bad. Does anyone know whats the value of this diode?Leave a comment:

Re: Sharp Aquos LC-60LE600U no power period
Thanks for the superfast response BUDM. Do you know the value of R7816? Looks like owner replaced (or got it replaced) the resistor. Currently it has a 6.8 ohm resistor. Not sure if thats the right value.
If that PFC MOSFET is blown, more likely the components connected to the Gate and the PFC IC are likely to be damaged also.
You should attach the pictures of the board?
What is the P/N of the power supply board?
