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.

You can desolder it and look at its value....

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 ...

Budm, I referred to the following document that gives the circuit diagram. Check it on page number 11....

Budm, what is the wattage of this resistor? 1W or 2W?...

Re: Sharp Aquos LC-60LE600U no power period
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?

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?
Sharp RUNTKB057WJQZ (DPS-168JP A)??? [COLOR="Blue"]yes its DPS-168JP A[/COLOR]...

Re: Sharp Aquos LC-60LE600U no power period
Just checked even the variastor is blown but its number is visible so I can get a replacement for it....

Re: Sharp Aquos LC-60LE600U no power period
Hi All, I have a LC-60LE600U with blown fuse. I did quick check and looks like its rectifier is fried. Hence I am looking for actual part numbers for the Bridge rectifier, the Q7801 and R7816. Does anyone have schematics?
Thanks in advance for your help!!
