Hello,
i have many 5050sff. all of them, and how i experienced over many years for all about 250 DELLs goin through my hands, are fully flashable and can be serviced in any way when the service_mode jumper is set.
Never ever i experienced problems with that.
Now i have one 5050sff machine, where this jumper isnt working at all.
I do not get the normal messge that the jumper is set when booting and a short test with FPT just confirms this. Everything is locked -->> EVEN for reading !?
The history of the machine is that i used it in my office... -
Hello,
Apologies, I broke a rule and hijacked a thread, so I deleted that post.
I am curious if anyone here owns the G8 or has good quality board shots?
I've done some googling and curious if the 805 G8 series has some kind of jumper?!
The 800, G3 series, much older, the maintenance and service guide, clearly talks about a PSWD jumper

This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board.

The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp... -
Hello, I'm new to this forum. I like to tinker with Sony electronics, I have been lucky trouble shooting sony stuff, But I can't find much info on this Sharp TV.
