Just picked up a Sharp LC-40E67U.. I can get sound on all inputs tested but no pic.. The backlights come on and the screen is glowing bluish black. I would like to try to upgrade the firmware before I dig into this. But not sure how to do it since I cant get a pic to go into the menu... I have the firmware on a usb unziped to the root of the USb. Someone willing to tell me how to do this without being able to do it from the menu??

Re: Sharp LC-40E67U Sound NO PIC
DONT DELETE .. Got one more question.. I popped the back of and went right to the Tcon.. The TCON has 2 ribbon cables. If I undo the left one, I can get half screen to come up .But if both are connected the screen just glows dark blue/black and I have sound. I cleaned all the contacts and it didnt help. Do you all think its the TCON.. I have not worked on any TVs for awhile and my MM is still packed away in storage from a move.. If you all think its a tcon I will just order one since I can test any of the fuses or anything requiring a MM. -
Re: Sharp LC-40E67U Sound NO PIC
If you can get half of the screen to come on with normal picture which just one for the cable connected between the T-CON and the LCD panel, then you do have problem in the LCD panel which is not much you can do to fix the panel.Never stop learning

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. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. 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... -
Hello,
I am looking / wondering if anyone knows where a good firmware download link is for a LC-60LE640U, the sharp support sight says the screen is archived but offers no links.
I see backlite is active,
but I cannot get the screen to return back to menus , etc
This is all after replacing the mainboard...
any assistance is greatly appreciated. -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -

Hi.
Please if someone help me with a functional firmware dump for this KD186 QKITPD186WJN3 (WE015169S) motherboard from TV SHARP LC-26P50E.
I think this motherboard it is found in several models.
What I need is firmware for the NOR chip SST39VF1682 (IC2003) and for the two EEPROMs 24C64 (IC2002) and 24C32 (IC4501).
I am especially interested in the NOR firmware because I think it has problems.
The TV initially came only with the red STB LED on and it did not respond to any commands.
I checked the power supply...07-11-2022, 10:07 AM
