Darkness or dinsity ?

Dear,
you don't need to find out manual for jumper setting any where if you see the mother board very closely near which Jumper want to setup you can see the printed jumper setting on mother board only,

Thanks with Regad,

Flip the TV over! Just kidding!! When you installed the main board was it identical to the old main board? If so, you might want to look at the old board and ensure there are no jumpers that needed to be set on the new board. Some companies make generic control boards for tvs but have different jumper settings for different models. The jumpers are just little black blocks that connect different pins to each other on top of the circuit board.

When a jumper is placed over two or more jumper pins, an electrical connection is made between them, and the equipment is thus instructed to activate certain settings accordingly. For example, with older PC systems, CPU speed and voltage settings were often made by setting jumpers.

Hi,what type of jumpers do you mean? if you want to clear your bios you can use jumpers calls "CLR-MOS" or "CL-ms" or "cms_clr" that it means CLEAR CMOS or CLEAR MOS (stands for mosfet transistors built in mother board eeprom" you can clear it this way:
shutdown the pc or laptop find the jumper pull the backup battery up use a screw driver or an iron pin to short the jumpers together(if you dont find the jumpers after pulling up the battery short the battery+- together) wait 10 sec and then pull in the battery after that you have to go to your bios setting and set some data if you dont you may see errors like this in your screen before windows start up:
"DMI POOL DATA CHANGED" PRESS F1 TO continue" or something like that;
and if you dont know the bios setting ask from experts to do it for you because this setting is too dangerous and may harm your hardware,if you dont know dont touch it,
and one more thing:
if you mean another jumpers?dont touch it because some mother boards use jumpers for their settings or you may harm your hardware
kind regards

open *********** board battery some time or " mother board battery
inside 3pin jumper switch. open this jumper middle pin to other pin connect some time 1 minute & jumper set previous position.
or" see mother board battery
inside reset switch

*********** board sounds like the same as a Fujitsu board.
D1115
the user manual can be found at diplodocs
It shows the jumper settings and board layout for a Fujitsu motherboard.
I hope this helps. Have a great day

tried a diff monitor-if same issue replace mb

6100 disply not working

could be a jumper that needs to be removed on the DMD board, or a setting in the factory mode, mute-182-power will get you in there

what is the board model post it then will try for solution
