In lcd install process i connected p6 and p7 for 1 minute or more and after that my delta dosen't detect anything.

I am not following the update with LCD PCB... can you explain what is p6 and p7 (test points? connector's points? pots? jumper? LCD pins? IC pins?), give a schematic of LCD board and all connections LCD board with the analog main board? then I maybe able to give you a prognosis in your trouble...

Hi kt315

It's my honor to talk you
I use a rlc meter and winded my delta coile with 475 mh
I tried a several coil and it had a good resolt
My delta detected a 90% gold coin (16mm diameter) from 25 cm in air befor my fault.
In lcd install process i connected p6 and p7 for 1 minute or more and after that my delta dosen't detect anything.
At last i changed t9 and d8 and it come back again but it sense is now weak and it dosent detect gold only too.

Please help me to fix my dear delta !!!
