Re: Hp pavilion gaming 17-cd with la-h471p motherboard
I measure with ground and ad_id pin on the charging port 2.097v and on the kbc 1.046v and I think that's normal. The consumption without the battery when it powers on with black screen is 1.5 amp and after a while it goes to 3 amps.if i remove the ad_id pin from the charging port the laptop power on with display but its very slow.. also even with the battery only plugged in power on but again with no display. Please help I never see something like that..
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Sony kdl 40ex720 firmware update
What do you mean a native tcon? I bought a used batv board from 46ex720 tv not for the 40 inches one that I have.

No sorry maybe I didn't explain well.. I replace the batv board not the tcon board
