Re: Samsung UN65H8000AFXZA Backlight No Image

So today I got some freeze spray (compressed air) and decided to spray it around the part that I thought was good the main board and I got 3 light on the tcon board briefly and some white lines on the screen. But now I am getting power loops where the tv backlight comes on and promptly off. The highlighted part of the image is where I sprayed it.

Re: Samsung UN65H8000AFXZA Backlight No Image

Sorry didn't make that clear but I couldn't get either side of the screen to work and had 2 of 3 leds each time.

I have a Samsung UN65H8000AFXZA that I got from a friend a year ago. The Backlight comes on but no image. When I connect it to my laptop it picks it up as a 1080p 60hz monitor that I can use as a secondary so the logic board seems fine. I have checked all the voltages and they seem to make sense. I got a replacement tcon board but the problem persists. On the tcon board I am getting 2 of 3 leds lit up. I have tried unplugging 1/2 of the tcon to get half the panel working and tried taping over some pins. If anyone has a service manual or anything that can be helpful please post. Also if you want...

Tore the battery apart and the main IC on the charge board is corroded with 3 pins missing. Are ifixit batteries any good? Also Thank you very much for your input and time.

Re: Macbook Air A1466 820-00165 Won't Boot with battery installed.

I'm getting 0v across PPVBAT_G3H_CONN

Re: Macbook Air A1466 820-00165 Won't Boot with battery installed.

PPBUS_G3H on battery 0.04v
PP3V42_G3H on battery 0v
PPBUS_G3H on charger 8.58v
PP3V42_G3H on charger 3.43v
PPBUS_G3H on battery+charger 8.58v
PP3V42_G3H on battery+charger 3.43v

It also looks like the battery did not get a charge overnight. Sorry if this info is useless I have very little experience working with macs

With just the battery only it does nothing. I have no access to a new/known good battery. I will check and post the voltages after I get back form work. And thank you for your help.

Re: Macbook Air A1466 820-00165 Won't Boot with battery installed.

Just tried it, Got sound back so guess nothing is wrong with it but everything else remains the same.

I have a Macbook Air A1466 820-00165 that will not boot with the battery plugged in, it will boot of the charger but only when the battery is disconnected. With both the charger and the battery connected I get fan spin for about 5 seconds before it shuts off. When powered off the charger with the battery disconnected everything seems to work fine. It boots into the OS sees WiFi both keyboard and track pad work it also doesn't have a chime I believe but that's for later on. I have both the BoardView and schematics for this board. If I skipped any info or you need any more details please let me...
