Re: LG L196WTQ no power
Resolderd the crystal and reflowed every ic and zd on logic board. Still nothing.
Hate this multilayer pcbs, can't really find my way from pin 109 to jumper 9 :/
At D713 / 712 and so on there is some fast 3 pin switching diods: http://pdf1.alldatasheet.com/datashe...BD301LT1G.html
Gonna test them in circut with multimeter later.Comment

Re: LG L196WTQ no power
Just to let people with the same problems know:
(I've read about similar problems on a polish site where the memory ic were corrupt, but that's to much hassle - so I caved in and just bought a used video controller card on ebay for a total of 13 dollars.
Works like a charm now!
And once again - thx everybody for all the help!Comment

This was a no power initially. Thanks to your help, I discovered it was the first mosfet, so I replaced. Now, the device will power up only if the battery is NOT connected. As soon as I connect the battery, it shuts off. If I connected the battery while the device is off, it simply will not respond to the power button. I replaced the battery, and while I suppose the new battery could be faulty, I'm assuming it is not. I'm having the same behavior with the new battery. I measure .2v at the charging coil. Manually applying power to the + and - at the battery header, there is no charging happening....

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hello,
With the power button connected it either boot loops with the apple logo or no display but the charging meter shows it looping on charging every few seconds.
No corrosion any where!
Tried a replacement power button off ebay and the same.
Very occasionally it will work with the power button connected!
Same results with or without the battery.
Can it be a fault with the Audio board or the mainboard?
The touch Id assembly connects through the Audio board first then to the Mainboard.
