If I replace the board with the buffer ic's I should be able to get display again then?
I haven't seen any cracks in the screen.Leave a comment:

I have a Samsung Sp-r4212 with no display but I'm getting audio.
I pulled it apart I saw a bad ic on the YB (up) board. Could this cause the problem?Leave a comment:

Re: Viore lc22vh56pb
The TV has a main board and the power supply board, are you refering to the main board as the t-con hoard or just a section of the mainboard? Since 12v is present at the power supply then u should be able to get 12v on the main board but I'm not sure where I should check since I don't have a separate t-con board.Leave a comment:

Re: Viore lc22vh56pb
I connected the 1 k resistor from Stb to Bl on and the back light came on, nothing happen when I connected the 1k resistor from Stb to on/off. I am getting 11.91v on both 12v pins and 5.21v on both 5v pins.
I removed the resistors and reconnected the connector but it's the samething, the red standby light doesn't come on it shows a green light which would indicate its on but nothing shows on the screen and back lights are off and power button has no effectLeave a comment:

Re: Viore lc22vh56pb
I don't think it's rust, I think it's the hot glue they used but it's all dirty now, I could clean the board though, I only have alcohol at the moment, some ground terminals on the power supply board are corroded thoughLeave a comment:

Re: Viore lc22vh56pb
On/off 0v
Stb 5.21
5v 0.5v
5v 0.5v
Gnd 0v
Gnd 0v
12v 0v
12v 0v
Bl on 0v
Dim 0v
Gnd 0v
Gnd 0v
If I short stand by to 5v then I get 5.21v on 5v rails also but screen doesn't come on....Leave a comment:

Re: Dell Inspiron N5030 external power idea
I have a dell n5030 that originally wouldnt charge, I replaced battery and same problem, I didnt even get a charging light I was only getting 3.3v on 2 pins, I replaced the 3 fets closets to the battery terminal and I started to get 3.3v on 3 different pins then 19.3v from 2 other pins on the terminals aswell wen i tried the battery the light may come on for a couple seconds then the laptop chips out, I assume that voltage is too high, could I get some assistance?Leave a comment:
