But did you head to samsungparts.com to see if there was a service manual?
Your post appears to read as if you are trying to repair this without the manual.
i have a 42" plasma tv sat here. the original fault was that there were red lines and dots on the screen. so i opened the back and saw that 16 caps needed replacing. so i obviously replaced all of the caps. i then tested the thing and it just came up with a blank screen. i turned off and on again and saw that the blue light flashed 5 times and then turned off. when i read up on this it said to change caps?? looked at the y main board and a few of the green 2A fuses needed replacing. so i did and i still get the 5 blinks and no picture. please help, thankyou
