Re: Samsung 46'' LCD TV LN46A530P

The image flashes on the screen almost like it reboots and the image on screen slowly scans down and then its normal static on a TV. I could take another video of it but not sure how much help it would be.

Yeah I will get the caps I just have to go through it again and measure them and record their uf ratings. Then find a few extra bucks in between buying Christmas gifts. I know mouser always double charges me and refund my money like 2 weeks later so maybe digikey this time around.

Actually if you view my video in the...

Ok so I power the thing on today and its on the left side now. After I turn it on it takes about 8 seconds but it flashes to a normal static screen. So maybe bad contacts to the t-con? Or the t-con board?

The only caps I replaced where 2 that where budging and a 3rd one I tested on a capacitance meter and it tested a little low so I replaced it for one that read right on. That 3rd cap was a 100uf cap, I could get a cap kit and just redo all the caps in the power supply. The caps all tested good other wise when I pulled and tested each one.

Ok, so I took the metal shield off and looked at the ribbon cables no delamination that I can see. I took them out one at a time and reseated each of the 4 ribbon cables then the problem seems to have jumped to the left side of the screen. I reseated the cables a few more times and can see some slight distortion on the left side before the screen fully turns (screen is still black) on then it pops to a normal screen when it fully powers on. Either it warmed up some or that board might have some issues. I will try it again tomorrow morning and see...

Where is the tcon board located? This is the first time I have messed with newer TV's. I know plenty about the old CRT TV's. Is it the one at the top middle of the back of the screen?

Also what would you use to heat the board up as a test?

I have a Samsung 46'' LCD TV LN46A530P that I picked up from a neighbor that was sick of dealing with it. I fixed an issue it had where it turned on and off many times before it would stay on that was just a few bad caps on the power supply an easy fix. Now its on to the 2nd issue the TV has, the right side of the screen will turn a washed out white color and stay that way for a while and then eventually after the TV is on long enough it goes away.
