My Samsung LN40B530P7 TV will not show anything but a black screen
I got the thing out of my neighbors trash and it seemed to work fine, so I started using it and I noticed after about an hour of use the tv would heat up and start flickering a little, the longer it let it run the worse the flickering became also I noticed if I rocked the TV back and forth it would make it flicker more or stop flickering for a few seconds, I figured it was some type of loose connection, so I took off the back cover let it run to the point where it was flickering badly, and i started wiggling connectors, I found one that I disconnected blew the dust out and reconnected it and the flickering would stop, I would wiggle the connector and it would start again. I figured that this had to be my problem. I lost trust in that connector and decided to take the board out and just solder the connection in directly to the board. But when I put it all back together, now when I try and turn it on I hear the welcome sounds and the Indicator light flashes 5 times, but there is no picture, I would greatly appreciate any help or advice that you have!
Is this a good question?
the very first thing you want to do is to post plenty of images of your boards as well as of your repair. A connector usually does not fail after it warms up etc. that is more a bad heatsink, caps or mosfet error. Let us see how you fixed it.
