Re: ln52b630 main board
Just to add to my problem. If I unplug the mainboard from the power supply the back lights still come on. With the mainboard connected, I will see the power indicator light on the front panel but when I hit the power button on the remote it turns off and stays off. Also, I can't seem to turn the TV on using the touch power button on the front panel and if I leave the TV connected for a long time without powering up, the power indicator light will remain on regardless if I hit the power button on the remote. also, here's the link to the original post agai...

ln52b630 main board
I tried replacing the main board on my TV and when I got the new board my TV did not want to turn on. Although it took me some time to get a new board, I was only able to find a compatible board but when I switched the board my TV didn't want to turn on. I tried putting the old board back and it did the same. Originally, it would at least try to turn on a number of time until it finally would but now all I get is nothing. The front panel LED turns off when I hit the power button on the remote but I don't hear the turn on sound anymore. I had posted a thread previously about my issue and this is... -
Re: Samsung LN52B630 LCD TV keeps reseting
So it seems that my issue is not resolved. I replaced the t-con board and it turned on initially but it's back to the usual. It turned off by itself and tries to turn on multiple times until it finally does. does this mean that it the main board?Leave a comment:

Yes, when I unplug the T-con board the chime sound is normal. when I plug in the board the chime sound tries to go but stops and it keeps trying until I unplug the power cord.Leave a comment:

Re: Samsung LN52B630 LCD TV keeps reseting
Thanks to Tom66 I've isolated the problem to the timing control board. I'm going to google the part number and purchase the part. Does anybody know of a good website? Thank you to everyone, this forum is really helpful. My next project is to figure out why my 65HM167 rear projection TV keeps burning up the lamps. I've replaced it at least 5 times. Can I keep using this thread or should I post a new one?

It does turn on and sometimes for a very long time. I checked out the video and my TV does the same thing. I'm going to try what was suggested on the video and will post my results. thanks.Leave a comment:

Re: Samsung LN52B630 LCD TV keeps reseting
I did unplug the harness cable and the backlights came on... How certain are you that it's a mainboard issue?Leave a comment:

Re: Samsung LN52B630 LCD TV keeps reseting
johnboy1313,
I have yet to open up my TV but according to general public regarding this issue with Samsung LCD TV's, everyone keeps pointing to a capacitor issue. There was even a class action lawsuit for this issue. I was hoping someone already had posted this issue and had the instruction on how to repair it. I will try to open up my TV to see if I see bulging caps but basically my TV will randomly turn off and on. It began doing this 2-3 months ago and then all of the sudden worked fine for a month before it went back to doing...Leave a comment:

Samsung LN52B630 LCD TV keeps reseting
Hi,
I tried looking at some of the threads in this forum and I could not find one that matched my problem. I have done some research online on my problem and it seem that quite a few people have this same issue. My TV turns off and on. I know I have a capacitor issue because I contacted Samsung and was told that my TV was not manufactured in the time period that would qualify it for repair at no charge. So I was looking for someone that could show me the steps needed to replace them. I don't think it that difficult to do and out of warranty repairs are crazy. Any help would be apprecia... -
