Samsung LN40A500T1F Dead?

4480 Views 6 Replies 5 Participants Last post by  [email protected]
I have no idea whats going on with this TV, so maybe someone can help me diagnose the problem.

I've had this TV for almost 4 years and it's been fine until recently. I can turn on the TV without a problem, and it works (with picture and sound) for maybe 30 seconds to a minute. But then random colored lines/bars start to appear throughout the screen of the TV. The TV will start to make high pitch whiny noises and turn itself on and off. The lines/bars and the whiny noise continue throughout this restarting process. I have to unplug the power cord every time for it to stop. Has anyone else had these problems before or know whats going on? I am obviously out of warranty and having a technician come in to look at it will be $65 by itself. It probably wouldn't be worth it having someone come in.

Any help will be appreciated! Thanks!

Google "Samsung capacitor problem." If that's what it is, Samsung may fix it for free.
It's possible that's what's causing it. I've seen some really weird issues resulting from bad caps on the SMPS.

Call Samsung and see if they can set you up with a Samsung certified technician to come out and work on it for you. It might very well be covered, as mentioned by the above responder.
Thanks, guys! I have already scheduled a tech thru Samsung to come look at it. Will let you guys know if it ends up solving the problem.
I have been used this TV for about 2 years and 6 months, I have same problems, which are automatically turn it on and off, and noise screen, and now i have air bubbles on the right bottom of screen. I called service and technician took a look this TV, he said he can not fix it, because Samsung don't make the parts for this model any more, It is really sucks. I have another TV from Panasonic, It has been used for 12years, still working well. What should I do?
Bubbles on the screen is probably the panel. That's the part that he probably can't get anymore. You could try finding it, but since there's so many other problems with the TV I would just junk it. Especially since the price of a panel replacement will run you more than a new and better TV.
if you decide you are going to junk your tv's i could use a main board from one of you. get back to me if you are willing to part with one.
