Our coach is just a year old but our main tv is making us CRAZY! It worked for awhile, several months, then would just turn itself off. Then later it would just make a three note tune, every 20 seconds or close to it, until we unplugged it. Wait a day, plug it in. Nope just the ping, ping, ping. Took it to the dealer, and of course, they plugged it in and it worked just fine, yayyyy!
We are home, and back to the ping, ping, ping! We have pulled the plug from the wall and put it in a different socket entirely. Worked for almost ten minutes that time.
Has anyone had this problem? Our tv has a rather large metal plate mount, as it is on a hinge and swings out. I'm afraid it has fried itself.

!!

Called Samsung, but hadn't removed the tv from the mount to get the exact model #, so they wouldn't even talk to me! I was not impressed.

low voltage? try plugging the MH into a different source (home, different campsite, different campground) and see if that makes a change.

Google your model tv and see what comes up.

Don't drive yourself crazy with this. Nowadays, TVs are basically non-repairable throwaways. LED TVs are pretty cheap. There should be some good Father Day sales going on now. Buy the cheapest unknown brand that fits your needs. Try to find one that has the speakers on front.

You should, however, FIRST check your present TV on another electrical source. Take it inside your home & plug it in. If it works okay there, then it's a RV related problem, not a TV problem.

my inlaws bought a new samsung for their stick and brick house. worked a week and then started doing what you are talking about except i dont remember them telling me it pinged but it might have. I told them to take it back. They had a tech come out under warranty. He replaced the motherboard. That lasted a week. When it went back out they took it back to the store they purchased it and got another one. Sounds like a power supply problem. Televisions work on off of a switchable power supply and to be honest those are not fun to work on or troubleshoot. You can try it in a different power environment. While you are doing that try looking at ads online you are probably going to need a new tv

Had the same thing happen with my 2009 Samsung 40" in June of 2013. TV would shutdown in the middle of watching it. Could get it back on sometimes, but not always. One day I turned on the TV and got sound but no picture. Discovered by looking closely that the picture was there, but the backlight was out. So I googled the symptoms and found this You Tube video:

After watching that, I disassembled my TV, found the transformer that was bad, ordered a new one on eBay for $8.90 including shipping. Installed the new transformer, powered it up, and it has been working flawlessly every day for the last two years.
If you are handy with a screwdriver, a volt ohmmeter, and a soldering gun, then you can probably do this yourself and save a couple of hundred dollars.

But if the TV is still under manufacturer's warranty or extended warranty, let them deal with it. They'll probably just replace the board that the backlight transformers are mounted on.

Samsungs have a problem with their power supplies and are easily fixable. Google your model number with the problem and see what they say. Power supply repair kits can be found on eBay for 10 bucks. Watch a uTube on how to do the repair. No need to throw away the TV

Thanks y'all! I called Winnebago and was assured that while I had had the tv worked on at the dealer before the warranty lapsed, it isn't covered and I should probably just buy a new one. It should arrive tomorrow! Again, thanks!!
