This widespread problem seem to be across all of Samsung HDTVs. A lot of owners past warranty replace blown capacitors on the set powerboard. There even a YouTube video showing how to do it.

I am not 100% sure since its been a while, but I think it does not automatically turn on after power up and return to the channel. you should ask the seller.

Every time I've hooked up one of these units I've used the optical out of TV haven't had any trouble with powering on, if using separate TV and sound bar remotes try turning off Hdmi control on TV

Hi Paul,I bot mine in late Nov 2010. It has a VIzio remote with a slide out querty key board. And yes, my tv does occasionally shut off. It usually takes a minute or 2 to reset and turn itself back on. It happens about once every 3-4 weeks with my set - sometimes more frequently. From what I have been able to gather from reading reviews, not all sets have this problem. And the severity of the problem seems to vary with those who have it. Other than that, I love it.Jer

yup i have the same issue apparently its cause of the tv drawing lot of power dur to its fast start up . try plugging it in to the wall direcly ie with no other devices plugged in. i also notice that it only happenes if i have had the tv off for a while eg over nigt and not if it turn it off wait a few mins and turn it on so it must be some thing with the power. i would still call samsung and see whats up.

Yes, I love mine, turn it off when u r done running it. it decides to run around by itself. creep me out at first, I figured out the tv remote has something to do with it. lol

I have not had this problem with mine, but did find that the remote doesn't always boot the unit. It has come on fine after pushing the top button on the back - or - simply by unplugging and plugging back in. Sorry I could not be of more help.

I haven't had any problems myself. Has your TV been updated to the latest firmware?

I bough mine December 2012 then after a while in 2015 I experience the same issue. At first, the volume slows down TO 0 automatic randomly and no one is controlling, have this annoying encounter 3 to 6 months I guess. Now its gone but appears another issue: it keeps turning ON/OFF random again on its own. Really BAD, I brought to the samsung service center but unable to find spare parts so no FIX. Its frustrating. I really hope that SAMSUNG can gives us link on how to resolve this.

I have yet to buy one and think I have a couple days left to do so. I did buy one on the last TV I had and never had to use it, so it was money thrown down the drain in my opinion. That particular Television (Sony) is over 6 years old and still works like a champ. Its really up to the buyer. It is a nice thing to have in case something does happen, but in my opinion if this HDTV doesnt last me at least 3 years without any issues I wont be buying any more Samsung models. Good luck with your decision and I think you are going to like the LN32A450.

Paul, call Samsung 800-726-7864 I think you may have a bad remote if when you click it on and your red light doesn't do anything on the TV. Also, the sensor on the TV is small, so be sure you are holding the remote straight and level towards the sensor which is whee the red light is. The remotes are a trip and they are touchy items. Good Luck! I hope this helped.

Ian, If the issue is that your Samsung TV won't turn on, which indicates you have the same issue with your model that I and others have had with different Samsung models, one or more capacitors in this kit may well work . . . if you feel you or a friend have the skills to replace the parts. However, there is just no way to guarantee it. My suggestion: Before ordering the kit, do a Google search for "Samsung LN52a650a1fxza won't turn on", or whatever your issue is, and see if the results apply to your situation.

I want to know the same question, I have a 46F6300 and would rather get this than the samsung HW-F450. Auto on/off and volume control with samsung tv remote is my concern

I had to send back. I hooked to an LG TV and the thing kept powering off by itself even after turning off the power saving features. I ended up buying an Onkyo LS3100 hooked it up using the fiber optic cable and it just works when I turn on/off and volume using the TV remote. It had LG already progrmed in I didn't even have fiddle with the remote.

Google the on/off problem, it's a well documented issue that can usually be fixed with simple firmware update. Try this thread for all things LNXXA550... www.avsforum.com/avs-vb/showthread.php?t=1020612

I have not experienced this problem with my TV. My TV is plugged in all the time and comes on/off each time I press the power button.

My LG problem was in the TV start up process. It didn't want to start. I googled the The LG model number and it was suggested that I must have some bad capisitors in the power supply. I ordered the kit, replaced the bad caps and now all is well.
