If it is not the afore mentioned remote or button issues, it is a defective IR amp sending the control IC signal from the logic amp to the OSD control. It is a Magnavox, not designed for the long haul.

Check this link to find the LJ41-02759A board for your TV. These boards fails quite often and the TV will power ON but with the same symptoms as yours.

Screen is black


sounds like it was enough to pop something in the tv, smell the back of the tv smell if anything smells burnt or hot. unplug the tv and let stand for about a hour unplugged then trying it again but if it does smell chances are you will have to see if your still under warrenty and have the unit replaced.

MAGNAVOX TV BURNING SMELL TV WENT POP AND WENT OFF


Well that pop had something to do with the power components inside the TV frying. I would have to say there is nothing you can do to repair it as its dangerous to work on such things.
I wouln't waste my time bringing it to a repair shop they will probably tell you to just buy a new one.

No setting or troubleshooting can fix this. TV needs service. Sounds like a control board or buffer board went out.

I have a 6 year old Samsung PCJ522R 52" TV.


It sounds like at least one of 3 "IHVT",s popped. in short, a "IHVT" is a high voltage transformer. It will have to be replaced along with any other parts that were damaged in the process.
They do produce a strong odor when they pop!!

It is repairable but at a price. there is a good chance that parts will have to be ordered.

you might consider buying a new LCD HDTV instead of fixing this one.
