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.

Do you smell anything burning. This happened to me and I cut it back on. It stayed on for 30 secs or so and did the same thing. After doing this 2-3 times, I smelled a burning. Being a member of the Fire Dept, I didn't want to see my buddy's coming to the house, so I unplugged it. The next day, I took it apart and there was a burnt resistor or something under neath the fan. I took it back and they gave me a new receiver, but I'm expecting the same with this one.

ProScan PS32500 32"-Picture has white static line & Static/burning smell


It sounds like the circuit board is arching over somewhere. It could be as simply as cleaning and digging out the carbon mark to stop the arching. This is most likely the screen or focus voltage causing this, if there are no parts that have broken down. This will damage the printed circuit board and make things worse the more you let this cook. This could be dangerous for you to mess with because of the high voltage present, so my best advise would be to get this into the repair shop as soon as possible before this board burns up. It should not cost all that much if the CRT board can be repaired. Good Luck
