SOURCE: 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.

SOURCE: on one minute then POP loud noise, burning smell

Loud popping and loss of power is common on plasma TVs and is usually either the Y sustain or Z sustain boards or buffers; in these instances the damaged part will be quite evident.

If this is an LCD you might have degraded insulation on one of the pink/blue backlight power leads causing high voltage to 'arc' to the chassis.

The loud bang and smell is actually to your advantage as in these circumstances the damaged part is usually evident. It'll just be a matter of popping the back off and sleuthing around. :)

SOURCE: Burning plastic smell

Hi, Sounds like something is wrong. Is this a gas or electric oven? Did you have to change settings from natural gas to lp?
Please let me know, I would like to try and help you.

Five buck solution; If you have any tek skills at all and are feeling adventurous; UNPLUG THE POWER, remove the back panel; You will be faced with the mainboard. In the lower right quadrant you will see two small capacitors, like tiny yellowish coke cans. If these are bulging, there lies your problem. These must be replaced. If you have no soldering skills, take only the mainboard to a fixit shop and have them solder in the two capacitors easily found on line. No guarantee's but worth a try

I have a philips 42pf55000.switches off ,renove mains ,comes on again ,but no burning smell


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

No picture and burning smell from left side


Bad COF ic on buffer board. Can usually tell which one's bad. It will look overheated or a hole in top of ic. Look at upper and lower buffer boards to see which ic is bad. Can get from Encompas Parts, Recommended replace y sustain with buffer.

Seal deal w/ ours. I took it apart and the power supply board had the burn marks on it. Just ordered another power supply board (pn: 272217100571) for ~ $100. TV back panel comes off fairly easily to get at boards.

Picture focus and color


Your TV set just blew out whats called the convergence IC's. These, both (2 IC's) will need to be replaced, and since you smelled something burning, there are most likely bad resistors as well on this board. You will need also a service manual for sure to do touch-up convergence alighnments. If you do not have any electronic serviceing experieng or any knoledge on repairing printed circuit boards, Play it safe and call in a pro to assist you with this repair. Safety is Number one on the list! Good Luck
