The problem is with the voltage capacitors and transformers on power circuit board.Some of them has burnt off and so only you are having this smell and popping sound.You have to take voltage readings and test power supply components such as bridge rectifiers and capacitors. If there is no voltage rating you need to replace that part if not you have to check the soldering joints and solder it again.

RCA HD50LPW164 turned on TV made a pop


the loud pop you heard was probably a capacitor blowing its top. The grinding noise is likely high voltage arching that was occuring due to rising voltage since capacitor isn't there to smooth it out.

Most likely the power supply is failing.

TVs have protection circuits to prevent full power-on if a fault is found in the high-voltage and/or high-current section of the circuitry to prevent something bad from happening, like a fire or sparks/smoke.

Loud popping noise and spark coming from red projector


I would guess you have a High Voltage Leak at the Anode Lead Cap where it Mounts to the CRT. This is not a area to mess with You are better off calling a professional to fix it. It may be a little difficult to confirm if it is a intermittent problem.
Hope this helps,

Tv went out after loud pop and has clicking noise does not turn on


If you have a Sony DLP, then the loud pop you heard is your lamp.  The lamps last approx. 4K-6K viewing hours.  Read your manual for replacement part number to reorder and very simple to replace yourself.

Loud popping noise


The 23" CRT set may have a high voltage breakdown in the flyback transformer or focus divider. Take the back off and operate the set in a dark room. Look for anything that has a blue glow around it or sparks flying when the pop occurs. I won't guarantee this will find your problem, but it is definitive if you see these!

I once had a set with these symptoms. I stopped the blue glow and arcing by covering the focus divider with epoxy. It worked for a couple of months before the divider literally broke apart.
