Pioneer has a power supply recall on some models. Do a search and you will find a number at Pioneer and they will replace your power supply for free. The loud popping noise and then nothing is a common problem with these. Hope this helps!

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years

I have a samsung plasma hp-r4262 the picture went out, I have sound but no picture! The day it went out it made a pop noise, then no picture! What could it be?


The problem of your plasma tv could be on power supply. The popping sound you heard maybe cause by blown capacitor. Unplug the tv from the main AC outlet then remove the back cover of your unit. Try to observe if there's a bulge up or leaky capacitor. If you see this bulge capacitor replace it. Be sure to observe proper position because it has polarity. To replace this bad capacitor you should be needing following tools: soldering iron, soldering lead and desoldering pump. Be sure not to connect separated pins when soldering. Let me know what you observe upon replacing the bad capacitor. Good day.

I heard a pop noise then picture went out. when i power on tv i get a red flashing light instead of greenlight in left corner of tv. I have a 2002 pioneer 50 inch plasma


The 'POP' noise was likely a capacitor saying farewell.

If you are able, AND confident with electrics - take the TV apart (UNPLUG)

These TVs are very heavily populated with Surface Mount components - I suspect that you will likely find - what looks like a small can (half a centimetre in diameter, with 'candyfloss' coming out of it..)
YES - You could get a replacement from somewhere like Maplin / Radioshack......
Replacement will work - However...you really need to establish WHY it went Pop, and get to the root cause (Excess power feed / drain)
Realistically - without sounding too negative . . other components would have also been affected but not necessarily killed.

Good Luck.

Had loud pop and then no picture on the vizio 50in. plasma


TV was on with no picture problem. Left the room and when I returned the picture was very dim. Turned system off and turned back on. Picture didn't change, but heard a loud pop from the back of the TV.

No picture


you may have missed the "POP". Common problem that makes your wallet lighter. search for "screen went pop" in the forums.

Microwave made loud popping noise


The magnetron is bad. Probably cost about $50 or $60 for the part. Not too easy to replace, but it can be done.
