Samsung tv made loud noise and will not power up

Sounds like capacitor exploded. Check power supply area. Flat panel tv's use cheap capacitors. Most likely this capacitor is in the power supply area. The top will be popped, they're made to pop when they go bad. Have professional fix it.

I have a Samsung 55 in LCD tv that keeps powering on & off. I checked the caps & they look good and have the higher voltage rating of 25 volts not 12 volts. Any idea what the issue could be?

The capacitors can fail and show no outward signs. You need a special meter to check them. Without a schematic and voltage test points it would be hit and miss trying to find the bad part without the right test equipment.

Whats wrong with my Samsung 55" LN55B650 LN55B650T1F tv?

These are not meant to be repaired, just boards replaced.

Follow if you are able the AC voltage into the set and then when it changes to DC follow that---confirm all voltages are present, a total dead set usually means something open not too far from the power cord.

I have a Samsung LN55B650, and cannot use the remote to change channels, hav eto use cable remote. I change to TV mode, and program in channels, but that option is not available once I switch to HDMI2,...

OK the cable box remote is the only one that can change channels in this case. because you are using the tuner in the cable box not the TV.
all you need the TV remote for is to turn the TV on and off and turn the sound up and down. if you used the cable input on the TV then the tv remote would be used to change the channels.

Wont turn on. it is plugged in properly and remote has new batteries and lights up. Programmed to operate TV. No red pilot light illuminates on the TV.

If the front panel does not even light up, then you do not enevn has the standby 5vdc working at all. Power supply module will be the first place to look.

Why does my Samsung Ln55b650 give me a no signal when I switch to my ps3. Doesn't do it all the time.

It's just HDMI compatibility. Not a major concern, there's nothing wrong with the TV or PS3, they just don't play nicely together. You may want to contact Samsung regarding a firmware update for your TV. You may also find it on Samsung's website with instructions. They are very easy to perform. If this does not resolve the problem, the only solution you have remaining is to use the component cable connections from your TV to PS3.
