It was not your power board, Thought the same on several repairs.Found out it was the main board. The clicking was the tuner relay. I bet you own a SP-R4232. If so,The part you need is BN41-00574A. Also might be under BN94-00669A. Hard to find. Try Shop Jimmy/Or Encompass Parts. Not cheep tho. Hope this info helps.
Have a happy new year. Todd

SOURCE: i dropped my camera while the lens was out and now

That will be a mechanical problem and the camera is in a need of a repair.
Since you dropped the camera it is now Out of Warranty.
The repair of this model for this fault is about 48 pounds + shipping. KODAK also offers a Trade up option where you will have the opportunity to trade up to a newer model 25-30% cheaper than the market price.

Samsung pn50b550t2fxza. clicks on then clicks off.

When you talking about a plasma TV oftentimes use the main board but plasma TV architecture can indicate that other problems can go wrong you need to count the blink code on the front of the TV and read and not Google that it will put you in a better Direction most likely it is the poppers and the Z sauce but it could also be the ask ex zuz. Again counter blinking lights on the front of the TV and report them here then I think we can help you better

I have a Samsung PN51E530A3FZXA 51" plasma TV. I heard a pop & saw smoke from left rear of TV. TV went black & had no picture or sound, however the red power light stayed on.

Unfortunately plasma tvs are a lot more complex to service, instead of 2 or 3 boards there are a half dozen at least. I would guess when the main PS board went out it took some other boards with it. I don't have a manual for your set but I would look at the power supply sub boards, there generally are 2 of them, or on some models that is parts of the other boards. Generally there is a legend to see what voltages are supposed to be present at what places, samsung is good about making the test points on the boards. Also there are fuses on most the other boards and its possible one of those has blow, it won't be a typical fuse like your used to seeing, some are a small green component and some are white mini fuses...Good luck!

My samsung flat screen makes loud noise and wont turn on

sounds like a power supply board problem. Be careful. I would up plug it from the wall socket.. the sound u hear MIGHT be something on the circuit board heating up and about to POP. The power supply boards are not hard to replace. just make sure it is unplugged and be careful they can carry a charge even unplugged. Caps etc can Zap u.. as I tell every one , take picture of the insides of TV and the power supply board and a close up of all the numbers that is on the power supply. order the exact same part.. do not remove the bad board till u have the new one ready to go in.. good idea is use a grounding strap. the only cost a couple dollars or so.

PN50B550T2FXZA won't power up

The continous red light merely means power is getting to your TV. From your description, it is likely the internal power supply has failed

My 50"nplasma makes clicking noises

There is a problem with the power supply. The clicking is the power regulator continuously turning on and off. This was most likely caused by a power surge.

The first thing to check is a visual inspection of the power supply and look for bad capacitors. This can be done by looking for ones that look bubbled where the top metal part with the T is ballooning out. If you see any, replace these with the correct voltage and fared rating (both located on the capacitor itself) by soldering them onto the power supply.

This will fix the problem most of the time but the power surge could had also damaged other components in the power supply so if you are not comfortable with soldering or did not see any bubbled capicators, or replacing the capicators did not fix the problem replace the power supply board.
