Question about Samsung HP-R5052 50 in. Plasma HDTV
My tv model code: PS51D550C1RXXA SERIAL NO: 276039NBB01604V VERSION:1406
I see so many here with no sound/no picture issues:
1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signs of damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down the problem.
4. Be safe and if you do not know what you are doing don't open the set.
Answers to issues:
1. RE:fuses---if a blown fuse is found get a good replacement(not the generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put a higher rated amperage fuse in the set for any reason.
2. RE: power supply in set: if total dead aside from main fuse the set uses a standby power supply that runs 7/24 and a main supply (some are combined and some not.
Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and have no brown material coming out on top or bottom.
What happens in the standby area is they use caps with too low a voltage rating (saves money) which causes them to fail in a year or two---the standby runs 7/24 and the heat dries out the caps and they fail.
3. Trouble shooting consists of the above and then at some point you have to buy and try a board to see if it fixes it or not.
4. Safety first--no TV set is worth getting injured or even killed over. If set is opened at least look for puffed up and bad caps like in this photo.

most probably the fuse inside the circuit blown out, You should open the back of the tv to become circuit board visible. But this hard when novice do it.
To be sure that everything will be alright i would rather suggest you to bring the tv to the nearest service center. maybe warranty work for that.

First the main bd controls the "Turn on" sequences". When you press the Power on button the Main bd sends a "Turn on" signal to the Power supply. The clicking you hear is the Power on relay ativating. If the tv does not turn on and the relay keeps clicking then you might have a bad Main bd or there is s shorted board somewhere else in the set. The Power supply can also be bad. Have a trained Samsung tech troubleshoot the set.

Sorry, but welcome to the world of highly efficient, component-critical switching power supplies.
These are all of those things and the failure often is related to a specific type of component, an electrolytic capacitor. These are chemical devices and cheap ones fail easily, the most expensive take little longer but the primary value shrinks while the losses climb until the part cannot do what it should any more.
The main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core (no laminations as with a line-frequency part) transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.
Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself but it will likely have the same problem eventually unless they have altered the design.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

if you can do soldering work, replace two 1000uF10v bulging capacitor with 1000uF 16v or 25v in powersupply board. you will save $200.
