there is "audio out" jacks on back side of television. connect it to an amplifier or other tv & hear if sound is comming. if sound is comming then audio amplifier is defective in your tv. if sound is not comming then audio processor may be defective.

This is a common fault solution which can be checked and corrected by you assuming that there is no component failure . There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Check for tips to look into the SMPS unit:

Hi nmolina505,
Your unit is capable of receiving DTV 480p and 1080i format and will automatically configured by the system when switching to DTV mode. Make sure that the cable connected to y,Pb, and Pr video output of set-top box are properly attached to your unit. Double check the connections and your cable wires. There is no such pincushion adjustment in your set-up menu.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Except for you buying the parts and doing the repair-----Yes! to a point..

you need to general service the whole unit. this will include re-soldering and changing some defective components from the board, which has been damaged through using from past years. my advice is to have a quotation from service tech and then think about repairing it..if it is better to buy a new one..

You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

Samsung has had a issue with several models, with power supply going out. The clicking noise is what lets you know it is the power supply, it is teying to cut on but has not power from the board so it cuts off. I would call Samsung and see if your model happens to be listed as the models they are covering the power supply for, your exact model number is HCM553WX. If that model is not on the list of covered models, you can ask Samsung what to do, because parts for your tv are no longer available. Hope this helps. You can reach Samsung at 1-800-726-7864
