Looks like you will need an optional cable - a Digital Audio Out Optical cable. You can buy one at Radio Shack, Best Buy, most department stores that sell TVs.. Ref to pg 12 of the user manual..

Even if the capacitor seems ok, they are often not. Replace them or buy a new power module. Or bring it to the nearest serviceshop.

Hi Fahim
From your description about the problem you faces with this TV; it sounds that the back-light inverter board or the related part is faulty. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.
IT WILL BE BEST TO CONTACT ANY OTHER SERVICE TECHNICIAN. AS YOU HEARD, ALL TECHNICIANS AT SAMSUNG AUTHORIZED SERVICE CENTER ARE NOT SO TRAINED WELL; AS THEY CLAIMS.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Other than the power supply, it could be a cold solder joint on one of the PCBs. Easy to fix, but almost impossible to find.
