The capacitors are of rating like 1000mfd 25V. If you replace them by yourself, make sure that 1000mfd(microfarad) remains constant and the voltage is atleast 25V. A bulged capacitor looks like the one in the image below.
If you wish to take it to a repair shop it would cost you around $200-$250. You can use http://national.citysearch.com/ and search for "TV Repair"(without quotes) in your area.Or you can use http://www.tvrepairpros.com/Or you can buy the parts using the part no. I always recommend my clients to contact dealer before making a purchase. If you want to repair it yourself then you should be having proper knowledge about the internal circuitry of the TV.You should also require a multimeter and soldering equipments and schematics.
Take photographs or mental picture of connections with power board before replacing so that it won't be confusing later. I'm sorry there is no easy fix or press-a-button fix. This is an internal failure. Click on the highlighted word below for the link to open.
