Thats either the flyback or the HV splitter. If the sound is coming from the rear left side its the flyback. If its coming from the front of the set its the HV splitter. They are both easy to replace. I will post a link where you can get replacements with instructions if you would like.

If this is similar to the d52w20 then I almost garantee you need to replace a capacitor. You can check to make sure that's what you need by unplugging the tv, taking off the back cover and feeling the top of 3 capacitors. On my d52w20, CP150 (rated at 2200uf 16V) was blown and the top was bulged out. You should also check CP120 and CP114 to see if either are blown. I don't have a clear picture of where it's located, but I have a picture of what you should see after you take off the back cover.

In the middle of the picture you see an aluminum heatsink in the shape of a 'C' with the opening facing away from you. That is where CP150 is located. CP120 and CP114 should be located nearby, but if you can feel a bulge on any of the tops of those 3 capacitors replacing them should fix your problem. Replace the existing capacitors with a higher voltage rating of either 25v or 35v.

"4 capacitors on the power/deflection board. CP110 220uf 200v. CP120 220uf 35 Volts. CP114 220uf 35 volts. CP150 2200 16 volt. also check entire delfection board for cold solder especially around flyback. bad connections here can cause problems like some of the fp fuses blowing and cutting off convergence supply"

Your TV is overheating.. easiest remedy is to point a fan at the back of the TV or... clean the inside of the TV, Im sure its full of dust and stuff... this prevents air circulation inside the TV thus creating more heat...

SOURCE: RCA R52WH74 that will shut itself off

Replace 3 capacitors on Deflection board its the bottom left hand side cp150 200uf 16v use 25v capacitor and cp114 cp120 in same circuit 220uf 35v. You will see cap cp150 if it is puffed up on top they are Bad. Call Mats Electronis 1-800-628-1118 Radio shack might have capacitors.
