Can some one send me a pic of what im supposed to look for?
There is a capacitor location number CP150 it is 2200 microfarad's at about 25v. it is located behind a heat-sink
near the middle of the board on the left(looking from back). if the
capacitor looks and fels like it is puffed on the top(it should be
completely flat) then that is the problem. you can replace with the
same value and most likely be good to go.

they are located inside the DM modules case( Metal Case on far left side ) open the metal case and you will see 7 caps on the DM power board. I am posting a pic of the board with the 7 caps that need replacement use 1000UF 25V caps to replace the 1000UF 16V caps that are currently installed.
Just check your main power supply socket. If it is ok than just open your tv back cover and check the fuse. I am sure the fuse is burnt. If the fuse is also ok than you need to consult a technition. But mostly it is the problem of burning fuse
There are 4 bad capacitors involved. It may not seem bulging but one or two are leaking. These are the 4 capacitors. 2 pcs. 470 microfarads - 25v 1 pc 1000 microfarads - 25v 1 pc 1000 microfarads - 10v I replaced them all. Next is to clean the board at the back. I got 91% alcohol and toothbrush and scrub. Concetrate on the 8-pin IC which has colored yellowish paste. Scrub or use a Q-tips buds soak with alcohol and clean it. Next resolder all 4 trasformers. Two on the primary and 2 from the inverter side. Also resolder the 2 transistor/mosfet (3 legs) which is attached to the metal (heat sink). After resoldering, again clean with alcohol by scrubbing or Q-tip buds for sensitive part.
Mine is working fine now. Good luck
This is the same issue I had AND....you can fix this by replacing 5 capacitors in the screen Power Board, So here we go: go to Radio Shack or similar store that sells capacitors and buy (3) 220 Microfarad capacitors Radio Shack Part Number 272-1029 and (2) 1000 Microfarad capacitors PN 272-1032. Now on your board you will see the bulging capacitors just remove them and replace them with the new ones. PAY CLOSE ATTENTION to the polarity, there is a negative stripe on the side of the capacitor. Make sure it goes back in the way the old one came out. Now the radio shack capacitors are 35vdc and the stock capacitors are 25vdc and the new capacitors are bigger in diameter but the difference is ok as long as the Microfarads are the same. Mine were replaced and all is well now
The 470uF/25V Caps are in the middle of the PCB alongside of the slab-looking aluminum heatsink. You should be able to see that the tops are popped up and the glue around them is brown from overheating.
