I took apart the back and found a unit with a ballast and a lamp on it, there was a blown 2A fuse. I changed the fuse and the TV worked for a couple of minutes before it blew again. Please help, thanks!

Hello Check whether the lamp life hours are going to be out. Refer to its user manual for details. DLP chips fault is very rare; unless you have handled them very carefully. Check the lamp and BALLAST baord that supplies voltage to lamp. Picture of the ballast baord to your TV is attached.
This set, I am sorry to say has no bulb and has no ballast circuit. There are three picture tubes inside this TV set. What exactly was the part you pulled out? Can you post a picture of the Part you pulled out?
It is quite likely that the lamp is defective. The whirring sound is possibly the fan doing its cool down cycle. If the lamp has failed, it is likely that you may need a ballast unit as well as a lamp.
If the capacitor on the ballast was puffed up or blown up you have to replace the lamp, ballast & SMPS at the same time. But if the ballast is not trying to fire the lamp it sounds like the color wheel is not coming up to speed. If this is the case, the set will not turn on.
I just bought one of these "dead" units for $15...I replaced the blown 2A 250V fuse with a new 2A fuse and it blew as soon as I plugged it in so then I took one of the 4A 250V fuses from the other side of the unit(located right behind the speaker output terminals) and it works perfectly now.
Rulds2008 is probably right. I had the same problem, but have no TV repair shop near me. So since I have experience fixing computers, I decided to repair the TV myself. I initially repaired the Lamp, but the TV still flashed all three lights. Called Samsung and they told me that I might need to replace the ballast, but it would be best to bring it to a repair shop. The repair shop offered to come out and look at it for $150 or bring it in for $120, even though they were about 30 mins away. Ordered both parts on www.Samsungparts.com and got them in three days. Still had the three flashing lights. Took apart the entire TV (googled it on youtube) and vacuumed and dusted the TV and took apart the color wheel (about 20-30 mins). It was completed busted. Found out that if the color wheel is broken, it will not send a signal to the ballast to tell it to start up and power the lamp. So if you have replaced the lamp and/ or the ballast and it does not light up, it is more than likely that it is your color wheel (buy it on ebay or amazon, got it in three days versus a 3-4 week back order on company sites). Also, make sure the power switch on back is being pushed upwards and not downwards or the TV also will not start. Total parts cost me ($400) versus having someone else fix it and charge me double with labor and parts. TV is better than ever. Hope this helps.
Hello! Lamp or ballast(if lamp has been replaced) is bad. Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it! Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first! Good luck, Alex.
