It started with a whirring/grinding sound, like something was having a hard time spinning, then the colors got blotchy, until eventually the screen went black. I unplugged it and shut it off for the night (it had been on all day) and this morning it worked fine. I turned it on again this afternoon and about 2 hours later, I started to hear the "whirring" again, the picture was fine, but I shut the TV off anyway. How expensive of a fix will this be?? Is it something I can do myself?

Hi,If your tv is a dlp you might be experimenting a color wheel problem.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming ,grinding,buzzing noises.
This could be your video board going bad where your input cables are connected --OR-- the color wheel going bad. Hard to tell without a photo or reference though. Try swapping the cables first... and listen for any winding or whirring sounds.
This is a simple fix and not hard to do, first you must get the speaker grill off, usaly two screws on the bottom and they might be hidden under to caps, then remove the acsess cover from the front. From there you should see a control box with six controls, three on top of three,,,,One part label "screen" the other "focus" now turn the set on and tune to a input that HAS NO SIGNAL this should give you a black pix, probley not now but it's supose to be black. Now turn the ones marked screen , one at a time counter clockwise just a little to get the pix compleatly black, now starting with one color turn the control slowly clockwise till the color just appears then turn it back down till it just disapears (Black) do this for all three colors Now the set should runn
If you are hearing this noises,that's your Color Wheel. The reason fot that is because your color wheel spins 5000rpms(revolution per minute) and something that modifies the balance if the disc can cause different things.Unfortunately in order to check if your color wheel is working properly you need to open your TV and physically check out.
Grinding= Most probably the color disc is broken and you need to replace it.
Spinning / Buzzing = The bearing of the wheel is loose and is loosing its balance,eventually it will brake.
The best thing to do is to take the color wheel out and spin it ,if you feel that the disc kind of wobbles or doesn't spin smoothly you have to replace it.
You can check DM they have very good prices

It sounds like it is the Color Wheel. I do not think you can get the Color Wheel separate from the Optical Engine like you can with Samsung. RCA is very tight with there parts like that. Because you have to get the whole
Engine Assy, cost would be too much in my opinion to invest into it. The part cost approx 800.00 the last time I checked on one.
I Hope this helped,
If you hear a grinding,whirling,spining or buzzing sound, that sounds to me like the COLOR WHEEL,the reason for that is because your color wheel spins at 5,000 rpms(revolution per minute) and something that modifies the balance of the disc can cause different things,Unfortionatelly the only way to check that the color wheel is working properlyis you need to check it out physically
I did some research and I found the color wheel at DM;http://www.discount-merchant.com/Samsung-Replacement-Color-Wheel-HLS-HLT-Series-p/samsungcolor_wheel_bp96-01579a.htm?CLICK=52978
Sounds like the same problem I had, I bought a new bulb as well, installed it and nothing. I googled that same issue and endedup buying a kit herehttp://servicemanuals.vstore.ca/product_info.php/pName/mitsubishi-v26-dlp-power-pwb-repair-kit/cName/repair-kits/osCsid/145ffde26a9336eaf57c21ff6389def7that came with capacitors that had to be replace, the kit comes with aservice manual and a bag with lots of different capacitors to replaceany out on your board, they are really good at troubleshooting and theyoffer help online. If that is whats wrong with you, you will need asoldering tool, I bought my as a kit at radio shack for $20.00 and plusthe $36.00 for the kit, and a lot of patience, my TV is well andrunning now, it was better than the $600.00 estimate I got from a localrepair shop. Good luck!
