TV makes a spinning noise coming from the lower right side.

Sounds like the Y buffer board upper and/or lower are going bad

I have a Sansui LED T.V./monitor Model HDLCD1909, every time!I've turned it on here today it just seems dark n over redded, also I do believe that I had it working a short time last night, I have NO REMOTE and want to 'Hard Rest entire Television System.

Start simple by using different cables, whether they be HDMI, VGA or standard COAX cables. They could be losing the connection. Also, it's possible the power supply is wearing out and it gets too hot. You might want to simply try some spray air duster type thing to clear out any dust that can make it hot.

Have someone check the u joint in the cv shaft for that wheel.. they make a clicking noise when 4wd is engaged.. it puts a load on the shaft.. .. often cheaper to just replace the cv shaft

look under for debris or bent or damaged components jack up truck if loose or making noise check shocks [2] move[push against] tire up and down if loose check upper and lower ball joints[3] --push side to side if loose check tie rods steering components [4]spin wheel look for damage by cv axle or[5] if noise behind wheel possible hub [wheel bearing damage remove wheel and inspect hub

Check your power cable. Unplug it from both ends and plug it back in

If still under warranty, I would suggest going that way as this is a bad matrix driver....

Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

your bulb has burnt out

Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.
