I turned on my tv this morning and it started smoking and of course smelling like something inside was burning. We took off the back and can see nothing that looks burnt or melted but the tv still wont...

may be ur tvs lamp side have some problem. may be the lamp over heated and burned. just open its lamp cover ann check it.
also check its power supply input point(near fuse) there is an MOV (used for voltage surge protection) is burned or not. if there is any voltage surge it will get shorted and the fuse will blow off, protect the power supply for any further damage. check the fuse also. if found open then check the MOV. insert fuse only after replacing the MOV.

Why is there white dots appearing on my expensive 61 inch samsung. First it was 2 dots 5 days ago now there are 5 spots and counting.

It sounds like the mirror array is playing up. Maybe caused, as it is mechanical, by dust.
If it is still under warranty, I would have it looked at, if not request a Samsung Authorised DLP Technician takes a look for you. If you are in Europe Samsung may look at it with a view to helping when it comes to repair cost.
Good luck

Thanks for using FixYa. You’ll need to reset the Projection TV and to reset it follow these steps:

  1. Turn off the television and wait for 5 minutes.

2. After 5 minutes unplug the television power cord from the electrical outlet.

3. Let the television remain without power for more then 1 minute.

4. Plug the power cord back into the electrical outlet. If the television is plugged into a power surge protector, remove it from there and plug it directly into the wall outlet. Turn on the television. If the issue is resolved, then the problem is with the power surge protector and not the television.

If the issue is not resolved then this might have happened due to over-voltage. Please check the power supply unit for swollen/bulged capacitors and burnt wires/components on the power supply board of your TV. You should try and turn off the TV for 8-10 hours to reset it. Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition. All this is only recommended if you have electrical expertise and know how to solder/re-solder components.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Samsung hln5065 picture issue

If all 3 lights are blinking on Samsung DLP it means your lamp is burnt out or has issues. The manual says replace the lamp when all 3 lights are blinking. If you can hear the arc from the ballast the lamp should light if the lamp is operational.A new lamp should solve your problem.
