Numerous white spots on Smasung DLP TV

If your Mitsubishi TV has white spots in the picture , you can call Mitsubishi @ 1-800-332-2119 and request a free DLP Chip to fix the problem. They will send the New DLP Chip at no charge to a TV Tech in your area to install it for $200 flat rate. That is about a $250 savings if you had to pay for the chip . Call them with your TV's Model number and serial number and let them know when and where you bought the TV.
It saved me some hard earned money and now my TV is like New !

My JVC 56G787 is dark and bright is turned all the way up

You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

Dark band on left side, Samsung HL-R5668W

the reflecting mirror is likely loose and falling down inside the light reflecting tube. you should have seen the band getting darker and larger,
the small mirror is in front of the lamp and bends the light,
remove the lamp and look down the tube (light path)

how dark? can you see anything throught the shading.. still might be a cap in the video out circuit but the one Im thinking of shades the right side and brightens the left.

sometimes RF or HV arching causes shading on left, mute your sound and listen for sizzle noise in the back.

I have have this TV for almost 3 have a shaded area on the left side

The dark side of the screen causes of the lamp alignment or prism glass alignment. This is critical you have to consult your LG technician to do this. But if you have any background o repair consult the service manual. Please careful not to touch the prism quarts so that you maintained the clarity of picture and brightness on the screen.
