fixed my lcd tv with a bit of scotch tape
 

my 5 year old TLC 48'' TV was working ok
but this morning decided to double up the picture
every body had 4 eyes and two noses yuck!

so I went on the net to see if there was a fix
I have fixed a sony tube but HD wega tv by replacing chips [with u-tube guides]
that was a 10 buck repair but required de-sodering the chip and replacement
so this time the fix was free a sliver of scotch tape on a ribbon cable

most lcd/led tv's use common construction and layout
I see instructions for other brands and try one for sanyo [TLC makes screens for them]
there are two ribbon/cables one controls each side of the tv picture
located on the bottom center of the tv under a metal plate
so if you unplug one you get 1/2 screen
the good ribbon side will be clear and crisp
the bad one will be doubled
so on the outside edge of the bad ribbon connection place a sliver of tape
you have to try several sized tape bits to block the doubled input on the wires
my second try got I lucky with a 1/8'' sliver on the bad wires
that only blocks 2 or 3 wires but got rid of the doubling

we will see how long that fix works but you can't beat free fixes you can do yourself

I fixed a Sanyo 60" a few years back by replacing a control board, but it only lasted a few more months. I've had better luck with a Denon AVR, soldered in a fuse last year after losing the display. It's still going strong. After the experience with the Sanyo that went bad right off warranty, I buy TVs from Costco with the extended warranty.
