hi sir
as it is not giving the perfect picture so it might have gone wrong in the screen pixels better to check the lcd screen and me sure the pixels went wrong it can be also coz of the water vapours please keep the tv away from water or windows etc.there might be a circuit problem which may not be working .
thank you

I took it back to walmart and got a vizio hdtv instead.

no

I just sort out it.

Enter Service Mode InstructionsTV off, press mute 1 8 2 power, when TV comes on, you are in the service menu, To exit the svc menu power down the TV.

Check carefully the RCA conections or others.Sometimes this conections break inwards end cause this problems.Check also the lead and the Set up from surround sound.Verify if the TV has settings for this kind of operation. A strong hug !!!

Possibly due to the main inverter panel, take the numbers off and price one up they vary from £50 upwards

Seen an LCD like this before, sometimes it is from the display not repairable

Power supply related error, try and replace 1000uf 16v capacitor on power panel, if we was repairing the set would cost around £100.00

Try to tighten all screw around the power Supply to make a better ground ...

HOPE THIS WILL BE OF SOME HELP,TUNE IN YOUR TV AGAIN FROM SET UP......

DID YOU TRY PLUGGING YOUR COMPONENT CABLE INTO A SCART ADAPTOR FOR YOUR TV...THIS SHOULD FIX IT FOR YOU.... I TAKE IT YOUR TV IS A 5 SERIES OR A 6 SERIES SAMSUNG.. GREAT TVS HAVE ONE MYSELF, BETTER WHEN MORE CHANNELS ARE BROADCAST ON FULL HD BUT...

I TAKE IT YOUR WATCHING YOUR SKY BOX OR CABLE ETC THOUGH THIS TV..BUT YOU CANNOT NOT GET FREEVIEW..CHECK YOUR ARIEL PLUG GOING INTO THE BACK OF THE TV, THEN TUNE THE TV IN FOR DTV. NOT CABLE OR SKY ETC THEY WILL NOT NEED TUNED IN..THE MENU FOR DTV..IF THAT DOES NOT WORK..DO ALL THE OTHER TVS WORK OFF THE SAME ARIEL ON THE ROOF TO GET FREEVIEW ???

unplug it from the sky box

The fault lies with faulty capacitors on the power board,just had mine repaired.
the power board is easy to get to,just remove the back panel and its directly in
the middle.
The faulty capacitors are quite obvious as they start to bulge at the top
I sent mine to a company in Watford called gtvwatford 55 pounds for
the repair and now as good as new. pretty common with this lcd panel
im afraid makes you wonder on the quality of components used as
my hdmi input stopped working a while ago as well, so if anybody knows
how to repair that i would be interested,my panel is just 28 months old
hope this helps
