My sharp tv is flashing colours how do I fix this issue

You will need to preform a power drain cycle on your TV here.Unplug your TV from the power source.Press and hold the power button for about 10 to 30 seconds.This will help drain all of the TVs residual power. Now plug the TV back into the power sources.

bad blue on control board or bad screen

Thank you Much. I called SHARP for service code reading with absolutely NO help. Was told to call a service tech. I can fix this and at least know what to look for.

Unplug it hold down the Channel Down button and the Volume Up button unplug it for 10 seconds then plug it back in and continue holding them down for another 10 seconds then release. I had the same issue and this fixed it now I have another though *~*

I've read online that upgrading to the latest firmware sometimes resolves this issue. That's kind of shooting in the dark though - I personally would not feel completely confident that a FW flash would actually resolve the issue (as it could still be lurking beneath somewhere, waiting to surface again). If you have no warranty, then the FW flash is not a bad option. It's relatively easy and virtually impossible to screw up!

If you're still under warranty, then I imagine you've figured out by now that you'll need to contact Sharp to fix this issue. Mine was luckily under the extended (15-month) factory warranty when this first happened to me. I was 13+ months out from date of purchase. Sharp support confirmed a tech needed to come out for an all-day appointment to troubleshoot the TV. Thank goodness for the extra 3 month warranty I got when signing up for the Aquos Advantage club! Otherwise, my $3400 investment might have cost me at least $700-$800 to fix - only a year out from purchase!

Good luck!

if the tv is still under the manufactuer warranty i would definitly give them a call. If it is a Sharp tv I would call the 1-87-BESHARP. I would also try unplugging the tv for at least 2-3 minutes and seeing if the tv will reset itself. Usually what happens with these tv's when the light blinks it locks the tv as a security issue. If the unplug does not help it will more than likely need service to get this fixed for you. The call line hours are M-F 7am-7pm S-S 9-5 and they will be glad to help you from there.

have you checked the TV's Settings ? chances are the colour settings could be changed and the colours could be turned right down ?

if not, goto the sharp website at http://www.sharp.co.uk/pcat/support or www.sharpusa.com/products/support/ depending which country you are from. and see if they can solve your issue !

Hope this Helps !?

If your TV is not too ancient there should be a button that says auto set or return to default or default....try it. Tango....and hope this helps.
