My sharp tv has a blotch on bottom of tv that is "dimmed" what could be causing that?

WITH NO TESTING IT WOULD ONLY BE A GUESS SORRY

H Anon,

How old is the TV? It could be a problem with the inverter or the LED/LCD panel. Try removing all cables from the screen for at least 15 minutes (including power) and then reconnect and power on the TV. Sometimes a dim spot can appear if the inverter isn't working correctly and dissipating any residual power can help.

Best of luck!

usually means its being pushed by something or the screen is warped, can also be impacted damage but its not broken the screen, check area with a flat edge. should see it then.

The inverter board is failing. Needs to be replaced.

try running the tv for a couple hrs on an all white picture, sometimes that helps get rid of some of the burn in. it has to be a pure white picture. snow might work... otherwise youre going to need a new panel

This, sadly is getting to be a very common problem with all Projection LCD TV's
Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses on one of the LCD panels themselves which are all located in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and visually inspecting the lamp itself and the lens that it shines onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly. Have a tech confirm-Get an estimate -Be sure to vote/rate me if this helped Thanks!

ON 1 OF THE OTHER SETTING PAGES YOU NEED TO CLICK ON ADVANCED AND GO FROM THERE....

if you can take the screen out , then use some dish soap,rag and water to clean the black blotch

if that don't work you may need to use something a little stronger , but not enough to hurt the screen
please rate a fixya and I'll be happy to assist you in the cleaning process and care of the screen

usually these are caused by cleaning the screen with a damp cloth or fkuid rear projection tv's usually have two plastic screens separated by about quarter inch with bulbs between,one being a magnified screen.problem is,condensation can occur causing various blotches,letting the screens naturly dry out usually solves this but failing this you have to strip down and wipe them with clean dry cloth.be careful though the inside screen is very delicate.

Could be color wheel problem--but u'll prolly have to change out the light engine $$$--Causes blotches---Good luck
