SHARP LC-46SB54u Problem

The frequency and color of the blinks will indicate the issue. There is a hold-down button sequence to try to backdoor your way into the set to see if the panel will light. You may have simply racked up too many "weird tuner faults" and need to reset it. My suspicion is that it's either that or bad panel backlight.

Unplug set, press and hold (on set) volume-down and channel-down and hold them while pluging in set. Will come on with "k" on screen, or will crash again if backlight bad. If it stays on, use your remote and arrow right then look for "fact init" and any other reset and turn them on. Arrow back up to "fact init" and hit enter. Let set recycle to green and unplug/re-plug in 5 seconds: the set should be in OOB state.

Hi Frank,

If you are referring to using your TV as the USB port... you cannot. It's strictly for service. I have tried as well and it won't recognize it. It's strictly for servicing.

Try removing set and or a box if used from power for several minutes.

has anyone had this problem? I was watching my sharp Aquos tv and all of a sudden I see a black line, then fuzzzy then black screen then a loud pop, now it looks like colors that sprawl out as if something exploded in one spot inside the screen and it looks like the inside screen is cracked. but nothing hit the tv. it just happend. the sharp people tell me that it cant be fixed or replaced. and they keep telling me i hit the tv! From 5 feet back??? I was watching it. he says..did you see anything strike the tv?? I was like, I am going to ignore that rediculous question because I was on my couch..and no one was in the room! he says the only way that happens is if someone hit it! OMG! i have only had this tv for 3 months and paid $2000 for it. why would I HIT my TV!! no one will help me. I have a master plan warranty on it aswell. they wont help me.

i believe your tv is getting overheated, possibly from dust getting onto the electronic components inside. or the inverter board for the lcd panel inside is going bad, alot of times it is the capacitors on the lcd inverter board going bad.
