cannot turn off closed caption on 27" insignia. the option screen which illustrates the closed caption category, is not highlighted and you cannot manually choose that option from the remote control.

AVI is just a format - the video inside it can be coded using just about every codec. That sharp supports files that are coded using DIVX 4 to 6 and XVID 0.8 to 1.3. You must make sure that the avi files were coded correctly. For that install this program and use it to check the files

I'm not sure if this is the same, but people were green no matter how i adjusted the tint, and lacked overall color. I doubled checked the component cables, taking each one out, and putting it back firmly,
Picture is back to normal. Easy fix.

According to SharpUSA the problem with the "Loss of Sync" error message is that (most probably) the cables (between the box and the display) are not connected properly (so remove and reconnect them carefully, on both units) or a cable is defective. 

Also, after you reconnect the cables try turning on the unit, if no success then depress the "clear" button on the external box (under the door on the front and on the bottom left and try turning on the TV again). 

It is, most likely, that the cables are not seated properly. Reseat the cables on both the display and the external box. 

Hopefully, this will clear the problem if still does not solves your problem just replace all the cables connected between .u can get the new cables at radioshack web site.just place an order they will provide you. thanks.

i was having these same problems with the screen going black, and i found that when i hit the back of my tv it would work sometimes. so, i improvised on some of the advice on this page and so far no problems. here is what i did (its very easy):

1. lay the tv on the floor and take off the back panel. (i think 12 screws)

2. on the right side of the tv (as you are looking at the back) you will notice a large metal covering that is held in place by 6 screws. unscrew these and remove the metal cover.

3. you will notice that the three screw holes on the left side of the board have some sort of metal or solder around them, in sort of a star pattern. when i looked closely i noticed that most of the metal (solder) was tarnished, or kind of blackened. (this must mean that the ground screws werent getting a good connection and this would explain why it would work sometimes when i hit it because it would vibrate the screws enough to get a good connection! )

so, take a pencil eraser and erase all the black or tarnish off the metal surrounding the screw holes. thats it! (to be safe i took some sandpaper and cleaned up the screw holes on the back of the metal covering, but i dont know if that was necessary)

at this point i followed another gentleman's advice to do a hard reset. this involved unplugging the 8 connections although i dont know if this was really necessary because i believe my problem was a ground issue. i did it just to be safe. his advice is on this site if you want to do this step.

4. i put everything back together and it worked! i performed a soft reset at this point which puts your tv back to factory settings. just go to menu>setup>reset>return to factory settings? yes
this will turn your tv off and back on. that's it. so far so good for me.

i hve the same problem. I turned on my Sharp Aquos lc-32d62u HDTV last night for the first time, but it is black and a blinking green light.
did you find a solution?

You have an intermittent power supply issue. See if you can get a used one on the cheap.

hi,

your main board or powersupply is faulty

or

One problem involves the lamp cage being loose. The fix is easy. All you do is remove the lamp and put it back in, making sure everything is tight. I guess they had a problem at the factory, for a while, not tightening the lamp cage. After a certain number of heating cycles, the lamp quits making connection.

thank you for using fixya,rate my answer

Try 0000 and 1234 as the PIN - the age old solution to problems such as this.

Failing that, google "Sharp Aquos LC-32G4U default pin" - that might get you a result, or at least point you closer to the solution.

If a PIN has been set up before, there will be a way of re-flashing a chip to default the PIN code. Again, google your model number for moe detailed help on your specific problem.
