you possibly have bulged capacitors or loose connectors..or also you possibly have faulty t-con board.

Hi, welcome to Fixya!The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.All these can be checked on the power supply board.But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.I hope this helps.Good luck

I don't yet have a solution for this problem, As I to have the Sharp model LC 32SH12U 32 inch LCD Tv. From what I have seen and read in searching for a relatively cheaper fix than just tossing out this $600.00 Tv,I have heard T-CON Board MANY MANY times now up until today I had a guy tell me that he was pretty certain that it is the SCREEN PANEL!!! I wouldn't think that if the screen was bad it's self it would show ANY colors or tints, Lines or what have you..I just think the T-CON Board is gone bad in this Tv As it has perfect sound, And like most everyone elses for a while after my TV warmed up it would play like a champ and had a BEAUTIFUL PICTURE until now I think the T-CON Board has gone completely out on it. Sharp must have undoubtably purchased ton's of BAD T-CON Boards that fit not only this TV but also the AOC,DYNEX,INSIGNIA,And Vizio Brand's of LCD TV's...The VERY Same T-CON board which is Part Number X3562TP ,Is futted in every one of these same brands of TV's And I feel they have gone bad in Thousands of LCD TV's and it has Obviously caused thousands of people some very bad issues with their entertainment products..my wife and I are TV Folk and that is what we do...WE watch TV,,And now that our Main TV is broken and we can't really afford to just go out and Buy a new one I have to try and repair this one,And as Cheaply as I can, So I may be about to waste $40.00 on a T-CON Board, But hey I gotta KNOW..If this don't fix it, Im just gonna part the TV out on EBAY and go for another brand of TV..I thought SHARP was a really good brand of TV, But from what I have learned..our money would have been better spent on a different brand of TV!!! If this DOES repair our Tv I will be certain to come back and let everyone know!!

There are several processors in the tv, and it sounds as if you have one that is going out, or on its last leg. I would recommend that you take it to a tv repair shop and have it fixed. The cost of a repair is less than the cost of a new tv, thus making it worth the money.

There is a separate fuse inside for sound, but not the only possible solution.

I don't have a solution but starting 2 weeks ago I have the exact same problem. Test different devices and cables and it points back to the TV. Anybody have a solution?
