Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.

SOURCE: My Sharp LC-26D6U has lost Audio. How can I fix

Almost all intermittent audio or audio failure problems with Sharp Aquos LC**D4U, LC**D5U, LC**D6U, and LC**D7U televisions are the result of a relatively simple design flaw involving the heatsink pad compound used on the Tripath TA-2024 amplifier chip (IC2502) found on the A/V board. This compound has a fairly low melting point and, over time, tends to seep out from between both top and bottom heatsinks onto the legs of this chip as well as onto circuitry immediately surrounding it. Further, over time the seeping compound also becomes somewhat conductive creating bridges which short the audio amplifier circuit causing everything from intermittent audio to complete audio failure. Fortunately, in almost every case audio can be completely restored by cleaning the old compound from both top/bottom heatsinks and from both sides of the PC board in the area immediately surrounding the chip (I used rubbing alcohol which worked quite well). Sharp has issued a service bulletin addressing this issue (LCDTV-194) wherein a ?2502 Heat Kit? is specified. This kit is Sharp Part Number: PSPKIT663WJZZ and is available from partstore.com for $19.95. However, it?s entirely possible to get by with the heat pad only, Sharp Part Number: PSPAZA663WJKZ for only $9.95, also from partstore.com. Please note that board replacement for this problem is almost never necessary, so if you?re working with a repair technician be sure and insist that he/she be certain to try cleaning the old board and replacing the aforementioned heatsink pads before charging you for a new board. If one is reasonably familiar with electronics disassembly/reassembly and is willing to take their time, this can even be a DIY project. It is possible to find ?important service references? by simply entering LC26D4U (the 5, 6, and 7 series are very similar, and this information covers all screen sizes) into the search field at eserviceinfo.com. This will greatly aid in disassembly/reassembly of the TV, as the A/V board is somewhat ?buried? under other boards. Please also refer to post # 373 at: avsforum.com/avs-vb/showthread.php?t=647174&page=13 for some ?pics? of the information detailed here. My knowledge of how to solve this issue came primarily from finding the research efforts of ?Aureius? on the AVS forums, and particularly from his taking the time to post the solution publicly so that others might save time, money, and aggravation. I'm just passing along the information. Thanks Andy! I also wanted to mention that a couple of other very pesky common problems with these series of Sharp TV's involving symptoms of random powering-off and/or powering-on, and 'function lock-ups' of various sorts are easily remedied through two firmware updates (Main CPU: PH1UU112, Monitor: MD1UA104). These are not available to end-users via the internet but it may be possible to get the files from an understanding factory-authorized repair tech. They are installed using an SD memory card (don't use the HC high capacity sort, use only those that are NOT HC) which is inserted into a special slot in the back of the machine. For those of the DIY persuasion, information about how to check whether your TV has old firmware in need of an upgrade is readily available through internet search.

You can do it two ways, one, if you desktop has just VGA (blue,15 pin) connector, the other way, if your desktop has DVI out, then you will need DVI to HDMI cable.

This is not a power supply issue. There are few other possibilities. However, kindly provide more details :-

1. Does the screen remains dark with ' Please wait ' on it or the brightness and everything is correct?

Sir try to check the cables connection at the back of your tv. and if you are using a digital receiver, try to use a dvd to check if there is a sound. If there is a sound the problem is the digital receiver, feel free to send feed back good day and best regards.

Yes the repair will be more than the 19" LCD TV, most of the time the HDMI circuits is part of the main board which is basically the main part of the whole TV as you can see here:
