There is something short inside the circuit board, may be a shorted transistor or so. Your TV need a through check up. Contact any service technician. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

SOURCE: no power no light sharp tv 21V-S300

This is a classic switchmode power supply, has sensed a severe potential problem, and is shutting down to avoid a fire, explosion, or both. This set had developed a problem, that is so severe that the set must be shut down, This set should be removed from the Power, and in my professional recommendation, you should get a "Quote" for repair, from, an, Approved Service Center, this point is very important for a good result, Always contact, their local, "Head Office" Now, when you get the information you want, then you can decide as to repair of replacement. The reason we want an approved agent, is that way, all the engineers are trained on their own brand sets, they have seen almost all faults, and will get the job done quicker, and for less cost, and usually have parts on hand, also sometimes, there has been a service bulletin in issued and the repair may be subsided or even free. There are many, many, many reasons that display this symptom, one must work through the troubleshooting steps to isolate and identify, the Cause and repair that and any damage done

SOURCE: i have a sharp tv model 21v-s100, if you turn on the tv. the fuse is always damage.

You have a direct short in the power supply or the high voltage stage, without more data it is hard to be more precise. But let us speculate, if the fuse blows right away, "power supply issues" If the fuse takes several seconds it is more than likely, " flyback problems "

My problem are channel going up automatic with out touch the button. the tv is sharp model 21V-FS700S


Check its front panel button [Ch Up] for a locked condition. If the micros-witch inside it has strucked, this kind of fault can occur. Replacing the micro-switch is the remedy. In rare cases, remote control might have sending fault signals. Hide the remote control from the vicinity of TV and make sure that the fault is not with the remote control fault signals.
