I knocked my westinghouse ltv-19w6 off my dresser
You have to open it up to rectify this fault ofcourse. Due to hard hits, microswitches inside it may got damaged. Microswithces are the contact points when you operate the tV by the front panel. they can be located just behind the front panel switches, and inside your tV. To access it you have to open your TVs back cover. It is easy to locate these, and these will be small square shaped switches, directly soldered to a printed circuit board, and fitted on the front panel side of your tv. If anyome of these got strucked due to any hard hit, the whole front panel controls won't work; including remote sensor. You can also see the infrared remote sensor on that board. This is a three terminal part, usually look black in colour, there is a number laser printed printed on its side, and should be noted when you go to buy a new one. Replace the all microswitches at the same time. They are easly available, and cheap also. Desolder one amoung them and keep it in hand as a sample when you go to buy them, because there are so many types, differ each other in diamension and pin confuguration. Note for any printed circuit board breack or crack happend due the fall. If so, just bridge the cracks with a nice piece of copper wire, or two or three twisted copper strands from a wire. That is enough if there is a cracked. Normally this printed circuit board cannot be available. So repair it, if it has crack on it. Just examine very keenly for crak, as these may be sometimes microscopic.
