If still under warranty or if you have no electronic repair experience take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. If the TV fell recently the following might apply to you: 1. Cracked circuit board very possible, try changing it. There is a very good chance that the circuit board has some broken traces. You would not be able to see this by eye unless this was very bad. The way to find this, is to troubleshoot the set on the bench to determine which stages are not working correctly, and pursue from there to find where the signal paths, or missing voltages are sourced from. If the set fell, there is also a good chance that the CRT is damaged inside. These tubes are extremely sensitive to being hit or jarred abruptly. I have seen a TV set banged against the side of a door frame while being moved, thus causing damage to the shadowmask of the tube. 2. Check for A/V input circuit board not seated all the way. If this board comes loose, your video will disappear. In case no violence disturbed you set: 1. It is very possible that something is changed in the user setup that is causing the no useable input condition. Check the owners manual and verify the proper user settings, especially the Tv-Guide settings for use with or without cable box or vcr if tv has that feature. 2. this is a fix for a similar set, might apply to yours: Try resoldering all 3 legs of q2300 the if amp transistor and usually pins 1-8 of u2300 the IF ic. This usually takes awhile because there are sometimes a lot of poor joints in that area of the board, look it over very carefully it usually fixes these sets. Good luck, and please try not to take any chances

look on the rear of the set and find out what chassis in your set.

SOURCE: my rca television works fine exept for the sound

There is a switch on the back of the TV that toggles between the built in speakers or the external speakers. Try flipping it and see what happens.

SOURCE: No sound on my RCA

May seem obvious but have you recently used the earphone jack this is the first thing I check with no sound as I have had a number go and not found out till I have jumped to the wrong conclusion ?.
Try your earphones and see if you have sound there , it will at least confirm that you have sound at the preamp stage .
If you have children check for foreign objects protruding from speakers ( not as uncommon as it sounds you would be amazed where I have found Kids toys ?or whats left of them ) should you find sound at the socket ease the plug gently back and fourth and youmay be lucky to reconnect the speakers . If no sound then your looking at calling an engineer to check out the sound Ic hope you are lucky .. regards Vortash
