Fisher makes quality equipment that will provide entertainment for a long time, but as with any electronic device, transistors may burn out, fuses might blow, motherboards could fry and switches may break. This can especially be the case when components are overworked, causing excessive heat to build up. Fisher equipment isn't solely made up of electronics though, and problems can also occur on a mechanical level.
Receivers can experience electronic failure from overuse. Plus, they can have switches and buttons break on the faceplate, leaving you unable to select different features.
Amplifiers are sensitive to cross connections and loose ground wires in other components. The amp will emit a humming noise that can drown out the audio in some cases.
VCRs are an older technology that is much more reliant on mechanical and analog parts and will likely therefore have breakdowns in these areas. The mechanism that plays tapes is complex and has a lot of small moving parts that can break or become misaligned.
Speakers can be blown out if played at excessive volumes. Look for physical damage on the outer part of the speaker.
Camcorders can experience quick battery drain as the battery ages. They're also prone to lens damage from drops and falls.
Reasons why your television screen won't work
Depending on what's wrong with your television screen, there are a few possible causes for its malfunction. If your screen gets a static image burned into it, then there are a couple of programs out there that will attempt to repair the burned screen fragments. An alternative course is to run your television for 12 to 24 hours with static snow on the screen. If there are lines or discoloration on the screen, then it could be that the screen is broken. It also might be a connection problem with other components or the service provider. If the screen is black but the television is on, then either the screen is burned out or there are problems on the circuit board that need to be addressed. A multimeter can help you narrow down which electronic part is faulty.
