Sound stopped

Please check to see if the tape is running. It is possible that the tape was running dry and created the sqeak with a static noise over the head. the belt would have failed then and stopped the tape movement. hence without the transport your song is not played. So please check this out. Otherwise it is important to clean the head and check if your amplifier is working. test for voltage and audio tone. if not confirmif the audio amp is faulty and replace. Hope this helps. Good day

Protection overload and the system shuts off

check your speaker wires for short, try to turn it on without speakers connected, if all connections and speakers seem ok the problem is internal witch can go from blown power supply to shorted output devices and everything in between , and as always look for repair shop in your area, do not attempt to do it yourself, fire hazard and electric shock are the things we all want to avoid ;)

Bel STi Short or Loose Connection

This most likely is due to a blown internal speaker which has shorted across its voice coil rather than becoming an open circuit. Bel/Escort now uses special "high temp" speakers which resolve any failing speaker issues due to higher temperatures. I assume that your STi is out of warranty. Yet, it will be worth it ($80) to have the speaker replaced and to have your STi flashed with the latest firmware which also gives the STi a true audio ramp-up rather than just the original slow or fast audio beeps to indicate the strength of the detected radar. The new firmware also includes slight performance enhancements, and includes better filtering for Autoscan mode. This latter enhanced Autoscan filtering makes the STi noticeably quieter while driving around town.

One speaker channel is crackly.

There is Definately a Short in the Amp if tapping Fixes it. Could try opening the amp and Inspecting the Back side of the Terminals. You can use a Voltometer and check the Wiring inside. Turn off Power Before doing this!

Won't stop scanning

L16 Disc coil needs adjustment, Audio is slightly off, and improper noise to DC squelch level detect used to stop scan on active channel. Set to an on freq signal like a NOAA weather channel, and useing a non-metallic tool, adjust to best sounding audio, probably less than a half turn either direction. An on freq signal moduated by 1000hertz, connect scope to speaker and adjust for highest undistorted recovered audio would be better if you could.

Poor/fragile connection

Yes, it sounds like the ports may be coming loose, I would attempt to return, if out of warranty, find someone that can solder well, i've replaced ports on external hard drives, not fun.

Sony amplifier problem

I has the exact same problem with the same reciever. It was the neg and positive wires getting too close. Don't join wires together to get the length you want. Make sure you use atleast 16ga wire with NO interconnections. My short went right through electical tape when turned up. ng

Sounds don't align with lip movement

if you are saying that your tv has no sound to match the lips movements then you will have to get a tech to repair your tv the problem is in the audio circuit could be a cap or the audio output ic.if you are saying that the tv has sound but it is not syncronizing with the lip movements have your tech check the sync circuit it is possible that the operating voltage is too small to allow the sync circuit to operate.good luck my friend.
