The high pitch squeal you hear is usually caused by a coil vibrating, normally in the horizontal circuit. I've also seen the ferrite bead on the horizontal output transistor do this, but, it is rare. I normally will repair this by finding the coil and "tightening" it. To tighten a coil, technicians use different chemicals, such as, a hot glue gun, rubber silicone or even finger nail polish. I will find the coil that screams by starting with the usual suspects and using a wooden dowel, barely touch the coil and if the pitch of the noise changes, then, thats the coil that needs repaired. If you do not know your way around the inside of a television, I never recommend you do so, since, this procedure must be done with the set turned on and you poke your hands around the inside of the set by the high voltage circuit. Hope this helps your decision.

My watch stops working, the mechanism works on motion or kinetics. However, even with a bit of a shake it works for a bit then loses time and stops altogether


It may require rather more than a bit of a shake! Some makers say that you have to swing it gently form side to side for 200-300 times to fully wind up the watch.

I bought one some years ago that didn't work well and I had it cleaned, after which it worked perfectly for years.

If giving your watch the shaking I described above it still does not work, try having it cleaned.

Automatic watches thrive on being used but should run for 2-3 days before stopping.

Your pitch control is faulty or dry. Try spraying wd 40 into the pitch sliding hole form top to bottom. Dont over spray it. Just a bit from top to bottom will do. If issue still persists, then there's some capacitors are weak which controls this pitch.

Original circa 1982 Kurzweil Ensemble Grand upright, has been working just fine until today. At first the (grand piano) sound had just become very distorted or seemed to have messed up sustain or echoing....


Given its age, this unit needs a little TLC. Units of that vintage used some capacitors that may have dried out a bit and need to be replaced. There are also op-amp ICs internally that may be defective. I would suggest a visit to a service shop that works on keyboards as not all do.

Keep us posted.

HIgh pitched sound when accelerating w/ My 2007 Hyundai santa fe


This may sound strange but have someone check out your radio system. Sometimes an antenna wire or wires, when jared loose will make that ear piercing noise. It may not be the problem but it's worth looking into.

Sound wavers (speeds up and slows down)


you need to replace the Pitch controls. I'm presuming it is a sliding pitch control. Use the Red start stop lights that reflect on the rotating wheel. put the pitch in center 0. does one row of the dots on the wheel stay completely still.now just turn it up op down a bit until it starts to move the dots slightly. now watch the dots now while there moving. Do they fluctuate they should be smoothe. do this on both decks to find out which one is fluctuating.
