In this model the horizontal drive coil vibrates and makes a high pitch squeal. Most times it is intermitent. Touching on the coil with something (non electrical, like wood) will make it stop or change it's pitch. The fix my shop uses: It's not to technical, but, we put fingernail polish around the coil. It's a remedy I've used for decades and has always worked. Some shops use a hot glue gun. With the back open you can hear the coil to locate it. When fixing the problem have the set unplugged. When a technician is working on a television while it's plugged in. He uses only one hand and stays away from the high voltage.

Toshiba HD ready TV ct 90158 makes high pitched sound


A high pitch sound can be a capacitor losing power it would sound a bit like a fire work. most have back up on the board but it put more pressure on them the more times you use the tv. would check them and replace. all of them can be 5 in a row in some models.

High pitch sound and fuzzy


The high pitched sound, probably not, unless you open this TV set and find out what is making the noise and replace the part. Most likely a coil or transformer is vibrating so fast that the frequency is very high. On the focus, possibly can be adjusted. Now when you take off the back of this TV set, i must warn you, follow my instructions to the letter as there is enough High Voltage in this set to make a grown man cry! After you take out all of the screws off the rear cover,carefully lift up the cover straight up. Oh by the way the TV should be face down. Opps! Not stand back up the TV set and there will be a Grey or black block like looking thing with a large red wire going to the top of the picture tube. on this block you will find two controls, one will say screen, and the other will say focus. DO NOT ADJUST ANYTHING ELSE WHEN YOU ARE IN THIS TV SET!!! No slowly rock the focus control back and forth till you get the sharpest picture. Put back on the back cover and enjoy!!! Good Luck
