The high-pitched squeal is from the power supply, usually because of failure of the horizontal output transistor, flyback transformer, or both. Without a specific model I can't give more definite information about part numbers or likely costs. But repairs of this type usually have parts costs in the 10 to 75 dollar range (depending on just which parts are bad, and where replacements come from) plus whatever labor costs the repairer charges.

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.

It's not the picture tube(especially if image was good b4 it went dead). The high pitch noise is the power supply whinning because it's shorted or overloaded. I just fixed one of these sets - replaced the horiz. o/p transistor and flyback estimate around $120.00-$160.00

Same problem, high pitched noise over regular sound and no pictur


No guarantees with this diagnosis. But it sounds like an HT ( high tension) leak This is often caused by the lead becoming partly unplugged ( being bumped or moved) and because of dust buildup it arcs making a high pitched hissing whistle.Ther lamp may also have been affected by the HT leak. The safest option for you is to call a service technician to it, as opening it up could cosntitute a a danger to the unskilled.

No Picture


Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.
