Poorly made transformers can cause odd noises if the circuit in which they are used continually tries to start but is shut down again immediately. I would suspect some component in the main power supply, quite possibly a failing electrolytic capacitor causing it to cycle.
You might check with Philips to see if they have a repair or replacement program for the supply. You will have to gain access to the guts; probably via a lower rear panel and I would allow the set to stay unplugged overnight as some parts remain alive and others can carry a charge for hours. Look for a board with larger-than-average components on it, particularly the mentioned transformers which are block-like objects and also the board will have larger cylindrical components on it as well. If will have one or more part numbers that a service center can use for reference.

Maytag electric dryer, lights flash, chirping


I had this happen with a maytag washing machine. The repair guy replaced a board and it worked fine. I'm afraid that's what happened here.

The convergence issue might not affect the TV to the point of not turning ON.
The chirping noise you hear, it means there is a short circuit in the circuitry, possible the HOT or power supply assembly.

You can disable the chirp confirmation by using the following procedure

1. Turn the ignition on
2. Turn the ignition off
3. Press the valet switch 5 times, wait for the Status Light to flash twice, the parking lights to flash twice and the horn to chirp twice.
4. Press the valet switch 4 times, the MARS unit will respond with 4 Status Light flashes and horn chirps
5. Press the transmitter START button, the MARS unit will respond with 3 Status Light flashes and horn chirps
6. Turn thr ignition on to exit program mode

My 97 jeep grand cherokee makes a chirping sound under front


The noise and the light may or may not be related. The noise may be the wear indicator on the brake pads touching the rotor (they are supposed to do that when brakes are worn) The abs light triggers off a wheel on the axle end. If you have a bad joint on the axle, it could be noisy and causing the wheel to not have the proper clearance to the abs sensor. You really need to take the wheel and brake assembly off and carefully inspect everything. Make sure all abs sensor wires are undamaged...it doesn't have to be at the same wheel that's chirping.

a shorted horizontal output transistor will make a funny squeek or chirp noise when turning on the tv. Usually mounts on a metal dissipator near the bulky plastic part with the red thick wire coming out of it.good luck!

PT-43LC14 No Picture, chirping sound when turned on


Most of the time, when there is a chirping comming from a TV set, there is a short somewhere inside the TV set. That chirping noise is the TV's power supply starting up and shutting down because of a heavy load on the power supply. These sets have no user replaceable parts inside them, so play it safe, and call out a pro to assist you in this repair. good Luck PS Please do not forget to rate this thread.

Flashin power light - wont come on


The "green light flashing to the chirping" circuit may be defective.

Not a basic diagnosis--service literature and/or knowledge of each green light circuit will be needed.Possible shop repair.
