We have a Panasonic TV - Model TH-37PX60U (purchased 08/2006) that makes a "chirping" type noise periodically - sort of comes and goes. Any idea what this might be? Thanks, Mike G Pinellas Park,...


Sometimes that "chirping" is caused by loose windings on various transformers. You can usually isolate a particular transformer by pressing on it when it is "chirping" & it may stop "chirping" or the frequency my change. If that is the cause, you can A: replace the coil, B: replace the Printed Circuit Board, or C: Do nothing as it really isn't hurting anything but your nerves.

Panasonic NN-H264SF Microwave oven starts with a chirp


No I dont think so, check that the wheels on the rotating ring are not seized up and dragging. These will make a chirp type sound as it starts to rotate or even when it finally comes to rest.

Noise from hitachi 42PD5000


The noise is coming from one of the plasma driver boards. There are 2 inside the set. These are essentially power supplies for the plasma itself and contain many capacitors. The noise you hear is some oscillation inside a cap or two. This is an indication that one or more components have drifted from their rated value. While the set will continue to work for a while, that board should be replaced. If the board fails, 1/2 of the picture will be blank or the set will not start at all. Call around to get the cost of that board. Please note that continued use of the set WILL NOT cause any harm. This is an annoyance only at this point.

Television making chirping noise


Chirping or hissing from the TV is caused by a faulty CRT base socket in 95% of the cases. Replacing the base socket is an easy job, but care must be taken to get the same replacement base socket. You better desolder the existing base and take it to the shop to get one with the similar connections. Good luck.

No picture on screen, chirping noise every second from back


again a good set the deflection modules on these sets are pretty reasonable you need to have a tech swap it but i highly suggest that than a new one the chirping is the set trying to start up but going into shut down

No power just a chirping noise.


Chirping means the power supply is being loaded down by a short in most cases, likely a bad convergance IC

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.
