Loud buzzing sound on Sanyo AVM 1909

If it is a high pitched whine or buzz it is likely a transformer vibrating so hard it is making the noise.

There are ways to try to deal with this issue but the set has to be opened and probed to locate where it is coming from--


for example with back off and set on a plastic rod can be used to touch areas and exert slight pressure until the sound changes or goes away--then either replace the part or I have used hot glue etc to stop it.

You first have to locate the source of the issue:

find where it is coming from.

jupitor3433, Unit has problem with internal ac to dc power supply that a technician will need to investigate and repair. 12fixlouie

now those tv cann't use without a digital converter box .call your cable provider for assistance

loud buzz is the color engine, turning the color wheel. Find instructions on how to take it out and clean it and that should fix that problem.

It sounds like a bad internal connection or a component failing. If the picture still is very good take it to a known good repair shop.

Have the speakers ever been played loudly? They may have been pushed passed their capacity, in which case, it may be time for a new tv.

Defective audio preamp IC. To a shop it must go, unless you fancy yourself a "techie"...accordianman

Sanyo Model AVM-1304 This TV has a loud mechanical "chatter" (or clicking)that appears to be coming from RL001 on the motherboard as soon as ther TV is turned on. I can feel the mechanical vibration on the component. The Picture and sound are very good. The chassis is G6Y-13040. Any ideas? This TV has a loud mechanical "chatter" (or clicking)that appears to be coming from RL001 on the motherboard as soon as ther TV is turned on replace relay as it is easily available or make it direct. .

it looks like a capacitor problem in power supply circuit. the humming and waving of the picture is caused by a faulty filter capacitor in the power supply circuit. have it check and replaced if found faulty. good luck!
