Question about Sanyo DS25390 TV

Sanyo DS25390 Well it lasted a while but now it has a loud Buzz. We left it on over the weekend while away and came back on sunday to the loud buzzing. Everything works fine with the exception of a "wave" that goes up and down the screen slowly. I took the back cover off and there is a large square relay on the board that is vibrating. Is it the relay that is bad or what feeds the relay? anyone have any idea where i can get the parts once i know what it is? I can do basic soldering so if its the relay

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!

A loud buzzing is coming from the back of my sanyo ds 25390 tv. picture and regular sound is fine

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.

Sanyo tv ds25390 buzzing sound

I had the same problem with the same model.
The solution was to replace a capacitor, C622, which is located near
a small blue rectangular plastic component.
This component is a relay that is controlled by C622. I paid $2.39 for
the part, $8.99 for S&H for a total of $11.38. This fixed my problem!

Loud Buzz upon starting

sounds like just a vibration caused by cols hitting the frame perhaps, sometimes a pull from underneath the unit on the condenser coils will rectify the problem(id give a pretty quick tug, . unit could just be settling into the floor or the house settling around it, vibrations are definitely annoying but usually no need for alarm

Power cord pulled out

i have just pulled the back by removing 5 or 6 screws. you can see the circuit board, and the power cord is soldered directly into the board. two wires,one black and one white. near the left back corner--- from the back. you can re solder it.
