Buzzing noise...sounds like its coming from top right corner...standing in front of tv
Hello,
There are 2 small 1.5" fans that are located on the top right and left sides of the screen. These fans are of the non ball bearing type, so the bearings may be wearing out. You can either replace the fan or add a couple drops of oil to it. Remove the label on the back of the fan and put the oil there, it should quiet down. This will work for a while but eventually the fan will need to be replaced.
Good Luck!

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

Hi,
It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty
The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.
All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.
The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"
Thanks
SOURCE: buzzing/fizzing noise from back of sony flat screen tv
Below is an image of rear side of your TV, Sony KDL-40W5500
Top right corner is marked there and possible cause of noise seems back light inverter board, there are high voltage going to CCFL inside LCD panel and seems high voltage leakage causing that buzzing/ fuzzing noise.
Replace back light inverter board upon voltage leakage confirmation.
Thanks.
Testimonial: "Thank you very much for the very prompt reply. This seems a very likely cause. My TV is only a week old so I will contact the supplier. Thanks again."

Could be the decoder:
1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)
What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.
Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.
1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.
So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.
I sure this will help.
