SOURCE: crackling noise from tv

That crackling noise has nothing to do with the television and everything to do with your antenna. It is merely signal breakdown, when you get signal interference with analogue tv you get snow, with digital you get little squares on the screen and/or sound breaking and cutting in and out, get a licensed antenna repairer to come out check your signal strength as you may need a booster or your antenna could just be a few degrees off....

Each time our TV starts the snapping sound we reboot the cable box. Problem solved.

First, HORIZONTAL CENTER.
1) Press MENU.
2) Scroll to SETTINGS.
3) Scroll to SCREEN.
4) Go to HORIZONTAL CENTER. Move the picture to the right. Hopefully, the line will go away. Otherwise, there is a problem with the pixels or the signal processor. Call 1-800-222-SONY. Or, http://eservice.sony.com. Have a high-limit credit card handy for out of warranty repairs. Sorry about that.

SOURCE: standby light blinks 13 times

Hi,
13 blinks is backlight error.. can be 1 of 2 things, 1st bad inverter board (on left side panel looking from back) it has several plug ins to the panel as it supplies voltage to the backlights.2nd could be panel itself as backlights are built into it they can't be replaced. Inverter is probably around $200 +labor, panel= buy new tv... they are outrageously expensive. Good luck!

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.

40 inch sony bravia making buzzing noises....any suggestions


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!

Sony XBR 40" tube tv.


Failure of the vertical deflection module/circuit. The tv will have to be opened, the vertical deflection circuit found and replaced.
Definitely a job for a pro - the circuit is going to be extremely difficult to extract. The repair will cost you about $200: $20 for a new circuit and $90 per hour for the 2 hour job.

TV cooling fan repairs


If the cooling fan vent has a removable panel then you should be able to access the fan through it. A silicone based type grease should be used directly on the fan shaft after cleaning...do not use a liquid or spray lubricant. The fan could easily displace the oil inside the TV chassis onto parts of the optics engine and do some damage or otherwise affect the picture quality.

Vertical line on teh left side of the screen


It definately looks like a mechanical defect with the screen. If you see the line when the set is shut off this means that the screen may have a crack in it, or there is a defect in the substrate.

This type of fault is fixed by replacing the screen assembly. The cost of this would not be worth it.
