Question about Sony Bravia KDL-46V4100 46 in. LCD HDTV

1 Answer

TV goes to blank screen standby after one second of normal functioning green power light on. When in standby state, the TV is blank like it's off and the red standby light blinks FOUR times.

When I plug the TV in, and before I turn it on, a single loud click sound comes from the bottom left of the TV. About 10 seconds later I hear a softer click sound come from the TV like the sound I would get when I turned the TV off when it was working properly. These sounds do not occur if I plug the TV out and then back in with a minute or so. The TV also does not power up and give me a normal picture for a second either when I plug the TV out and then back in within a minute it goes straight to standby.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

SOURCE: When TV is turned on,

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

SOURCE: red light flashes 8 times

I went to servicemanuals.net and downloaded the complete service manual for this TV and found that 8 blinks means you need to check out the Panasonic-txnss1rltu-ss-board which I have had to replace once before on this set. I have found further that this item is prone to short life as a result of inadequate ventilation problems. Anyway, the part I need was easy enough to find in the service manual and ShopJimmy has it for about $43. So my problem is solved now.

My tv made a loud noise like a vacuum them a high pitch noise and now it wont turn on unless I keep flicking the surge protector on and off.It wont even work when plugged directly into the outlet.


Power supply...The vacuum sound you heard was a capacitor failing. A capacitor stores energy for later use. For example, you turn on your TV, seconds later you hear a "Woosh" and the picture comes up. This is your tv's capacitor discharging. It's a simple fix if you know electronics though I wouldnt recommend repairing this yourself. There are several capacitors inside your TV. Though not fatal, they can give you a jolt. Call a repair man. I hope this helps : )

Tv won't turn on. blinking red light in lower left corner


unplug the television...wait 10 seconds and then plug back in....if you listen carefully after 5-10 seconds you will hear a click sound (the same sound that you hear when you turn on or off) ...once you have heard it, turn the TV on again using the remote. Do not turn on until you hear the click. If this does not work, try again but turn the TV on again before you hear the click. I dont know why it happens but it is as if the TV gets confused as to whether its supposed to be on or off. Most of the time, the solution is to turn it on after the click so I would always try that first.

Buzzing


If it is a buzzing noise, it is the Ballast for the lamp.
If it is more of a grinding sound, it is the Color Wheel motor.
Does it go away when you turn off the tv? If so, does it stop abruptly or does the sound tend to get softer (winding down noise)
If the noise stops abruptly it is probably the Ballast.
If the noise takes several seconds and seems to get softer until it stops about 30 sec later then it is the color wheel motor.
