Top 20 Sony Bravia KDL-46V4100 46 in. LCD HDTV Questions & Answers

Hi there,
If you haven't done so already, check that the cable between your tv and digital cable box(probably HDMI) is secure at both ends. If it is, try a different cable and/or different port on your tv if you have more than one. If the issue is still there after you've tried these options it's most likely an issue with either the digital box or tv. I would contact manufacturer at this stage for advise and possible replacement of tv or box if they are under warranty.
Hope this helps.

I would think its a T-con bard fault its the main board for the screen over time they ware out from heat. this control the picture for the screen. they can go in many ways, black screen mixed or shadows even star screen and scramble type screen. and white lines and even half working only.

Those 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://electro-medical.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

You used to be able to stream Netflix on this model with the Bravia Internet Video feature. (BIV) Unfortunately this feature is no longer supported. In order to get your Netflix now, you will need a Roku box or a Netflix thumb drive (fire stick). I hope this helps.

Hi, Yor tv have problem with T con board. T con board is one which drives the pixels of the LCD panel. If any of the driver satge in the T con board is faulty then this problem can occur. Some times bad contacts on the connections of the t con board can cause same problem. Remove the tv and find out the t con bard. Remove the connections to it and the reconnect the connections. Then check, if the problem remains the same then the tv need a new T con board. You have didn't mentaioned any model number of your tv.

Which will be cover with metal cover or aluminium foil.

Broda before we start, are you a technician? Because this has to do with real technical knowledge Henry

I checked on the schematic, there is a self diagnostic mode for the tv accessed with the remote control. If the TV does not turn on I would highly recommend finding a local reputable service facility as this might be completely a fault inside the TV. https://www.encompassparts.com/shop/model_research_docs/?file=/SON/sm/KDL46V4100.pdf Please check page 12 for self diagnostic procedure.

First you need a television with an internet connectoin. If there is an Netflix app installed , the app. can be started. If the set is a bit older and there is no Netflix app you can not use Netflix via the television. You can view Netflix with some brands mediaplayers.

The time controller ( t-con ) has a defect. There is a small IC called AS15-F which must be replaced. Check the red circle at the upper left corner.
