HI, Probable power supply board is faulty. Some times in power surge the mov (high voltage protection device ) will get short and blew fuse to protect further damages. Chekc is the mov in the input stage is short or not . MOV www.electro-medical.blogspot.com

The proper way to do this would be to use the audio output from the TV, either analogue left and right or the optical port, and send it into an dedicated amplifier or AV receiver. You can then use the amplifier or receiver to power the external speakers. If you are using a dedicated amplifier with no volume control you will want to change the audio output setting on the TV to "variable out" as oppose to its current "fixed out"settings. You can find this in the TV menu, usually under the audio settings. This will allow you to use the current TV remote to adjust the audio volume coming out of the external speakers.

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

The LCD sets use backlights and also a pair (some models combine both into one unit) of inverters- one drives left side and the other right side.You could have a bad inverter (some versions call it T-con) or even a bad display panel(main screen unit).In most cases this is not a do it yourself repair.

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. So it is not possible to show you exactly how T con board looks. Normally in all lcd tvs the tcon board is place on the bottom or top middile position. Which will be cover with metal cover or aluminium foil. Here I have added a link which will lead you to the picture of T con board for toshiba.( Not exact one) T con http://electro-medical.blogspot.in/

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.

Is it possible to see a picture of the fault? Do the lines go away after a while?

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.
