Sony bravia kdl-46z4100 is 18 months old. TV speakers quit working. can they be replaced easily, or does a repairman have to be called.

If your TV is a month old call sony and get the TV serviced or exchanged. You are covered under warranty.

I would Google the model number carefully for "problems" "no sound" and usually this set will display some kind of error code===it may even have a hard reset to try===service manuals are available on the net/web to allow you to see how the sound circuit is set up etc.

unfortunatly, horizontal lines on an lcd tv, almost always mean a bad lcd panel. if it is out of warranty, it will be really cost prohibitive to replace the panel. if the set is only a year old or so call sony customer support and ask for a concession for the part.

I do not think that cause by power surge, and it is on manufactory warranty, you better to call Sony.

I have the same tv with the same problem. My tv is about 3 1/2 years old. I took it to the shop yesterday and today they told me that I had a bad lcd panel and a bad FL1 circuit board. They also told me it was going to be $3800.00 dollars to fix. I am now on my way to buy another tv, needless to say it will not be a Sony. Sony knows about this problem and refuse to do anything about it. Good luck.

Before calling a repairman, check the menu, if you see the problem on the menu then the set needs servicing, if not try one of the other inputs to make sure it is not the tv source that is causing your problem.

I don't want to go into details for you to fix it because if it is only 4 months old, you need to call for service. These tv's are all board replacement and are expensive to fix even on your own. Since it is in warranty defiantly get a sony authorized repair service to repair the set, the owner’s manual will have sony's phone number in it call them to get a service scheduled.

Sony also has an on-line tool to find a service center here
