My Sony Bravia TV (model number KDL-46W905A) turns off randomly every few minutes. At first it seemed that it only happened when it was directly plugged into the wall, but not when it was plugged into an extension cord, but now it happens no matter what. It always turns back on after a couple of seconds, and is otherwise working perfectly, but something seems to be tripping and turning it off, with no apparent pattern. I am new to fixing stuff but really don’t want to have to throw away an otherwise perfectly good television that my landlord was going to throw out! Thanks to anyone who can offer any advice!
Hi @pbddn, When it switches off, does it go back into standby mode and you have to turn it on or does it restart by itself? If it goes back to standby and stays there until you turn it on again, then it sounds as if something is overheating and it is shutting down. If it restarts by itself it could be a loose connection (dry solder joint?) or a voltage problem perhaps Here’s the relevant troubleshooting flowchart from the service manual which may be a good place to start. (see p.26 also)
It needs a software updaye I has the same problem
