Philips 42PF5521d/10 When I turn on the tv the volume automatically turns itself up to maximum. Pressing any buttons on the remote has no effect. When I press either the + or - volume buttons on the side of the set the volume does go down. But, as soon as I release the button the volume climbs back up to maximum again. Any ideas please?

i think that there is a shorted buttons or in normally close position, try to press each buttons slowly and you will feel something that is ticking if one of the buttons does not tick it is damage it is in normally close position that will be the cause of the problem. specially check the volume button.
I just had this problem with my 3 year old 32" Samsung LCD. The volume would go up and down by itself, normally just constantly going up even when it reached 100%. I thought it might have something to do with the volume buttons on the TV itself so seeing as it was out of warranty anyway I decided to unplug it and open it up. I gave it a good clean and I disconnected the cable for the panel of buttons on the LCD itself (volume, menu, channel etc) seeing as I never use them anyway. I then put everything else back together and tested. It seems to be working fine now. Previously (for the past 3 hours) ever time I turned it on the volume level would come on instantly and stay on until I turned the TV off. So I’m quietly confident the problem has been fixed. But I must admit it’s only been 10 minutes, so who knows, it might come back.
Question: Take the batteries out of both the remotes and then try to turn the TV on with it's On/off switch built into the TV. If it turns on and the volume stays the same, then it must be an issue with one of the remotes. If the tv turns on and the volume ramps up to max. Please check if volume knobs/buttons on the tv itself to see if they are sticking. If they aren't, there is something wrong with one of the boards in the tv of course. This sure should be something a Sony Service Shop can fix. I don't think it will be expensive. Maybe a $100 to $200 repair if they do the work. Blessings, A/V Media Guy
use your camera on your phone and point the remote at the camera lense, you will probably find the remote is lit up and the remote is the problem, button on the remote is stuck and sending signal to the tv all the time until the batteries go flat. if its not that then the tv main av controller board has a fault. there area on the board for remote signal control.
This sounds like there is a stuck button. With the TV off, try each of the panel buttons. You should feel the button engage. If not, that is the faulty one that should be replaced. Also, check to be sure that the plastic covering that extends to the actual switch inside the set is not broken causing a switch to be stuck on.
Keep us posted.
