Does this TV use pwm dimming?

I'm not sure what type of dimming it has, but it definitely seems to be changing the brightness level on it's own, for some reason. I'd like to disable this feature, if I could figure out how. I turned off "Dynamic contrast" and "Dynamic backlight", but this didn't help.

My lamp does not have a dimming switch. But it is definitely an awesome lamp that stays on 24-7 in my home. I have one in every room.

Yes it does. However, in a dark room, the automatic controls seem to make the picture a little dimmer than I would like.

I doubt so. The unit is pretty much identical to any AC-DC converter you might find for any other electronic device, and they are built to expect a constant supply of power. The input specs on the unit also indicate it's input range would not accomidate a dimmer from what I can see.Your best bet from what I can see would be to purchase one of the PWM dimmer packages available if you would like to dim the lights off of this unit.

I don't know but the screen started going dark recently and there seemed to be no way to fix it (we tried the Phillips' website and they directed us to a sketchy TV repair business). The warranty had expired. Finally gave up a replaced it with Samsung.

No, but there is a package that includes a dial dimmer that will allow you to have that functionality.

This model tv has a built in sensor. The color is great in ambiant light or darker settings. I love the tv and have been using it for three months. Great buy!

Yes it does. The remote allows for easy switching between sources and also lets you fine tune the picture. I use that to dim the picture during hockey games (white ice surface is just too bright).

I believe what you are referring to is local dimming. Parts on the screen that have content are lit up and parts without content are dimmed down or even turned off. I've noticed that when turning on the TV the bottom left corner is brighter than others which may appear like bleeding but I'm guessing it's related to local dimming. I wouldn't worry about it. I watched dark movie scenes and I don't notice it, the picture is perfect.

Yes, I'm using it with the PWM that came with the LED strip I bought and haven't had any problems with it. I use it several hours every day usually on the lowest pre-set for dim as the room light for watching TV, bit also use it on full brightness. Never had any problems.

Yes it dims from full high or full low, you can ajust the light with the remote or the panel .You must use dimmable LEDs with this unit it works great.

Yes. It has a sleep timer, plus 5 other timers to turn the TV on and off automatically. Mine is on a satellite system, so I'm not using the built-in menu but this is a VERY fully-featured TV, and very attractive too.

I didn't understand that either. I hear you can adjust it if you put it into retail mode, but I haven't bothered to do so. Increasing the brightness any takes more energy and shortens the life of the TV anyway.

There is no dimming on this radio at all. It is surprisingly not as bad as some L.E.D. units I have had in the past though.

Sure is! The different modes are activated based on the angle you're holding it at when it's turned on. Straight up turns on the auto dimming feature.

No. It has a dimmer knob on the lamp. One if the features I like about this lamp! It dims!!!!
