Hi I have a Philips 40PFL3705D/F7 LCD TV. The picture shuts down after a while. Could be 3 weeks, 3 days or 3 hours of watching TV. Still have sound.


Maybe a thermal problem or there is something apart loose even use cold spray, manipulated by slight shaking or tapping components.

When do i use the sp/ep button? What is the difference?


In a VCR SP which stands for standard play on an E180 tape will last for 3 hours. So you can record 3 hours on it and much longer in EP however the quality of the picture will be less.
However I suspect that you could mean a DVD recorder. In which case a 4.7GB disc will last for 120 minutes on SP and 240 minutes on EP. Again there will be a loss of picture quality on the longer setting, but most people can cope with that.

I have sound but no picture, over the last month it has been taking an hour to get sound and picture from switch on, but today it is just sound after about 2 hours. 15PF4121/05


Similar problem in my Philips. No picture, just green led flashing in front panel. Reason was dried up capacitors in power supply card. Came on by renewing c223 and c228.

Is my picture tube going?


Most proj TV's of that type have 3 Picture tubes Red, Green and Blue. It's not likely that all 3 went bad at the same time in the same manner. So I believe you have a circuit problem, probably in the power supply stages, possibly a bad solder joint.

Hope that helps...

Picture getting darker


The tv has a room light sensor,
shine a bright light at it , does picture get brighter?
other wise when it is cool open the bulb door , is it coated or blackened, Don't touch bulb at all.

and a heavy covering of dust on internal mirrors will cause the same effect.
you will need help to clean it.

The looks of the bulb are no indication that it's okay. How many hours of operation do you have on that bulb? The bulbs are average rated for 5000 hours, but its been my experience that they usually last on average 3000 hours. Try replacing the bulb and then check and rest the buld hours counter.. Best place I've found for purchasing the bulbs is DLP lampsource. They'll sell you just the bulb without the housing at a dramatic savings. http://www.dlplampsource.com/
To display the lamp time press [ 2 ] nine times.
to reset press [ 3, mute, enter.] Or with the set in standby press [ display, 5, vol up, power ]
then press [ jump 3.]
Hope this helps!
