The TV is in some kind of protection mode, the blinking LED show you an error code.
Try pressing 062596 and then press menu button (do these in quick motion, don't let them to time out while keying)...see what happens
Well I think that if you would have a service manual for this set that would help a lot, I can send it to anyone who wants it via email/gmail. Let me know if anyone want one.

I also heard that this problem appeared with some people because the of the burnt fuse in the TV. To fix that it has to be taken to the tech shop. mecry.gif

And yes I also heard about this issue many times, seems like this TV set is very popular with this kind of problem.

SOURCE: No picture on Philips LCD TV

One very common problem encountered on many Philips models, old and new, In some cases, the SSB board has to be replaced as the resistor on the PCB on the back of the CRT had to be fixed. In other cases the Y Sustain board had to be replaced. If the problem is not due to these two issues, then the capacitors will need to be replaced as they only have a fixed guaranteed life. Thus, it would be wise to take out an extended warranty on Philips due to this common repair issue which often occurs after the limited warranty has ended. Or you could just call your local repairman. There are lots of websites on how to fix it yourself on google. There could be many reasons. Hope this helps!

Phillips 47PFL422D/37 I've had the tv about 6 years with no trouble. But now the picture is to dark to watch it also pulses. I've tried to unplug it and plug it back in I get a picture for


First, average life on these sets is about 3 to 4 years at best and only boards are sold so even if you can pin point the board (no individual parts are sold) it is likely if will not get fixed and doing so is a bad investment as all the boards are now old.

My philips lcd tv has sound but no picture what is


change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.

37" Philips LCD sound but no picture


Check the inverter on the sides of the TV. This sounds like the inverter is going bad and that's the reason why you have sound but not picture.
