I once had a problem with a Phillips tv.It was less than one year old and one day ,all of a suddenm a black screen came up.I elarned it was called the "black screen of death" and that other people had gone through the same thing.Someone online had actually written to Phillips and they had gotten a new TV form them,so I tried the same thing and amazingly,Phillips gave us a new TV and came and took the old one.The enw worked fine. So you may have a lemon on your hands.Unfortunately, I do not have the letter I sent to them but the replacement they sent me was part of their "Rapid Replacement" program.This wa sin 2008 so I'm not sure if they still ahve it but it may be worth a try.

No picture for phillips 40 pfl3705d


There is no raster to your TV I assumes. If the LED drive inverter board has damaged, there will be no back light, and so no picture. If sound is OK, suspect the inverter board. Check this for more details.

I have a memorex LCD HDTV 3yrs old, now the set has perfect sound but no picture, just a black screen,


Your LCD lamp may have burnt out or the component usually a driver transistor that drives the lamp to glow may have been defective. Some of LCD have fuses on this section that automatically opens when there was a problem. A qualified electronic service technician could figure out your problem right away if you don't have any experience in electronics troubleshooting.

Sony Bravia with Phillps dvd player


The DVD player may have multiple output formats that can be displayed. Sounds like you have the composite output selected when you have the component output selected on the DVD player. Check the menu options on the DVD player and confirm they match the way you have the player connected
