Our DVD player wasn't opening so we took off the back of the TV to try and fix it. We fixed it, but when we reconnected the wires, we now get sound but no picture at all, just a blank screen. Are there any particular wires that control the ability to produce the picture that we should check? We don't have any technical knowledge about how a tv works.

Re: Sound but no picture
Is hard to tell what might be happening but the set has wires coming from the chassis to the crt board,backtrack your steps and check the conectors,ussually they can only fit one way and can not be forced in,make sure they have not been switched and stay away from the thick red lead coming from the output transformer to the back of the picture tube,it has high voltage and it can hurt a grown up man easily,the crt board in the neck of the picture tube nneds to be pushed in all the way,just checked that is in and if you have to remove it make sure you pull straight out and do not twist it because one of the pins in the crt might break,if you took it out before just check that one of the pins is not bent.Let Us know if you need more information.

just took mine apart tonight. your opener on the DVD tray requires a small rubber band. It looks like my rubber band is barely working but doors still open.
IF ANYONE HAS A "NO DISC" MESSAGE, TRY CLEANING THE LASER. The laser is right past the bottom spool, dead in the center. Might require a long q-tip. The top spool does not turn on it's own but requires the bottom spool to turn.
IF YOU ARE GOING TO TAKE IT APART: 1.) have some fingernail polish ready to mark wires. Use many diferent colors. 2.) There are probably at least 5 clips to disconnect. I took out around 25 screws to get to the least ammount of work for the DVD player. It really is burried in there. 3.) The central board near the end of the tube is holding residual power. Gives a nice little shock -- even when the tv has been unplugged for a while. 4.) remember to ground yourself out and other precautions. Again: The DVD player is really down deep and requires many wires to be removed to get to it.
I ended up taking off the top board and prying it so that I did not have to cut the tube power wires. The power wires to the tube must be soldered back together. :-)
*Have multiple screw drivers ready. ** Have extensions for your screwdrivers.
I got this tv/dvr used because the last owner couldn't get it working. Looks like a pretty good picture. Even though philips has a DVD at target for 30$, the integration is well worth fixing/replacing. This 5 year old DVD is playing really well while the Philips often die in 6 months for our use.
if your are able to open and close the dvd and able to hear the tv clike it means you secondery power supply is working you have the +5 volt and some other votege i will look in the hv section and see if you have +120 v you may have hv short
It sounds like the audio cable from the DVD drive may be loose or damaged. Did you wall mount the TV and this is when the problem started or has it always been like this? If its under warranty, contact the helpline on 0871 2000 463, be warned, if its becuase the cable is damaged by a wall mounting screw, its clearly evident and they will charge for repair.
You have your DVD connected to your VCR, which is then connected to your TV, right?
The problem is Macrovision. It's designed to prevent you from connecting your DVD player to your VCR, so that you can't make duplicates of copyrighted movies. It's a real pain in the neck.
Try turning the DVD player off - or better yet, unplugging its power cord (as some DVD players are always in a standby mode, even when turned off). If that fixes the problem, then you need to reconnect your DVD player directly to the TV, not wired through the VCR.
If your DVD player isn't wired through the VCR, are you using some kind of wire splitter (one cable branches into two) to connect both the DVD player and VCR? That can also cause this kind of interference, if both have power at the same time. There are video switches you can get to work around that. Here's one such switch (first I found for a decent price with a google search):
Hope that helps.
