The vertical output circuit has a failure. Very likely the vertical output i.c. and perhaps some small related components. These parts are soldered in place on the main board. If you are technically inclined and able to solder you should, with a schematic & digital multimeter, be able to fix it. Otherwise locate a competent technician or consider a new unit. I wish I always had good news and a quick fix, but my car mechanic usually can't do that for me enither. Good luck.

Looking for an operating manual for DWX 2880gb Daewoo TV. My mum played with the remote and scrunched the picture down to a band across the middle of the TV and we can't get it reset to a normal picture.


You can do an online search for this. Put
"DWX 2880gb Daewoo" in the search box. This web address should get you what you need.

I have sound but no picture--just a colored line down one side and the text for the main screen scrunched up into a corner


Sounds like the deflection circuitry has failed. You will need to take the TV to a repair shop (or just buy a new TV). There are "no user serviceable parts inside" so don't try to repair it yourself.

this is called a "collapsed" picture. it is normally a simple repair for a tv technician. simple for them but almost impossible for the average consumer. if the set is fairly new and not under warranty it might be worth your effort to take it to a tv repair place and get an estimate on the repair cost and go from there. if it is an old set it is time for a new one.

Check first for bad solder on the vertical IC, Im not sure for your set as I do not have the service manual, but it may be location IC301. If after resoldering it does not fix it you may have to replace it and you should replace the electrolytic capacitors in the vertical section. Hope this helps. Don

Picture problem


Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.
