Who made me, the band and model number are worn off

[reble]

I have a portable dvd player that I got at a yard sale for $5.00 with no charger or cables. I did managed to get it charged up. The video play's real good but it has a sound problem. I get sound at the audio/video line out but no sound from the internal speakers or the headphones. I am trying to figure out who makes it so I can get a schematic diagram, then I can fix the sound. All labels with the name and model number are worn off. Please look at this Dropbox jpg pictures https://www.dropbox.com/s/hiw8779bhruf706/portable%20dvd%20player1.jpg and https://www.dropbox.com/s/cuapunix9ty4bvy/portable%20dvd%20player2.jpg Does anyone know who made this dvd player?

It looks a lot like a Curtis. Not exactly like the DVD7026A that I own, but the design is very similar.
