50% trouble of tv is lose connection,first thing you will do is to re solder your tv. must specially the vertical section and the jungle

try turning the channel up or down with the tv remote to input 1 or 2 depending on which one is being used for the dvd player. tv should use input 1. dvd should be on input 2.
when turning the channel set it to show the dvd screen, then go up 1. if it doesn't show, return and go down 1.

check the RGB supply it is 180volts or the capacitor value 10/250volts (4.7/250v, 2.2/250v)

adjust first the screen. it is a knob at the back of plyback.(lower knob),if the has vertical line ,then the section had a problem.try to resolder the vertical IC or else change the IC.

I HAVE A NICE PICTURE BUT NO SOUND

i have a prima ttv2131 which locked as above and holding down the display button for five seconds unlocked it (as well as locks it)

sell it and buy real tv
