Help with TV HINARI CT20R

[vladinik]

Hi, TV HINARI CT20R : no sound, no OSD, no buttons, grey picture with moving white lines.
Inside:
MN15245KWC, AN5633, AN5601Ê, TDA2549, TDA8192, TDA1904
tuner-ENV-57843F2
memory - MN1220

I changed some condensers and resistors but no effect. Can anyone help me from where to begin the repair?

Thank you!

could be any of comp mentioned- generally r/p cheapest 1st- really have to know what each does- not guess or shotgun approach!!. suggestion- get a book on tv repair- learn- if succesful get circuit diagram of your set- the best approach is to take the tv to an authorised repairer!.
