How to enter service mode, please ?
Medion CTV2118 service mode
-
-
Is it really a Medion?
I just know CTV2118 Roadstar or Telstar made by TCL china (chassis FS181CH--M17)
In this case the servicemode is invoked this way:
Press "display" on the remote and at the same time the Volume - on the frontpanel for about 7,8 sec. -
It is Medion.
There is nothing written on the chassis, it has VCT3831A.
Can not open service mode by this way.
Thank you anyway. -
Try this:
Press MENU button of remote handset to display the menu,
then press RECALL button 5 times to enter factory service
menu. -
Thank you but it is not.

I´m shure it is a chinese brand...either konka (as Gabrijel suggested) or TCL.
Vedran, which type of remote...is it original?.
Give the most important ics or a pic of the board to idéntify the chassis. -
I agree that's china. The remote is original.
Sound - Tda7057aq
Vertical - tda8172
main - VCT3831AThe remote has 3 hidden buttons. One is Display ( again), second one is woofer on-off ( TV does not have it ), the third one is nothing ( or it is !?)

for Merckx,
Menu and recall 5 times does not works -
its so difficult b´cause we dont know the Xakt TLC chassis and even subtypes like M35 and M35b have completelly different ways to invoke the servmode.

edit: pardon... i meant...do you have a "reveal" and a "caps" knob
-
