Ok, first of all have a look at the 'road trip' done for that cab' here :
https://www.dragonslairfans.com/phpBB2/viewtopic.php?t=112Now, let's start from this point :
The monitor doesn't work anymore
Not a big problem, the tube had a lot of burns... for that cab, I want a perfect picture , so it's a good reason to remove it :
That monitor is easy to remove : only few screws...
By the way, I'm checking his serial number : 1691
Very low number, I like that
The SN is also inside the cab' :
Hey, a fly... escaped from the Galaxian armada
:

:
Here you can see all the screen burns
:
The monitor is ready to be removed... from the monitor support :
...another view before 'the operation'
:
By the way, it's an old Wells-Gardner K4500 19" :
I remove the chassis :
...an important sticker...
...to keep !
I
The tube is removed... :
...and the monitor support is ready for...
...this TV
:
I got it for something like 60€, second hand of course
Cheapest than a brand new monitor :idea:
Let's disassemble it :
...carefull...
Et voilà : all I need is here :
I hope the tube fixations from that TV are the same than the monitor
Arg... no luck
It doesn' t match the existing holes...
Ok, let's make new holes :
... and this is it : the TV tube is now fixed
... and the PCB too :
Ok, the idea is to use the real miday's Galaxian pcb on the TV, with a true RGB signal. European TV allows that type of signal, with the RGB scart connector
So I'm quicly build a test cable :
ARGGGGGGGHHH, it doesn't work... but I'm not sure If it's a problem with my TV, or the cable, or the pcb... so, I'll use my Commodore Amiga monitor to test the PCB
Ok, I'm sure that the pcb is working :
closer...
Let's check my 'homemade' PCB -> SCART...
Still not ok :
What can It be
:
Well, I guess it's working with the Amiga monitor because it has a separate sycn signal : 1 wire for hor.sycnh and 1 wire for vert.sycn
The TV has one wire on the scart connector for the sycn, so I presume this is the problem
If it's the case, I need a LM1881n chip, in order to separate the sync. :
I've ordered it... I'm crossing the fingers
