Ok, first of all have a look at the 'road trip' done for that  cab' here : https://www.dragonslairfans.com/phpBB2/viewtopic.php?t=112

Now, 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  

nice stuff boss !!!!

busy as usual.... i hope it work ...

what the plan for the 2nd galaxian ?


just by curiosity, how much cost an old tv like that ?

Thanks ArcadeFever  

I'll probably sell the second one...

I paid approx 60€ for that TV... I can buy brand new one for approx 120€  

A good replacement for an old arcade monitor.

The picture quality on these TV tube  with an true RGB signal are the same, even better quality    
The advantages on true arcade monitor are all the pot' to set the image geometry and the mounting fixation... but on old TV, there are sometime the pot' too    

nice !!!!!

one more to go  

Arghhh.... ...the original Midway is now dead        I tried to repair it... but no luck... it's worst      

So I got a Galaxian PCB, modified for a Jamma use, but no luck for me... The 'fire' sound is not exaclty the same than the original one, so I'll emulate the PCB  

ARGHHHHHH.... no luck at all... A bad move.. I broke up the TV too                220V into the scart        the TV pcb is DEAD      

All the previous work done... for nothing  :x  :x  :x  :x  :x        

Well, so let's start with an other TV... I got this one for 80€, second hand of course :



It's a 19inch Trinitron Sony  

OK, same operation than the first TV : open it and see how to fit it in the Galax" cab'  



This TV has two pcb : The main one, and the Power supply pcb :



I put some fixations in order to fix the tube in the original Galax' monitor support :



Power on :



Ok, time to put all the thing in the cab... let's go back to the Nuno's Lair  



In the cab now :



The picture quality is amazing ...



Remember : True R G B signal with AdvanceMame dos via a scart on a trinitron tube : the colors are wonderfull, and the black is .. black  





Next step : the cpo...  

before starting to work on the control panel, I'll sand + paint the marquee bracket :



Finition with sandpaper :



First layer (primer, not the final color of course ;-) ) :

OK, the marquee suport is done... and dry :



The 'primer' layer is finished on the control panel, I'm applying now the first mate black paint on it :



Let's wait... fresh paint  

OK, now the final step : the coin door  

Here's the original coin door :





  very bad  

I'll paint all that stuff... and I'm luck, I've found the perfect color    :



Sanding the stuff...



...and painting, with ALWAYS a primer layer first...





... even this small item from the door  





...cleaning & rebuilding ...



...and here's the result  



I just need to found a midway coin door logo sticker... but for now...

PLAYING TIME      



     

NICE....

that cab look like new

so, you use a pc inside ?

Yeps, an old Pentium II 400Mhz with DOS Advance Mame ... it works like a charm
