Sorry for delay, you should replace the two D1138 even if they test aparently good, also when work on ms8 26 pay attention when you are on vertical deflection area because it will be all the way cooked and all traces so fragile

I have to repaint two Yellowed Capcon impress cabinets, just looking for repro sides art.

Use metal blue ones, those are just better than carbon resistors.

While 1454qm and 14m2 are very similar they have a different power board, by the way, the good news is that I have 1450 with a burn in on screen, so I can dusmantle it and supply a power supply, already serviced with best lytics caps (nichicom ucy an uhe series only) fully tested and...

Ok test all the polyester film caps on h stage there is one wich can cause this if just go out of is spec more than the 5℅ it's rate, also investigate into your psu board for components leaking

Pvm 20m2, 20m4 2054 1454 1450, are all veriy reliable BUT, could happen that some psu ics fail alongside with the HOT and one of the two v. Transistor. More common is the 5v regulator wich release the monitor just dead with tally light on, another issue is the 200v line just near the...

I have lots of those PVMs, beleave me your flyback is ok!

And yes you should but I din't , I have covered them with an alloy foil then removed the ic, basically I have cooked them :) this worked anyway. Removing the lytics caps and replace them is also a good idea since in that area they often fail due to heat gen between the v. Blanking ic...

If you have already checked the two dumper diodes then there is also an ic wich provide E/W control , if my memory help, it is the ic 509 , should be a LM3580, in the past I have repaired a 2054 with weirdo pincushion issues and just was this ic! You should use a hot air station to rework...

Hi, do you still have the 2730qm? I' m looking for parts, if you want you can sale me some parts.

You have to replace c433, r433, r436, q401, q402 and c437, plus you have to check for broken or cold solder joints just under q402 and q401 this is an hot area look also for broken traces. Q401 and q402 are both D1138 transistors, r433 2.2k 1/4w, r436 15k 1/4w c433 10uf 50v .

Have you already checked the others psu rails, on pvm 20m2 m4 there is a 5v ic regulator wich often fail alongside with the hot and another ipower regulatot ic

I got a Capcom imoress in very good condition but without control panel and another one wich need the cp to be replaced too. Thanks in advance!

I need two capcom impress repro control panels.

Before replace any part you should first study the circuit of the switching psu section then test the parts out of the circuit and if truly out of spec, replace . I will try to inspect into that board to give you some more infos and test points to check.
