Then some hi res images too a good one for @Pook to make??

AI says MJD117T4G

Some on eBay nearly 3 quid each! Might just pinch one from a faulty board for now. can you remember the smd part Id? thanks Ronnie

your proberly need a new working cpu card, these get damaged by the battery which leaks and vents, if it has really been left for a long time this can affect the impact motherboard causing track and component damage as well.

there are some surface mount transistors which have the same ratings, and i did have a plan to fit these to a small pcb with legs so would be a drop in replacement. but that never happened for reasons most will know

my research has found there is nothing that is a simple 'drop in replacement' everything needs some alteration. you could use a tip116, but the legs don't fit in the holes and have a different pinout, as you have found tipp116 went obsolete some years ago.

Thanks looks like these are obsolete if there is nothing compatible might need to gamble on eBay

no, that's just a normal transistor, not a Darlington transistor

Anyone know a suitable replacement for a tipp116 as found in mps lamp drives would a 2N3904 work? or any other that would? Thanks Ronnie

Anyone here repair or test JPM impact 1 boards for a 1995 Cluedo quiz machine.. machine won’t start up.. thank you.

Can you dump the ROMs for this? Would be nice to see this emulated. 🙂

12 volt T10 Wedge bulb, 1.2 or 2 Watt, I imagine if most of yours are dimmer they are 1.2 watt and you may have a few rogue 2 watt fitted. The 1.2 watt are better anyway as they are kinder on the artwork, plastics and electronics as they generate less heat / load. There could also be an issue with lamp drivers etc but sort the lamps out first.

Happy days, what a nice clean board 👍

What a result Ronnie, great machine 👌

Thanks guys I’m loving it! Managed to crack one its own mpu looks like I just caught the battery in time! Wet patch under the crusty battery, Otherwise the board is very clean

Very nice. Love it

Beautiful ronnie .nice little run on 10p wins there lol!

Is it working now?

Well.. reseated a lot of connectors, and everything seems to be running in door open mode. Which..tbh.. is ok. I'm not going to fill this machine with £150 of loose change I don't have. Bulbs!!. Most are dim, some are burnt out. What is the bulb number to replace them with. It's a wedge style bulb. Thanks. Statto

Will try and do it again, if not will upload to youtube

Same here too ronnie cant view it

Not sure what happened here! Worked on my phone, will try again edit, working for me

IMG_6526.mov She lives! Fitted my working spare board, still no boot! Cracked open the game card and re seated the roms and bingo she sprang to life! So its own board works on the bench but I will need to open it up and check it over for battery damage and replace the caps etc but I’m well delighted 🤩 Short video with 20 credits

I know think it was DPD he used, he had another base but has since dumped it! I think it would be too much hassle for you nick but thanks for offering it
