A complete manual would be nice if anyone has one?

Found it on one of my other laptops. Need to organize these I have so many I lose track... if I have it happy to share.

Need help, does anyone know where to find a d9400 service manual. If so please post or email me [email protected]. Working on one that blew the hot and the b+ starts out at zero and slowly rises to 180.

Looking for a board for parts. In particular the 2 stand up IC’s. Located in Ontario Canada Thanks in advance Rick [email protected]

Does anyone have a schematic for this monitor? It is not 29ES1. I am trying to confirm the Part# for the mode Ic 801 think it is h06co1565rt?? Thanks Rick

Yes it is The 2SD1879. Definitely not the the same as an NT2515. Some similarities to a 2700 full family. It had a dead primary supply, then bad smps supply, then not oscillation so no high voltage. Had a to change a couple sweep caps and the Hot.

Nameplate shown.

Neotec seems to be out of business?

I think you meant 2SD1879. Please note I made a typo above. Eats them to.

I will have to try to find that number. Here is the license/model label.

In some cases I think it was the board supplier and assembler used? Thanks Rick Nieman Nieman Video Displaus

No I have one of each in front of me. There are a few differences. For example the 2525c had the signal input on the main board the 2500 has it on the neck board. Small differences in the power supply as well as others. Every time I think I have seen them all, something else pops up.

Does any one have a Neotec NT2500 and confirm the correct HOT part #. i believe the following is correct for others: Nt2700 Full family- BU2532AL NT2701 Lin Shi - 2sc4542 NT 2501 - 2SD187 NT 2502 -2sC4542 Nt 35C - 2sc4542 NT25C - 2SD1879 NT25E- 2SC1879 or 2SC2542 Not sure about the NT. 2500 I...

Agreed the LM1203 or shorted green transistor. start with the transistor.

Neotec Hots: Neotec 2701Family version uses Bu2532 Neotec 2701 Lin Shin, NT2501 NT 35C usues 2SC4542 NT2500 and 2515 usues 2SD1879 NT25E usues 2SD1879 The 2542 crosses with NTE 2354 All use 2SK1507 for the regulator except NT35 usues 2SK1358 this s based on what I have seen in the nauals, canno...

So there are a few versios of of the 2701, All I believe are mid res. The tube and yoke I have here for service is an RCA with a yoke with a horizontal inductance of .24 mh… this should be VGA? What tube do you have. Multitude of HOT's 2SD4769, BU4530, 2SD1879, @SC4542 as per various...

Sync issue First it is a horizontal sync issue. Diagonal meas the horizontal hold needs to be adjusted. Basically if the monitor is scanning faster than the signal input tears to the right, slower to the jeft. Vertical is a roll. I can send you a G07 manual via email.

Dead Neotec 2701 I know your post is old, but any chance you found the issue? if yes and you remember please send me an email [email protected] Thanks

The Schematic was here https://www.arcade-museum.com/manuals-monitors/Neotec%20NT2500_NT-2501.pdf

Yes I tried all the same sites still looking Yes I Tried all the same sites, not even sure now where I found a schematic. I would attach it but exceeds the size limit. Guess I will need to keep looking. Already solved the board problem, but I try to save documentation.
