I have been tracking down the fade then blank screen for a week. Figured it out. Heater voltage drops to 2.5v Why? because the fuse tests good on continuity, but when I pulled it out, one of the sides started to spin and the inside was corroded. High resistance and low voltage was getting...

Thank you Gamefixer! I had a bad 620k ohm at R324 also. Fixed my blank screen. Thanks for posting so I could find the problem. (Original issue was I had neck glow and HV, but no pic, it was playing blind)

jumper There is also a jumper at R330 to R331 on the vertical board back side. I am not sure is I caused it to separate when I removed it or it was meant to be unattached.

I have a C551 cap in the kit that has no cap on the chassis. There is a space on the chassis on a very small side board. Do I put it in as an upgrade?

Here are two pics. What should B+ value be?

kit I got my stuff from Arcade Parts and Repairs. He has a ton of great stuff and kits. https://www.arcadepartsandrepair.com/

I don't see the LM1203 chip on the board.

No noise from flyback

Woke up to a dead Kortek monitor: KT-2001SF I did a recap kit and power cap and a HOT which measured bad in my opinion. Worked for 3 days and then graphical issue as seen in the attached pic. It is the chassis since I tried another pcb and a TPG and same picture ocurred. Any help or who can fix it?

I need K G1 G2 F1 and F2 for my Sencore

Thanks for the BK setting. But now I realize the unit is not working correctly. Do you have the settings for a Sencore CR70?

That helps but what about the settings?

I have a Sencore CR70 It does not list this tube. It is a med res in a Daytona USA that has a WG7500 25 inch chassis. Colors a badly washed out and I hope to clean tube color guns. I also have a friends BKPrecision470 that has no listing. Anyone know?

bad Looks like x901 bad. Ordering a new one.

pics here are 2 pics. btw, FR901 good

So checking to see if a monitor on the shelf works which I thought I just put there a month ago.... I plug it in and it works. About to label it and it goes dark. F901 blew. I inspect Flyback and reflow it. HOT seems to test ok and I put a new F901 in and monitor dead. Fuses fine. Put a new b+...

neck I pulled the neck and all continuity was there. I decided to put in a 27 inch WG neck I found in my stash and it worked. So at least I know the problem is in the original neck pcb.

Neck I also have a p719 neck from a 27 in 7400? 7500? I forget model. Interchangeable?

Blue Thanks. I will look at traces now. If tranny is bad, will C3782 work?
