I replaced C603. This was the only one I'm not 100% sure. This is the part i replaced it with. ( http://www.mouser.com/ProductDetail/Kemet/PHE426DJ6100JR05/?qs=%2fha2pyFadugE%252bCDfNBE2eZZot9r7qUftyz%2feC8t3%2fCQx9uFQTFR7j%252bGzRlmBC6GU ) U601 is pretty far off on several values. Which leads...

I replaced C305, C811, C302 which didn't help. I measured the remote by placing it into a breadboard and testing the V-hold pins (pin 3 and 13) and it measures good. The remote cord tested good for continuity and I was able to verify that pin 3 makes it to R622 and that 13 makes it to the...

Ohmerone: Attached you will find the picture of the board. If there is anything you would like to examine closer I can provide them as well. I scoped pin 3 on U601 and there is no saw toothed waveform. It's mostly a steady 16v with a 11v dip every 20ms lasting 100us. I doubt that is correct...

nuterpacman: I replaced C610, C607, and the TDA1771. Could perhaps the one I replaced it with also be bad? I did order the TDA1771 off ebay. ohmerone: Both U601 and U701 are correctly orientated as they indicate pin 1 and they match the board markings. I'm not sure what you mean by an open...

update I measured the the yoke plug marked vertical and it reads about 7ohms of resistance. I don't know if that is enough or too much, I can't find a reference. U601 has 30V at pin 9. The chassis does not have a vertical hold POT populated. The remote board has a vertical hold, and it...

I have a monitor from a Sega Emergency Call Ambulance, which is a K7500. It has a vertical collapse issue that starts off purple and gets more and more red as time goes on. I don't leave it on very long in this shape, I've just noticed it as I've replaced parts trying to get this monitor to...

Works I did as you suggested and re-flowed all the solder joints and it works perfectly now. Thanks for the suggestion. I also tightened the pins on the interconnects to make sure it wasn't loose.

I recently got a cocktail Space Invaders out of a poorly kept warehouse and repaired the boards and recapped the monitor back to life, but it has a strange issue. When you even slightly bump the cabinet, or gently hit the surface of the cocktail the monitor will wiggle and sometimes (if the...
