[No picture after buzz off install]

Figured the issue out. The j204 wasn't making good connection to the cpu motherboard. Cleaned the connections with deoxit and it sprung back to life and without any buzzing! Woohoo!

I turned the knob both ways and there is no image on screen at all. Just sound. It was working perfectly until I installed the buzz off. This is a rare vectrex that has the soldered sound ship instead of being socketed so I had to cut a trace and run the 3 wires to the sound chip. I turned the knob both ways and there is no image on screen at all. Just sound. It was working perfectly until I installed the buzz off.

Hello guys,

 

I was doing a buzz off install for a customer and after the install, I get sounds, but no image. I checked the voltages from j204 and they look fine, didn't really touch anything on the crt side or power board. So I am kind of perplexed. If i turn the lights off, there is a faint glow of the filament. I do a ton of mods, but this is the first time I have worked on a vectrex. Any ideas would be great!

[What capacitor is this on NESRGB?]

Just an update, Tim sent me another nesrgb board and that one worked perfect along with another I bought and put in a buddies NESRGB. That board must have been defective to begin with.

Try something less violent.

Really? I use that on every forum and it's just the same as my in game tag. They are that overly sensitive to that name? Wow.

Soldered the Twin FC adapter out of order so had to unsolder it, while doing so overheated a little the boards and had 3 or 4 capacitors move out of placement and lifted 4 traces on the adapter board.

In the end nothing was permanently damaged and I was able to re-wire the lifted traces and put back the capacitors and it all worked out.

 

My NESRGB was from one of the first batches (1.1 or 1.2) and I had to reprogram the CPLD a couple of times, now the page doesn't link anymore to all that jazz

but there were a few releases and had to use an Altera Blaster etc... etc... I am almost sure I am on fw ver 1.6 (never had time to get to one of the 1.7 as 1.6 worked for me)

 

So, I have been trying to get this nesrgb to work and it's driving me insane! I get no. video. no. sound. I pulled the ppu from my other nes and placed the ppu in the socket with the nes rgb installed and works perfect. unsoldered the ppu from the nesrgb and placed it in the socket without the nesrgb board, it works perfectly as well. Looks like something is wrong with the nesrgb board. I will look the board over again and see if something is unsoldered on the nesrgb somewhere..... If not, I hope I can get a replacement from tim, since I have to order 2 more for my other NES and Famicom. and the master system FM board.

Hey guys, I just wanted to know if anyone here can get my profile approved. It's been 4 or 5 months and I still cannot post on assembler games. My profile is BringerOdeath, the same as my profile here. Thanks in advance!

I messaged him and that smd cap isnt necessary for the board to work. I checked continuity and there is continuity with all ppu pins except 2-9 and 14-17. This is normal I read. What was the issue you were having?

Hello Guys,

 

I installed an NESRGB and I am getting no signal at all to the tv. I looked the board over and I saw that SMD cap had fallen off. I need to know what cap this is!
