    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Turn out the plastic mounts for the crt are cracking so it has to be done anyways to repair them. I’ll be sure to get a photo or two while I’m at it. Crt has been discharged so all I have to do is remove it.

    I’m working on it but it may take me a little while so I’ll follow up in a bit.

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    I’m not sure if I’m able to get all the values of the Alan of board. I have no way to discharge the crt safely so that may be out of my doing.

    Here’s a logic board photo. I’m working on getting the values for the analog board now.

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Oh that may be hard to find for me. I bought mine after the previous owner recapped its boards. I should be able to get all of the rest at least.

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    I saw on your website that there may be caps on the 250 inverter board. I will see if he can find the values if its not put back together. I also noticed your color classic page is missing psu/analog board as well as missing photos, so I may be able to help you out with that too since I have a...

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    I just found a Facebook post from several years ago about recapping a duo 280, and it shows at least 3 of the caps match the 2300. The other caps aren't marked on the top , so I cannot determine the values of those. This supports your thought that they have the same values, so I will order those...

    Just got confirmation, he misread it. It is indeed a 16v cap

    Oddly enough I found a listing on eBay but they are not smd. Mouser and digikey both show no results for me as well. https://www.ebay.com/itm/131474937090

    Sure. He won’t be able to get the values until tonight, but I’ll make sure just in case.

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Just received the capacitor values from him to ensure they are the same, and noticed one difference. The capacitor that is noted as 330uf 16v on your site was 330uf 18v on his duo. Unfortunately, the power button at the back doesn’t do anything either.

    I’m going to order them on the chance that they are the same. That would save me several weeks of shipping times if they are. In any case, they will be confirmed when I get the duo. Hopefully all goes well. Thanks for all the help and info.

    Great to see! Hopefully the 280 won’t take too long to arrive and then I will be able to recap and provide those values. Should have the same logic board as the 280c as well. Keep up the great work on the website!

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Good that they are of use! They don't show any signs of leaking at all, but you never know if they have failed or not. Only way to rule the out fully is to replace, which he will be doing. Though he is worried that they may not be the cause since there is no signs of power at all and there is no...

    I let him know, hopefully that's all the problem is. He is quite resilient on making the charger lol. Caps should not take too long to arrive so hopefully he can get it working within the next week or two and start diagnosing the display.

    He may not be able to get to disassemble it tonight, but it doesn't seem to be showing any signs of power when plugged in. Any ideas on what the cause may be?

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Ah, completely forgot about those. They suck. I'll warn him against removing those unless necessary for now. He should be good to take apart the rest though.

    He has! He's working on the power supply still since bending the ring didn't work. He hasn't yet gotten the laptop apart, so I will send those photos when he opens it.

    New theory on the cause of the infamous Tunnel Vision problem - Testers needed!

    Well, 3lectr1cPPC, my friends duo just arrived. (He lives in the USA so shipping super fast) I will try to get the photos from him tonight for the logic board and screen. He should be able to test the tunnel vision as well, so if it has tunnel vision, he can also document the process of dealing...
