<p>Success! After soldering the wire where it needs to be, red is back!</p><p>The image is horizontally squished because I’m using a resolution of 1152x368 instead of 576x368: the PLL of my GPU isn’t capable of driving such low resolution but if you double the horizonal timings and the pixel clock, it looks the same to the CRT.</p>

<p>I tracked it down to a loose wire at the tail end of the signal path, right where it’s supposed to enter the tube. The signal on the red wire is a respectable 65V here. And there’s an 800V signal on the same PCB!</p>

<p>With the new adapter, the CRT is working, but the red color component is broken. In the image below, the black rectangle is supposed to be red.</p>

<p>The CRT has a resolution of 576x368 at 60Hz. Non-standard timings and a pixel clock that is too low for the Intel iGPU of my X220 laptop. In the past, I used xrandr to set correct timings, but that&#39;s a pain. The custom EDID contains 1152x368/60Hz timings. You can now plug in the VGA cable and everything magically works! Zero config!</p>

<p>After 3 years of being dormant, I&#39;ve picked up my Sony CRT project again. The goal is to make an 8&quot; monitor for retro gaming. All it needs is a VGA interface board and a 120V DC power supply. Soldering the power board is for tomorrow. Today, I tackled the easy stuff: replacing the contraption on the left by the new PCB on the right. I added an I2C EEPROM to the PCB to store the EDID.</p>

<p>My deepest condolences. Martin was a gem. 💔💔💔<br /><a href="https://mastodon.social/@pilky/114008572002612525" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://</span><span class="ellipsis">mastodon.social/@pilky/1140085</span><span class="invisible">72002612525</span></a></p>

<p>Every MAGA is an accelerationist actually. They&#39;re accelerating collapse of America to be surpassed by China.</p>

I guess I know where that money went to...</p>
