Voxel Posted October 18, 2020 Share Posted October 18, 2020 Have you knocked your machine. Also are you able to open it, re-seat the IC's and check nothing has fallen in (including fluid), causing the moving parts, connectors (inc cartridge), switches, leads, etc to be affected in any way. I'm also wondering if one of your capacitors may be on the way out, or is being shorted out by dust or debris. Quote Link to comment Share on other sites More sharing options...

ReilyReed91218 Posted October 18, 2020 Share Posted October 18, 2020 Try reseating the IC's, using deoxit on the switches and ports, and make certain that you're wearing antistatic protection when you're dealing with any old circuitry.

Is the TIA soldered to the board or does it use a socket? If it is soldered, try resolding it and if it is in a socket, try a new socket and cleaning all the CHIP terminals before reinstalling it. The CHIP may also be defective. Quote Link to comment Share on other sites More sharing options...

PAL TIA = CO11903 NTSC TIA = CO10444 (there's a typo on the Best catalog page. CO10444 is correct, with only three 4's.) It's probably better to call them if you haven't ordered before.
