It has not been reading blue-ray discs for a while, but that was fine as GT4 almost never came out of the tray. But now I have no video displayed on the tv, whether with the RWY cable or the HDMI.
Does anybody know a highly competent electronics wizard that might be able to take it apart and fix it?
What you're talking about with the blue discs is not Blu-Ray but the blue PS2 discs that are CD-ROMs rather than DVD-ROMs like most PS2 games which are the silver discs. There are 7 categories of discs PS2s play:
PS1 games: These are all CD-ROMs and are black. A system can play all other categories of discs but won't play these if there is an issue with the laser.
Blue PS2 games: These are CD-ROMs and are blue. A system can play all other categories of discs but won't play these if there is an issue with the laser. Usually used Super Trucks Racing to test systems for this since it was cheap and common.
Silver PS2 single-layer discs: They are silver and DVD-ROM. A system can play all other categories of discs but won't play these or Dual-Layer DVD discs if there is an issue with the laser. We always used a Dual Layer DVD-ROM to test systems since if it can play Dual-Layer DVD it will do Single-Layer. There is a Wikipedia page listing all of the Dual-Layer DVD-ROM games. We used ATV Off-Road Fury 4 since it was cheap and common.
Silver PS2 Dual-Layer discs: DVD-ROMs. Hold twice as much data as Single-Layer discs. Harder to read than Single-Layer. Explained more in the Single-Layer section.
DVD movies: Usually worked if the Dual and Single-Layer games worked. Any movie works for testing.
Dual-Layer DVD movies: I don't know how many of these are out there. Should work if Dual-Layer games work.
Music CDs: Another category to test if this is important to you on a PS2.
About half the time cleaning the laser (not just the lens, remove the black top cover of the laser assembly and spray the entire laser assembly with your air compressor as well) made all types of discs work. Make sure there is nothing stuck to the spindle either. Plenty of tutorials online. The hardest categories to get working right are Dual-Layer DVD games and Blue PS2 CD-ROMs. There were quite a few times it would be only the Blue discs that would not work. If cleaning the laser didn't work a replacement laser usually did but not always. At that point you were looking at corrosion problems or a bad bridge chip or connection to the bridge chip which we only fixed very late in the life cycle of the business when used PS2s went from $30 at the bottom in 2010 when we started to $100 during COVID.
AV ports do wear out. Of course clean the connections first before committing to that near-full-teardown job of soldering in a replacement. We never did replace one since the system was too cheap most of the time to justify it and instead handed it back to the person. These days it seems like most retro systems are worth saving but for the longest time many weren't (such as ones that had multiple issues) except for someone doing it for fun. I don't fix video game systems anymore except for my own.
Another thing to check before you solder in a new connection is to try it on a tube TV. Some newer HDTVs will reject resolutions under 480p or custom resolutions like other retro systems have.
