    Update (2023): Matt Ross (6tanks) has now written an updated mod for this TV. Please follow this guide for the best resistor values and solder points. Thanks to this guide, the horizontal screen alignment problem shown in the video is solved:

    Awesome job. Thanks for the upload... I have a pvm2030 that had intractable geometry issues until I had it recaped. Now the geometry is virtually perfect. I recommended you give that a try...I've got pvms and a bvm but I prefer to play on my 32 inch wega. The size more than makes up for the loss in sharpness. I use the shinybo component to rgb. I don't believe it adds any noise.

      @spencer6891 2 роки тому

      I just posted about something similar with mine (possibly the same thing). Whenever a lot of black/dark appears on the screen, the TV automatically boosts the brightness/contrast, and vice versa. For example, a dark text box, or sudden black crop bars on top and bottom (like when you press the Z button when playing either of the N64 Zelda games) makes the entire screen go brighter. Even going from a slightly light scene to a darker one will trigger it. I do not see any option to disable this in the user or service menus. I don't even know what it's called but I'm assuming it's what Toshiba advertised as "black level expansion". I hate when a marketing gimmick ruins an otherwise nice product.

    Please update if you do work out a fix for the shifted image. It’s also a bit stretched on the right.
    All my Toshiba sets are shifted left even unmodded with HD Retrovision cables. I assumed it was because they use tri-level sync like an HDTV since HD Retrovision’s “Sync Jitter” page describes that causing some TVs to shift left. Obviously, these aren’t HDTVs but that still might explain it.
    Also, FYI, Sony Wega is pronounced “Vega” with the Latin pronunciation of W. ;)

    • @BasementBrothers
      @BasementBrothers  2 роки тому +1

      Interesting about the tri-level sync. I hadn't heard of that issue. So adjusting the position in the service menu doesn't fix it?
      I've heard people pronounce it Vega. I guess I wasn't curious enough to check it before recording.

      @emmettturner9452 2 роки тому

      @@BasementBrothers At 9:05 you mention the same issue with it being shifted left and that it can’t be completely fixed in the service menu. You said Bratwurst had an idea about how to fix it for both of you. I had hoped you found a solution.
      You can’t fix it by adjusting H-position in the service menu because it is also unevenly stretched. If you could adjust it to the right enough to correct the left edge you would be losing as much or more from the right edge. Not talking about usual overscan here though.
      It may not be related to bi-level or tri-level sync at all. I had just read about it when I got my HD Retrovision cables several years ago and always thought that was it… but all my Toshibas CRTs have Orion tubes inside. Orion is known for having a weirdly uneven stretch. I believe a Lame Gaming or The SegaHolic video mentioned this in their Toshiba TV RGB mod video (whoever it was demonstrated with Contra Hard Corps).

    My only question is why bother switching back to the original circuit when it was never used? I didn’t bother, just blanking on/off

  • @t0nito
    @t0nito 4 роки тому +1

    You don't need a switch, just do like our European TVs, scart devices feed their RGB blanking voltage through the Scart plug, turn on the device the TV switches to RGB mode, turn off the device the TV returns to composite/TV mode, that's how it's done here, there is also a signaling pin to make the TV switch to AV automaticaly but you don't need it just switch to AV on the remote. You can still use the resistors behind the scart plug to reduce it to the proper voltage the jungle IC expects for blanking.

      You may want to try the S-video luma input as well, if you haven't already. On my RGB modded sony, I get bad picture shift if I use composite, but using luma from s-video is fine. As I understand it, this is due to the composite signal going through a comb filter, causing the picture shift.

    Great job on the mod! Hoping to RGB mod a few CRTs I found for free on Craigslist. I'm curious - how expensive was the mod, not including the price of the TV or any SCART cables? And how much time did you spend looking for documentation and reading tutorials?
    Also, how has nobody commented on that beer pour?

    • @BasementBrothers
      @BasementBrothers  4 роки тому

      Thanks for the feedback. The beer footage is something of a recurring joke we use on this channel, and I believe it was commented on already in the Secret of Mana 3 video or the NES mod video, where it was also used. The original joke was that it was a very careless, half-assed, rushed pour.
      It's very hard to put a price on this particular mod. It's almost free if you already own the tools. The main cost would be buying any supplies that you don't already have, but if you already do some modding, you may already have most of the tools and supplies needed.
      I paid 5.99 pounds for the scart connector from retrogamigcables (about $7.76 US), plus 10.24 pounds priority shipping to the US, which is high, but I always buy some other cables or something I need when I order from there to combine shipping. As mentioned in the video, there is a much cheaper connector you can order from China on ebay for about 2 for $3.00 if you're willing to wait a month for shipping.
      Then there's a handful of resistors, caps and wires. Very hard to put a price on these things, since I typically order these in bulk for $20~ large packs on amazon or Jameco. I don't know anyone who buys one resistor or cap at a time.
      The main cost really is for a good soldering iron, dremel tool, drill and bits. But these are all investments on things you can use later for other projects.
