Scrambled video on a non-modded v9

**modicullus** · 07-28-2004,11:35 PM

A fella asked me to take a look at his v9 PS2 (never been modded) and see if I could get it working. He told me that it wasn't booting anything. So I assumed it was probably the dreaded v9 syndrome.

When I fired it up, there was nothing at all. No lights on the reset or eject and neither responded to anything. So I ripped open the PS2 to find that the reset/eject ribbon connector was only in half-ways (on an angle). I figured this was the source of the problem, so I decided to do the 5v mod to it while I had it apart (actually a dumb idea - I should have fired up the PS2 first to see if the ribbon cable fixed the problem).

After I finished the 5v mod and put the PS2 back together and fired it up, there was no video on my little LCD screen that I use on my workbench. I mucked around with it abit and then decided to try hooking it up to my TV (thinking maybe it was a problem with my AV cords or something). When I hooked it up to the TV, I got some video, but it's all scrambled. I can make out some of the text and stuff on the screen (ie - browser, system configuration, etc), but here's a pic I found in another thread that looks alot like what this machine looks like:

I double-checked the 5v mod connections and everything is clean (actually, the PS2 will boot discs - I can see this through the scrambled video), so I don't think that's the problem. I double-checked the video connections on the main PCB, and they all look good.

If I had to guess, I would say the reset/eject ribbon connector caused some sort of short when it came loose and fried something. Dunno...

Anyone have any ideas/suggestions?

You shouldn't have to repair a non modded PS2... Should've taken it back to where ever you bought it from and exchange it. That's Sony's part if you never touched the inside. But now you did... Maybe you can put a sticker back on and attempt to return it.

The machine was out of warranty and the guy had already cracked the seal (thinking he could fix it himself, but once he had the cover off he abandoned that idea and brought it to me).

I see...

check aroudn the video chips on the board

**modicullus** · 07-29-2004,01:44 PM

I checked the entire board over and didn't notice anything out of the ordinary. I had also checked all of the fuses as well (forgot to mention this in the original post).

I dunno if it's an NTSC/PAL problem (although it does say NTSC on the back of the PS2). I was also wondering if it's a problem with the AV cables. I've used two different cables that work fine with other PS2s, but I'm wondering if for some weird reason it requires component cables or something like that. I tried changing the digital out and cable output in the system configuration (I could kind of make that out on the scrambled screen), but changing those settings never helped. I also removed the battery for abit - just for the hell of it. Didn't make a difference...

Just talked to the guy,... and I asked him to be a little more specific about the problem, and he said he was playing it when he turned it off and fired it up to put another game in, the video was scrambled. He turned it off and back on, and the video was fine. I guess everything worked great for another month, and then when he fired up his PS2 to play a game, the video was scrambled again and this time he couldn't get rid of it.

So it confirms that the 5v mod had nothing to do with the scrambled video, but I'm still at a loss as to what would cause this. Possibly a good power surge fried the mobo? Anyone know if a faulty reset/eject button or cable would cause something like this?

Anyone else have any ideas? I've actually bought the PS2 off of him for parts, but obviously if it's repairable, I'd like to go that route.

Anyone know what else could cause the scrambled video? Maybe a broken eject/reset ribbon connector? Just guessing...

don't know liek i siad u can try to replace the video chips

**modicullus** · 08-10-2004,03:53 PM

yeah,... but that's a lot more work than it'd be worth. I was actually cruising through some other forums and I ran into a post where a fella said he had a few machines with this problem. What he had done to each one was take a heat gun and apply heat AROUND the video chip ('emotion engine') and gently press down on the chip. This solved his problem on all three of his PS2s. He assumed that when prying the bottom casing off of the mobo, the contacts on the chip were pulled apart. I'm thinking that may be the problem with this one as well (although the problem appeared before the PS2 was even opened - so I'm thinking that it's possible that the PS2 overheated and the poor solder connections on the chip came loose - just a guess).

Unfortunately I don't have a heat gun, but I'm going to take a closer look and see if there's something that I can do with a soldering iron.
