Fighting with ps2 and matrix clone
Fighting with ps2 and matrix clone –
I used the search tool but I haven't found information on how to repair the problem I have.
A little history:
I had a silver play2 slim with swap disk for years and never had any problems, always believed that load discs are the best option, especially after the problems I'm having.
A friend of min has a slim play2 also, the model is a v15, motherboard gh-52-51 and SCPH-77004b PAL (EU). As I have a soldering iron and some skills, he asked me to install a chip that he had acquired, a modbo 4.0, at first I said yes but after seeing the microscopic soldering and having only a 30watts iron, I told him to wait and I have adquired a 14w , 0.7mm smalted wire (the une used in transformers and inductors), a glass magnifier and a cheap microscope with diodes that is very useful to inspect soldering points.
Well, once I found the right schematic I started to solder all connections, once done, tested with the multimeter and the microscope, I didn't have shorts and looked well.
Once all was reassembled I turned on the ps2 and saw the logo matrix v.19, popped into my head that this chip is a clone, confirmed, a clone of the matrix itself, the case is that It behaved well, I entered the setup mode, tried a cd of ps2 and well, but refuses to read dvd's, it only read ps2 cd's, after reading that there are often problems with lenses, I changed the lens with a new one, and the same issue, I tried moving the potentiometers of the diodes on the lens, no luck, It didn't read dvd's. Tried verbatim, sony, almost anything that I knew worked with the swaps in the silver ps2, only the ones recorded on cd could be read.
The problem is that after three days I had enough, unsoldered the chip and right after reassembly, the usual failure, the black screen problem I see in all threads, with one exception, the disc begins to spin, the green LED lights and has all the earmarks of trying to start but no video output.
I checked smd fuses that are indicated according to this board, all give continuity, I inspected the soldering spots and no shorts, and certainly the only exception are the vias, soldered to the points I, H, G, and B etc. still have the tin on them. I doubt this could be an issue, tin in a via wouldn't do anything, unless the connection between the two sides of the plate has been "broken" and need to solder on both sides , which seems unlikely, but who knows.
The story is that this is for a friend and now I do not know how is he gonna react, I'm thinking to buying a second hand ps2, but what concerns me is attempting to assemble the chip again as I read these clones tend to give these problems, so I don't know:
If there is a fuse that has escaped me and has no PS () written next to it, if the method of cleaning the tin on the vias must be some specific ones or if it doesn't matter, and finally;
If I can not repair this play2 and look for another, if It's not better the swap method or a matrix 1.93 as I read there should not be much trouble or danger to break the ps2.
I can check voltages, but I have no voltage schematics nor where to look on each chip, a lot of doubts and hours spent on this, and have doubts whether the chip is the problem, and if the next attempt will be a catastrophic failure as this one.
A little help would be very appreciated, I'm pretty lost and do not know what else to read or what to check.
PS2's are dirt cheap these days, just get a replacement off ebay or something, and try again. I just installed a Modbo 4 into a v15 today (GH-051-02) the tiny solder points were a pain to get the solder to stick to, but it wasn't a problem after a scraped away the layer of lacquer that covers the points.
If I was in your position, I would just sell that PS2 on ebay, and buy a replacement, and then try again.
