Hello I have PSX DVR (7700 model) It was working properly all these years then I shortcut it accidentally ( don't ask why) Now it won't power on. No red light stand by. When I turn on, it make a quiet click sound and that it. I assume I damage the PSU? Is anyway I can fix this problem or any handy method? On next saturday, it is a skip day. If I can't fix I will have to throw it the whole thing in the skip and call it a day, so I hoping I can fix it before I throw it away. I can't be bother selling broken PSX on ebay for cheap price. Not worth the time. Any help I would appreciate. Thanks
What you shorted ? That don't ask why won't get you ANY HELP. lol I in 2013 got a DESR-7500 with a serious problem: And I bet you had some similar issue ... lol It did blow some fuses on the motherboard because of that. I had to replace the flat cable and the fuses.
What happen is, I open the PSX inside to sort out the lens due to not reading properly and what I did mistakenly I remove the cable wire then I reconnect back while PSX still power on and of course I shortcut it . (It is a ribbon that connect between from motherboard to the whole disc stray... similar like yours I'm so fucking stupid, I can't believe i done that. I assume I damage the PSU, so it means I have to change the fuses. I have heard that you can replace PSU from fat PS2 to PSX, I wonder if that is true? Is anything that you may can help? and thanks for the picture aswell. Thanks
No, you can't. But I find unlikely that your PSX has a power supply problem. Like I mentioned on my post, the fuses are on the mainboard, not on the power supply.
After "manufacturing" a suitable replacement for the originally screw punctured flat cable I had to replace two power related fuses on the main board. They look like resistors but are clearly identified as fuses on the board markings.
Hello I tried to message you but I can't find the way to message you, alot of things has changed on this site since I last log on. I decided to go back and fix my PSX DVR again, Now you saying you replace two fuses that's look like a resistors on the mainboard. Do you mean two fuses on the PSU board or just actually mainboard. It just differcult to know where it exact they are, I can take a picture of my PSX DVR motherboard and could show it to you? Many thanks!
Update I assume when you said fuse look like a resistor I believe you meant this I saw one of that on the PSU board, I can understand why you said it looks like a resistor. I took a close up on my fuse and It doesn't show any sign of burnt or snap in half or anything like that. I better replace that just in case. I don't see a second fuse on the PSU board yet, maybe the mainboard?!? Or maybe I just have one fuse due to that I have a 7700 model. I better start examine it soon. Your help alway be appreciated. Many thanks
Blimey I don't know where to start! Is that what l-oliveria is saying? I have upload two picture of main motherboard from top and bottom, Hopefully someone can spot those uses.
I had and still have broken PSX (it stucks while checking the board), but at least you can check the fuses using my list from this thread and replace them. Any PS2 slim model would be fine as a donor. You can order fuses from China as well. http://assemblergames.com/l/threads/psx-desr-5000-5500-7500.56197/
Oh fantastic!!! at last we got somewhere. Thank you guys for your time and help. Just a quick question, How can I know which fuse is broken or working. Do I buy a device like a meter reading? Thanks
Citrus, you missed PS3001(no pun with your forum name is intended), which looks like a tiny resistor, protects the standby circuitry and is likely the one he blew.
