Hi, you give very good idea! I check it and transistor 2 pieces was bad. Here is quesion, is problem in transistors or maybe they broked because problems with contacts from mother board to printhead? My electronic mechanic give me that idea. What you think about it? Because if change only transistors and after them wil be contact in wrong place, its can dead again.
Thanks ypur videos are useful! Do you know if the power supply if not conected to any boards puts out voltage? I have a sc540 that dosnt power up but led on main board and head distribution board flash when power goes on sort of like there is a fault with headboard head cable problem. No fuses blown i will check transistors after watching this.
Thank you for ur good comment and i hop that this solution will help u fixing ur problem for the probleme that the machine not going on it depend on many things starting by the the button that make the machine on . Wires from the main board to the control pannel just try to check step by step and i hop that u will fix it
@@MarhabAZouhair yea i only get 5v for a second no 20v or 41v output to main boards. But im not sure it does output the higher voltage when in standby. I will pull out and test the powersupply board tomorrow.
@@chrisranyner4890 How'd you go mate? My machine has an issue and I pulled out the main board it outputs 41.0 no load. That said it's got Heat marks so after I test output under load first I'll be replacing it.
@@syyedshakeer6642 no sir it was just c4131 that was dammaged not the other one so i just changed it with the same number and its done everything was working good
@@syyedshakeer6642 I have been told by a certified electronic repair tech (who repairs Roland circuit boards to always replace both the A1746 and C4131 transistors together, as they work as a pair. They are pretty cheap and it would be more of a hassle to remove the board at a later date, so better to replace the pair while you have the mainboard out of the printer.
Thanks man but im still a newbi hahaha the probleme here is technical support lot of money thats why i was looking all arround the internet to know how to fix my probleme and thats whst i find they was speaking about the fuses and i tried to change them 😎 thats how i find the solution hahahaha and im sharing with u my fix
@@johannienel1 hi mr johan yes it was good but i was stupid i tried to clean it with air compressor 😅 and now its not working i have error 0101 and that mean initialization limite in service mode has not been done could any one help 😂😂😂😂
Brother ,I have the same Problem. I see you Solder wire to where the small ceramic fuse holder were. now what are the specs on the bigger fuse you adapted?
Hi bro this solution is soo good because it gives u the right to replace the fuse when its damaged i replaced the original fuse with a fuse 1amp and its still working fine for now 😎 i hop this solution will help u . But try to see the transistors if its working good or not i made anothrt video to fix the blowing fuse 😎 i hop the will help u
@@MarhabAZouhair . I tried the fuse but then also found 2 transistor were damage, i change all damage parts but when i turn on printer it gave me scan motor error and error code 0040, then the fuse and transistor burn up again. you think the print head is damage? and how do you test print heads?
Sur please check the cable from the printer head to the motherboard remove it and check if there is a short if its damaged just tey to change the naps please check and answer me

Great Post , did you also change transistor A1746 the one at the side of C4131 ?
Yes sir that was the cause of my blowing fuse 😂 after that everything was cool and working .

Thank u mr jon for sharing this information with us all my respect
Awesome video. Thank you for sharing sir! You seem to know the printer very well? I have a SP540V and still busy learning it.
Any chance you could help with some questions about these machines please?
