    Here is the link for boardview
    https://www.alisaler.com/toshiba-c55...a02-boardview/

    Check voltage on all coils and see if any rail is missing.

    You can try this bios also

        The only defective component who give you any pictures on your internal or external screen is the GPU, or something around it.

              it is integrated to the AMD processor if all the power rail is present.. the integrated gpu most likely it gone bad..

                      So i guess no one encounter this on this laptop brand... so gpu/processor reflow again 50/50 might death or alive

                        if the gpu fails.. reflowing doesnt repair it you need a new processor..

                          maybe the first attemp to reflow it... kills it.. this is the problem of most integrated processor and gpu.. it is disposable..the processor is good but the gpu is bad theres no fixed there but to replace it..

                            just replace the processor/gpu.. to solve your problem.. make sure when you buy a new amd processor just indicate to it the balls must be lead type dont buy the lead free type just a suggestion the lead free type if you dont have a reflow machine you will definitely kill it due higher melting point of the lead free solder. mahal din ung amd processor tol.

                                before you attempt to replace the processor.. try to find shorted cap around the processor area in some cases thats the only problem but if you cant find shorts definitely your only option is to replace the amd processor

                                      you need to stick to the original value.. that cap value is there for a reason..a 10% tolerance maybe use but 470 is way too high...its almost 50% tolerance,, my opinion...
