ink system has failed error: oxc19a0035. what is the solution?

Ink system has failed error messages on hp photosmart c5180 caused by faulty capacitor on systems control board at right hand side of machine. The capacitor designation no. is C228 and is roughly in the middle of the printed circuit board. It is green and roughly 1 cm tall and is a 330uf 10volt component which is not high enough rated for job. You can see the faulty one straight away as the top of it is domed compared to all the other ones on the board. It is easy to get to and change provided you are proficient with a soldering gun. Unplug unit and lift ink draw, you will see 1 black torx screw holding side panel and 1 at the rear of unit. Remove and then you can get side panel off if you put unit on to it's left hand side. Use a flat screwdriver to prise plastic clip off at centre top and remove. To remove systems board, unscrew 5 silver torx screws and then you can work on board without having to unplug. If you cannot solder yourself, ask a competent electronics engineer to fit new cap. for you. I got replacement cap from Maplins at a cost of 26 pence. The one I got is a 50volt one and bigger than the original which is fine as it is better able to do the job and still fit ok. The old one was causing an AC spike to appear on the LT lines and corrupting the microprocessor.
I tried all the so called cures off the net and was getting to my wits end with this machine, it being a superb printer when it worked. People are throwing these machines away not realising that all it needs is a 26 pence part and 15 minutes time. This part was an instant cure as the machine was giving various errors and looping as well as going crazy at power up. After what I have read on net about other peoples experiences with HP tech.
I cannot believe that they do not know the cure for this fault and can only assume that they are more interested in selling you a new printer.
