Old man Posted August 9, 2020 Share Posted August 9, 2020 low A just quit working. If you hit it just right it sounds, but otherwise it sounds very quietly or not at all. Quote Link to comment Share on other sites More sharing options...
- T - Posted August 10, 2020 Share Posted August 10, 2020 This is typically caused by dirt, dust, dead bugs, etc. on or under the dimpled rubber key contact strips beneath the keys. It can occasionally be cleared by spraying a can of compressed air (NOT CONTACT CLEANER - NO LIQUIDS UNDER THE KEYS - EVER) around and under the affected key(s). If this does not resolve the problem, then replacement of one or more of the dimpled rubber contact strips may be indicated. New strips are available from various sources, and it can be a DIY project. There are photos here, as well as YouTube videos that illustrate the process, but even so, it is certainly not for the technically faint of heart, or those not adept at using tools on delicate instruments. At the age of the WK-3000, and with the current labor rates for professional repairs, charges could easily exceed more than half the cost of a newer replacement keyboard. So, that would need to be taken into consideration, before entering into any repair agreement. Quote Link to comment Share on other sites More sharing options...
Jair77 Posted May 7, 2022 Share Posted May 7, 2022 yo limpio las teclas d mi wk3000 cada 2 an~os; desarmo las 3 laminas metalicas que se encuentran bajo el teclado, remuevo con cuidado la placa base PCB, limpio los contactos de las gomas y los pads con toallas humedas y seco con servilleta de papel, luego coloco tinta conductiva (con forma de pintura para un~as )que venden en las tiendas de refacciones de partes electronicas, dejo secar 1 hora y regreso las gomas y la base. la base de las gomas tiene un ligero toque de carbon conductivo parecido al de los controles remotos que con el calor tienden a desgastarse y a ensuciarse provocando malos contactos entre los pads sensores del speed o touch. en mi caso yo estudie electronica, pero cualquiera que tenga cuidado pudiera darle limpieza a esa zona del teclado. aun asi te suguiero que lo lleves a un servicio tecnico para que realice dicha limpieza interna de los contactos pads y gomas bajo las teclas.
