Thank you for reply.
No, I am not capable of this work myself.
Will a technician definitely to able to ID the faulty capacitor and fix it (for about £60) or is there a risk that he/she will not be able to ID the fault. My TV has already been to a repair shop once for this problem with no improved result.
With a new TV at £250 ish, I am not much inclioned to spend £60 on a five year old one if 'repair' mihgt fail and still cost £60
