Have the same problem on my JVC LT-26C31BJE. This is the second time when it first happened a year ago took it to a repairer near gatwick in Horley fix was to clean it all up and reseat boards etc (well they didn't charge for any boards etc so I presume thats all they did). Have tried cleaning all the connectors etc but still no picture so will prob have to take it back to them again but don't want to keep spending £90 each time if this is going to keep failing !
