Well I have had a good run these 6 yrs but last night the screen started not reading all the dashes on the digital screen unless I pushed on it. Mine is 6-7 yr old model with screen on back top. Anyone have this issue and had luck disassembling the screen and cleaning it? Maybe moisture? it stays on a screened back deck. If you push on it it you can read it completely. I have dealt with other screens on other devices that would do this when pinched, etc. I have a major smoking coming up next week for thanksgiving and don't have cash to buy another Master built or worse. Besides that I read they may be worse than my older model and although mine worked out, others seemed to have issues.
