I use to repair all kinds of electronic devises i have a MARK 7 FENCE CHARGER..i believe it had a power surge..after cking it out..my educated guess is the SCR power rect has an open gate ,and need to be replace...as 27ohm 5w resistor smokes..any ideas?
Hello- Sorry- no good news here. 'Self clean', or self- destruct' as Techs call it, has burned out a circuit or switch somewhere on the unit. The best case is a burned wire connection. The worst case is control circuit failure.The solution involves on-site diagnostics by someone qualified to make sure repairs are needed and done right. Inspection should start at power cord and move to control board. Multiple failures can occur during 'self-clean', but sometimes only one part will fail. Find a good Tech to look it over and give you an estimate before repairs. Remember- Don't 'self-clean'! It's costly and dangerous. Please acknowledge this post if helpful.. Have more info if needed. Thanks-- Ed
this is a job for an advance electronic repair tech...try the manufacturer..next a tv repair shop..then an Audio Install shop...if that doesn't work out..i'll personally try to fix it..for lest than anyone else..its probably the tranformer output circuit overrun..that part of the board or component wil have to be replaced...good luck
You will need to get a service manual and trouble shoot what amp. circuit is defective. if you have no solid state printed circuit board experience, you really should take this unit in to a repair shop and have it estimated. There is no quick fix for this unit. Good Luck.
