After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:-
1) Check the area of your repair for unsoldered or poorly soldered
connections. Check the entire board surface for solder splashes and bridges.
2) Check the inter board wiring to ensure that no wires are pinched or
contact high-wattage resistors.
3)Check all control knobs, shields, covers, ground straps and mounting
hardware have been replaced. Be absolutely certain you have replaced all
the insulators.
4) Look for unauthorized replacement parts, particularly transistors that
