IMHO if you`re REAL careful you ought to be able to do this. Even if the tv hasnt been powered up for 9 mts you need to make SURE that the crt is discharged. First of all; old rule of thumb when working with high voltage- keep one hand in your pocket and dont touch anything, especially wires or anything else having a lot of dust on them. If you dont understand why, maybe you shouldnt do this after all. Tape a DRY dowel rod a foot or so long to the end of a foot or so long lamp wire. Strip the insulation from the end. Dont tape the bare wire to the dowell rod. Connect an aligator clip to the other end of the wire. Connect this SOLIDLY to the metal chassis of the tv. Wear rubber sole shoes. Holding the dowell rod by the end far from the wire, stick the bare end of the wire in the crt hole where the suction cup goes. Wiggle it around, take it out and do it a few more times. Do the same to the wire that goes into the crt ( has a suction cup on it.) You can connect the suction cup to the crt. Holding the pcb by the edges align the socket on the board with the pins n the back of the crt. It only goes on one way. Gently wiggle it on the crt.
OR,BETTER YET forget all that and lay the board inside the tv case, put the back on and call a real repairman AND Let him put it together. Dont touch any wires or metal , except the grounded case- most parts are static sensitive nowadays
Btw what are the symptoms.?
