Sometimes a part can go shorted, and an over voltage occures somewheres thus causing another part to blow. This can be anywhere from in the power supply to any of the other boards.

The set would have to be serviced to determine the cause and what was damaged. Most likely there will be the need to change some boards. Most of the service is done by a combination of board replacement and some component replacement depending on the exact type of fault.

Sounds like either something went pop on the main pcb or in the power supply. Will need a repairman to take a look. & Just a caution if you're feeling adventurous, don't do it yourself unless you know what you're doing!!

Check the O rings on the big metal striker, make sure that you have the spring on the back (where the stock would have went) in the right hole on the back plate. Make sure that your velocity is set to a reasonable level.

No Picutre


someone shot your tv.





no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..
