Question about JVC AV-48WP30 48" Rear Projection Television
Thanks for getting back to me
I'm not real familiar with a soldering iron, is there a chance i could damage the tv for good if i attempt this? If not i'm willing to give it a go.
You can easily cause major damage, if you are not expereienced with electronics or soldering at all i dont think i would try it. It is pretty simple but things can go wrong. A good repairman will run you $300-$500 which isnt really that bad when you compare it to $2000-$3000 for a good new set!
Let me know what you want to do!

Tips for a great answer:
It could be a problem of cold solder joints, or solder joints
on the main board which have cracked over time due to thermal expansion and contraction
of the circuit board. Repair is to find and reflow the cracked joints. You may
want to consider hiring the services of a reputable repair professional to deal
with getting your set back into normal operating condition.
However TV's attempt to protect themselves from damage by
shutting down. Your unit has three main ways to protect from damage.
The TV monitors various DC voltage supplies. If one of the
supplies is missing. The TV shuts off.
The TV monitors excessive high voltage and beam current. When
the TV detects that one of these is too high the TV shuts off.
OVER CURRENT PROTECTION
This will activate if excessive current drain on the 130 volt
supply line. If the TV detects this supply line is too high the TV shuts off.
Most units made in 1999 have a diagnostic mode to help
determine the cause.
