JVC TV model AV-27730 relay clicks repeatedly

On this set the relay would start clicking as soon as you plug the
power cord in. I found a bad solder connection on pin 6 of the vertical
output chip which burned the board and put a crack in the chip. The
original chip was an LA7832. I replaced the chip with an LA7830 but the
set still clicks. I suspected a bad cap in the power supply and ESR'd
all the electrolytics but found no bad ones. I have no schematic for
the set and am not quite sure as to how to proceed with troubleshooting
this thing. Does this problem sound like anything familiar with this
model or can anyone offer some suggestions as to a procedure? Thanks
very much for any assistance. Lenny Stein, Barlen Electronics
