Hi, If you check the images below I'll explain...
Inside my newly acquired JVC 3090EN I found an after market modification which I think is an AM radio hack or possibly a TV mod, you see my CRT on the box is borked at the moment and I wanted to see what's what... and when I saw that hideous cluster of wires soldered together I thought perhaps this isn't JVC's handy work...
So what do you think it was ? - I'm going to remove it in due time and see If it has any bearing on making the CRT in this machine accept a signal, which at present it cannot, no snow or hiss and I think ( see attachment of the RF tuner ) that with the RF tuner case being snapped away like that perhaps this mod wasn't the best idea in the world...
Anyway the chip/IC on board there is a "Hitachi HA1151"
