Palsonic 3498 TV info needed
Hi,
A mate of mine's Palsonic 3498 TV had a power supply fault which sent the main B+ voltage massively high. He's corrected that fault, but now the vertical output stage is pulling very high current and has taken out a fusible resistor. I'm trying to help him by phone and e-mail. Has anyone experienced this fault before, and can tell me to tell him which components are probably cooked, or alternately got a schematic of this TV to speed up the process? Thanks!  Cheers Bob |
