Greetings,
I just replaced a the failed (shorting) HV Splitter / Focus Combo block in my LXI RPTV. The original was a Sanyo 220493-3 and I replaced it with the 4835 310 57402 HV/FOCUS COMBO BLOCK KIT. After replacement the TV makes a buz (seems to come from the three tubes, but I'm not sure) that sounds a bit like shorting high-voltage. On power-up the screen pulses blue and blue/green and eventually the tubes turn off (the TV remains on). Occasionally I can see arcing in the base of the tubes. Any ideas on what could be wrong still - on what to check first? Thanks, ~Aaron |
