Zenith 9-1270 Keeps Blowing FX3403 After Installing Kit

07-14-2005, 03:10 AM

It's probably a new defective generic flyback. I couldn't locate an HR
Diemen sub for this chassis. Parts replaced: FX3403, C3406, C3402,
QX3201, QX3208. QX3401 & flyback. Any suggestions are greatly
appreciated. I'll order a rebuilt chassis only if I have to because
these can also be risky.

Check, & replace electrolytic capacitors in the PWM power
supply, & horizontal drive. Rono.
