Re: philips 32pf5320/26 inverter failure

The 24 volt source is fine, has no ripple. I have 3.2 volt input from the control bd. The master inverter bd is 6632L-0189 & the slave is 6632L-0190a.
The orginal master inverter bd had blown ele. caps , open 6.amp smd fuse, & shorted driver IC's. The unit worked ok after changing both boards for about 15 hours. I am ordering repl bds now. sometimes when I probe for signal with my scope, the inverters start working. I am thinking that I got a marginal new inverter bd. can anyone input on this symptom? searching**** ecp

My Philips 32fp5320/26 had a fried master inverter bd, I replaced the master & slave with new bd's & the unit work fine for about 15 hours of run time, then when turned on, no pix, snd ok. The inverters stopped runnung. In deperation, i swapped out the slave bd with the orginal & it worked ok for about another 15 hours, now the same symptom again. I can not find any NG parts on the inverters. Is it looking like I got weak fl tubes? Ed P
