[TechAssist] Re: Help-mag.PTV775-Ah01 low b+

Thank you damon for the info.ken and jason for the cross.
This set has two hor-outputsQ802 and Q906 = 2539. Q906 was the first one i
pulled it check as a good intedgrated output it is next to the flyback Q802
was shorted on all 3 legs i had no data on it so i thought it was a switcher
.prombley cause i got a head cold why i missed that Q802 and Q906 had the
same #..lol
Thank you so much for helping me with this .I had a nte2353 hanging so i
replaced Q802 set is working but there's fant retrace lines somtimes.I check
a.m........Have a Great day .......bob
