Subject: [TechAssist] Sony KV27TS20 No Horiz drive
> This set comes on and has B+ to the output but no horiz drive to the
output from IC301
> Do not have the manual and cannot seem to find a data sheet on IC301 to
check B+ to the horiz drive. I have replaced the coupling cap (.47uf 50v)
between the base of horiz drive transistor and the IC 301 but It has no
drive from the chip. any ideas or maybe a print of IC301 ( CXA1013AS)
