Got this 21" set with chassis BEKO 12.7 . came in with duff line transformer (LOPTX) - charred and emitted smoke when powered up. reference number on its side: TLF158E-06C 3817 A
checked the HR diemen ref and the 3817 corresponds to HR7503.
Got it, fitted it, but the set didn't start up from standby. B+ gets to the LOPTX but nothing at the HOT collector- something going amiss somewhere. have checked for shorts on the ps outputs and other lines off the LOPTX (vertical etc) - seem ok.
Don't know if the HR ref was the correct one ( but beko is listed under hr7503) or the replacement is simply duff. perhaps some kind soul could check which is the reference number of the LOPTX on this chassis; on my schematic nothing is printed. Then I can double check the HR list
cheers
