GoldstarKBV-9012E TV/VCR ComboWhite raster with retrace lines, the set switches off after a while. L901 (in series with +180V supply to RGB trs) oc, the +180V winding of Loptx delivers 300V!! (Di&smooth.Cap OK)Replace C820 10uF/160V cap. Note that +180V supply delivers 300V, while +B and all other voltages are normal. Seems to be a weird LOPTx fault, but it was C820 instead.14-09-04
