Goldstar | KBV-9012E TV/VCR Combo | White 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 |

C820 IS NOT the smoothing cap for +180V. | 14-09-04 |
