Beko28426NDSProblem is ticking BU508df(LOPTr) and flashover on EHTpiller from LOPTX. Can i be informed of any other associated components that would need replacing. The BU508 has destroyed twice. you need to replace the lopt and transistor ,then check the line drive frequency-there is a fault which increases the line frequency and there are certain mods which may need to be carried out. you should have a working set one the lopt and line transistor has been replaced.Try the wimtv site for mor info if you have more problems12-12-05
