Bush 28" ws6673ntx White line picture collapse?

Field collapse is not diy repairable fault.

The cause is usually dry soldered joints to the field output IC and/or leaky electrolytic capacitors or diodes in the field output circuit causing it to operate incorrectly/overheat.

Although it requires an engineer, the repair costs for field output faults are usually not too expensive.
