FAQs

What causes the Philips L6.1 chassis to be dead due to EHT lead arcing, and what repair kit is referenced?

The notes attribute the dead condition to EHT lead arcing in LOPTx. The referenced actions include fitting the PSU kit 482231010663 and related LOPTx part 482214010562 (and the indicated LOPTr kit as listed).

How do you address a white screen after the set has been on for a while?

Check and/or replace LOT L5422, as the entry states this as the step for the after-a-while white screen fault.

For the 4-button version, select channel 38 and simultaneously push vol- and vol+ on the TV while pressing OSD on the remote to enter hotel mode. For the 3-button version, select channel 38, then press OSD menu and choose Hotel Mode to activate/deactivate.
