Phillips 27" TV dead.
Model # 27PT5245/37 dead, but sometimes it comes on, at standby, the
set MAY come on, or not, & when it comes on, it will shut down, & back on again over, & over. The secondaries of the SMPS are loaded down. If I unload the SMPS secondaries, I get more stable secondary voltages, but I can't find where the problem is. I can't find anything bad, nor has Phillips found a cure. . Has anyone seen this common problem, & found a solution? Phillips told me to wait a week, & call them again. They are aware of this problem, but have no answers yet. Thanks, Dani. |

I have two of these units, & don't see a chassis #. One has this #
under the model #. S20A8, & the other has 27VM34U, but I can't cross these numbers, even with the Force 32 program. Dani.
