"Dead" Emerson (Funai) LCD TV model EWL20S5

[Brad]

Hi,

Regarding Emerson (Funai) LCD TV model EWL20S5 (mfg 03/06):

Symptom: TV won't turn on.

Now that I finally got the SM, I was able to perform tests.

The 5.5V source reads 1.8V. I replaced C635 470/10, which read around
340uf on tester, with a 470/16 105deg., but that didn't fix the problem. I
tested many components and ruled out a heavy load on power supply (SMPS).
Raw B+ is fine. There are other components I have to test, but to save time,
has anyone serviced this model or a similar model with the same symptom?

Thanks in advance, Brad

What is the supply voltage to the regulator< Is the regulator receiving
enough current and voltage to actually perform APD? (As Per Design).

Are the other voltages from the power supply normal per the schematic? Bet
you will find a few more flakey caps in the unit before getting it
operational again. Poor design with mediocre components. IMHO!
