jvc : jlc47bc3002 red power light illuminates but tv does not turn on

First row says:  JLC47BC3002

Second  row says::  SERIAL NO: TR1DAM024100535

Third row is a bar code

 

The sticker on the tan board has three rows

First row says:  0500-0405-1340

Second row is: a  bar code

Third row says: 20I333C9P149502

 

On the tan board sticker in the third row, I believe the third character from the left is a capital eye  (  I  ).

 

 

The problem is the  TV all of a sudden decided not to turn on.

 

 First there was no red power light illuminated at the front bottom center of the TV. Then after unplugging it for 30 min, when power cord plugged back into the tv, the power red light illuminated but the tv still would not turn on, neither manually nor with the remote.

 

Removed back of the TV, checked continuity at the white horizontal fuse on the tan board, and meter said it was good.

 

I have no idea what is wrong with it and can only assume it is some sort of power supply problem.  Although that red power light illuminated after removing the cord from the tv for 30 minutes.  So apparently something is getting power.

 

Could you tell me some other items to check in order to try to isolate the problem.

Start by eyeballing all the capacitors to make sure none are starting to expand. All the tops should be perfectly flat or concave, not convex.

Then you can pull the power board and check all the diodes. Best to use the diode function on your multimeter, but the ohmmeter will work if you don't have a diode function.

After that you could check any three terminal semiconductors. If you find nothing and can identify voltage test points, verify they are proper. If not open the line and re-verify. That will tell you if it is the load or the supply.

Other than that, it is a parts jockey operation. However, that can get pricey and it may not be a PCB.
