Does this picture apear to be right size?
or is it just a little too big for the screen
this tv had a bulletin on resistors in the power supply that had to be changed that control power supply regulation
its not a DIY repair
but it is very easy for a skilled expereinced tech and repair should be 100 dollars or less
What is the Bulletin # ?. I am experienced enough to change the resistors myself.
Give me a phone number to call for the Bulletin # XXXXX replace Resistors in the Power Supply please.
If the picture is too wide and/or the unit will shut down check the B+ voltage. If it is much >144V replace the 3 resistors on the power supply pcb as per service bulletin #ASC20060801001.
Part Number Part Location Part Description
2004-002015 R818 140KΩ, 1/2W
2004-002018 RS807 220KΩ, 1/2W
2004-001894 RS802 237KΩ, 1/2W
usually R818 will go way off value
these are in the SMPS
on the left side of the board
Thanks for using JA IF you have any other questions please ask
Made the Modifications and changed the three resistors per service bulletin and the unit does not turn on at all now.
Will undo these changes and replace the two resistors taken out R818 and R807, which were 140 ohms, and 330 ohms respectivly.
I doubt the Service Bulletin ASC20060801001 is for this model TV.
