I got this one for my Dad 2 1/2 years ago more than $4000 , now it has only sound but no picture. As my Dad said, he heard something popup in it then no picture, sound is still good, can you help me fix it, because if it cost me to much for fix it I will throw it away. Thanks for all your help.
when you're behind the set, there is a large, rectangular power supply board in the upper middle of the set. On this board, the two transistors mounted on a heatsink in the upper left corner would be short circuited. Normally you can also see some SMD resistors which are blown, or see a little burst and some soot on the grey kit dots which are used in that area.
After the panel itself, this is the top repair for this model.
The complete board has to be replaced, because it's an OEM part and there is no schematics or partlist. In Holland it's sold for aproximately EUR 325,- incl. VAT.
Replacing is simple, only the flatcable must be handled with normal care. There are no adjustments necessary when replacing this board, in contradiction to other models.
I suppose your set has been brought in from England, because of the suffix -U in the model number. Your user profile tells a current location ŽUSAŽ.
The partnumber I mentioned is the reference this PSU is known in the Sony parts master file and must be the same in Europe and in USA.
Every distributor of Sony parts could use this partnumber as reference.
Maybe you can contact you local Sony authorized workshop for assistance.
