Question about Samsung PS42D4SX 42 in. EDTV-Ready Plasma Television
Screen is blank, have sound, power led flashes 4 times. repairer thinks it might be power supply (not sure) but parts are hard to find.
Is this easy to test and how?
Where can I get parts?
Many of the parts in these sets are proprietory. The manufacture reps generaly change the complete board to service the sets.
The can be failed and you change them, but you would have to also find the cause of the failure. If not, when you apply the power back again, the new parts will fail again!

Vladislav fixed his TV already by replacing some defective capacitors in the power supply.
The locations of the defective capacitors are C523 and C524. The value is 0.22uF/400VDC or can use 0.22uF/600VDC Polyester coated.

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.
