Question about Philips 37PF7320A 37 in. HD-Ready LCD Television
When I turn on my 37PF7320A, the green ligh comes on but immediately turns into a one red blinking light followed by four consecutive red blinking lights. I do not know if it is the power supply or other component. If it is the power supply, is there a place where I can find the schematics and instructions on how to change the power supply? My set is out of warranty and the local repair shop wants $650 which is way to much money. Thank you in advance for any assistance yo may provide,
Buy a service contract for the money cant beat it.

Call the manufacture of the TV set to find out who their authorized service is in your area.
These sets are expensive to service. They are serviced by mainly board replacement. There is very little support for component level service.
The boards use high density SMD technology, and is all uPC controled using firmware.
As for your fault, you would have to determine if the power supply is in the protect mode because of a defect on another board, or if the fault is the power supply only. This is usualy done by doing board swapping to find out which boards are defective.
Some of the manufactures will sell the service manuals for their flat panel sets. Not all the schematics will always be complete. The information is mainly for how to replace the boards, and do the factory level calibrations if necessary. You will need the proper calibration and diagnostic tools to do the tests and adjustments as indicated by the service manual.
