Title: PHILIPS 32PF7521D/10 FAULTY P.S.U
Post by: JAYROD on November 20, 2009,18:39:36

Hi, I have a faulty power supply board, the board used in this chassis is type DPS-188APA [DELTA] which appears to be no longer available. Philips have used various different power boards in this model, and charles hyde list the board as type PLCD 190P1 when i search on there original part finder section under the model number 32PF7521D/10. Can anybody tell me if this alternative board can be used in place of the original board, or maybe somebody might know what the fault is on the board, which is, green led 2 flashes followed by a pause then repeat. No pic or sound. 3.3v ok and all other voltages come up when power is first applied.Fault was intermitant ,fault would appear after approx 1 hour but could run for many hours if back was left off. The service manuals for this tv do not include a schematic for this board type.
 

  Thanks
   Phil.

Sorted !. PLCD190P1 will work as a replacement for the DELTA board. Obtained a used board off ebay £30.  New board £128 from C/HYDE (trade price) !
