Question about Mitsubishi Wd-57731 57-inch 1080p Dlp Hdtv
I was having the power light blink a bunch of times then turn off.. i googled the problem and a few suggestions said to change out the capacitors located out on the DM board.. i located them and replaced them with 4 1000uf/35 capacitors. i then hooked everything up and tried to turn the tv back on.. still green flashing power light. only now im hearing a small clicking sound coming from the board that the power cord hooks into.. not sure where its exactly coming from but my guess is it has something to do with it.anyone ever have this issue.. any suggestions would be appreciated!!

Please study the procedure at the following address.....
use 1000mf 25v or 35v 105 degree capacitors to replace
original four 1000mf 16v..............if new ones are a little
too high,just lay them over on board........
Look it over..........let me know......................T.

The most common failure are the two convergence integrated circuits part # 267P173010. The two pico fuses may be open as well, which come from the power supply and provide +24 volts and -24 volts.

If the indicator stays on then you may have an DM PCB problem and to correct this do the the folowing:
SYMPTOM: Power LED does not stop blinking after plug in.
CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).
The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.
