Has anyone replaced a power supply in a 542-B11 recently?
My set recently died, and I ordered a replacement power supply from CCE Parts.
Unfortunately, I could not reuse the existing wiring harness as the sockets on the new power supply are slightly different and the old connectors will not fit.
Fortunately, the new power supply comes with a new wiring harness, but I ran into a problem. The connector to one of the back-light assemblies is different; it is too large (13 pin connector, but 12 pin socket), and will not plug in.
On both sides, the board is marked pins 1-5 is +24v, pins 6-10 is ground, pin 11 ts BRI, and pin 12 is on/off.
In the old wiring harness, both sides had no wire at pin 5.
The new wiring harness on one side has all 12 wires present, and the other side (13 pin connector) has 12 wires (5 +24v, 5 grounds, an empty pin, then the remaining two).
Both the old and new power supplies have the same model number FSP271-4F02 Rev 10.
I called CCE parts and they verified I ordered the correct part. They even pulled another power supply from stock and checked the cable ends; one was 12 pin and the other was 13 pin, same as the one they shipped me. My TV has 12 pin sockets on both sides.
Would I be safe in re-pinning the connectors to match the original? Should I have a +24v wire on pin 5?
Anyone run into this problem with their 542-B11?
This TV had an excellent picture, and I hope I can repair it.
Can anyone help?
