| I am doing some work on this same television atm. I believe my problem is related to the power board although I was originally thinking inverter.
Explanation: The service manual shows that the power connector "K6R" between the power board and main board should read as follows. Pins 4,5 - 24v Pins 1,6 - 6v Pin 7 - 5v All of these voltages checked out fine except pins 4,5 which read back infinite on my meter. I then checked the main board side of the same connector and had the same result. All voltages checked fine except for pins 4,5. I then checked the power connector from the power board to the inverter which should read 24v on pins 1,2,3,4, & 5. All of them read infinite. From some posts I read before if you get the correct power up voltages on the power board side (3.5-5vs) but the incorrect power voltages (24v) then you should replace the main power board. If you get the incorrect power voltage readings on the power board side you should check them on the main board side. If incorrect on main board side also then probably bad main board. If you get correct power on volts on main board side, but not power board side then you probably have a bad cable between the main and power board. Anyways I am fixing to order a replacement power board and see if this resolves the problem. |

| can I asked how much was the inverter board, and where you got it. I have the same problem, same model. | |

White squirrel, for my problem, the fix went according to plan with the part from ShopJimmy.com. They seem to be a very good business, from my one-time experience. The 2nd link I gave you does not work now probably because they sold the part (it's price was marked down). They still (as of right now) have another inverter: http://www.shopjimmy.com/backlight-inverter-vit71008-60.htm Good luck. Gerald |

| Hi Minnie,
I didn't know about "partstore". Their prices are good. If they are listing the part as going into a Sanyo DP32746 I'me guessing it will also fit. I was sceptical since the photos I found of part RDENC2548TPZZ look really different from the part I had in the TV. Transformers, circuits and high voltage connectors look different. On the positive side, the power and control connector pinout is a match. Unfortunately, this specific board is missing some metal pads on the circuit board. They help ground the aluminium shield going over the inverter. I'me not sure if this is crucial. The shield is grounded at the other end, so It probably does not matter. So it's probably a replacement and I'me being finicky.  Sorry...
Has anybody tried to repair a Sanyo DP32746 with part RDENC2548TPZZ ? As for part VIT79002.52.... OldIBMer, did the repair went according to plan ? Thanks in advance Hope that helps. Sorry for doubting you Minnie ^-^;; |

| Sorry Minnie but the part number you gave is not the right part number.
RDENC2548TPZZ is the inverter for the DP32648. It will not fit the DP32746. The connector for the neon tubes don't match and the connector for the power and signals don't look like they match. Well they don't match what I had in my TV In the DP32746, directly written on the PCB of the inverter board is this: AUO P/N: 19.26006.110 LOGAH P/N: VIT1008.60 REV:2 I/P: 24Vdc/4.5A, O/P:1170Vac/5mA*16 AUO is the part number for AU Optronics LOGAH is the part number for Logah Technology Corporation lcdpart and electronica-usa have the part |

| RDENC2548TPZZ is the part number, why pay $70 when you can fix it for $20. Fleabay has them also. | |
