I found PD1146B is the signal board part # 23788628x $155.08 list $198.82. 4 in stock at Toshiba I can't tell if the MVPU41A comes with, but I don't see that number listed so it possibly comes with the signal board. I have seen the main board have tiny cracks next to the connectors from plugging in or removing the DCU on some units. Possibly your problem!? good luck Robert tvservice@xxxxxxxxxxxxx H & H Electronics Inc ----- Original Message ----- From: "markbrock" <markbrock@xxxxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Wednesday, April 27, 2005 8:30 AM Subject: [TechAssist] Re: TOSHIBA 57HX83 tac 0355 > Robert, I think the board number is PD1146A, tristate says Toshiba doesn't > have it ??
