Location of Vfg test point for checking SU/SD boards 1 CONFIDENTIAL 2009 PDP Service Hints: 1. For 7 blinks (floating side error> SU/SD suspect): SU and SD PCBs cannot be isolated in turn (as could be done on older models) since this can lead to other PCBs becoming damaged. Both the SU and SD PCBs must be isolated together from SC PCB and SC50 connector pins shorted out using an insulated croc clip or the dedicated connector jig shown (P/N TZSC09187) 2. See slide below for how to isolate the SU and SD PCBs. The guide also shows how to test the SU or SD pcbs if they are found to be the cause of shut down. 3. For 6 blink problems (energy recovery error> SC suspect): For 2009 HD resolution models: X10 or C10. These models do not allow the disconnection of SC PCB as it may lead to SS PCB damage. For these basic models, if a scan board blink error still exists after carrying out step 1 then a new scan board must be tried. NOTE: FHD 2009 models (S, G, V and Z series) can have the SC PCB totally isolated (unplugged) without the need to try a new one. Identification and Jig introduction for Scan Drive Circuit problem 1. Diagnosis for SC board or SU/ SD board. On '09 PDP models, a service jig (TZSC09187) can be used to identify if SC or SU/ SD board is defective. The procedure is as follows. SC JIG TZSC09187) 1) Disconnect SU and SD board from SC board. (*1) 2) Connect a Jig (TZSA09187) to the connector "SC50" on SC board. (*2) 3) Check the front LED condition after Power on. (*3) SC50 LED Condition Defective PCB Lit (Normal) SU or SD board are defective Blinking SC board is defective (*1) There is no need to disconnect FPCs (panel's flex
