Check the SC board transistors (Q6641-6) for any failed or leaky FETs Order Kit: TZS9EK082 which contains 10 new FETs (B1DFKM000002) Replace the faulty transistors and update the firmware as per attached information below Also check the condition of the soldering on the following FETs after fitting the service kit Q6695, Q6696, Q6648, Q6649, Q6651, Q6652, Q6653, Q6654 In some cases, it has been found that some of the above FETs had no solder on their drain and source connections whilst others may have very poor joints. Notes on Software Updating The attached TI sheet (page 3) covers software updating for the B version sets only. For B versions sets, carry out the firmware update if the item > PDP-FPGA (seen on service mode opening screen) shows less than 47.09 After software update the PDP-FPGA should be 47.09 > see picture of service mode on page 2 For BA version sets The software update should be done using the software file: 42FM10_v4782t1_sddl_CS3.zip Usage instructions for this software are shown on page 2: After update, parameter PDP-FPGA will update to v 47.82 Confidential Page 1 477675856244221SSREV1 The picture below shows this TH42PZ70B model's PDP-FPGA is correct at 47.09 Update instructions for the BA software Confidential Page 2 477675856244221SSREV1 Confidential Page 3 477675856244221SSREV1
