SERVICE BULLETIN PRODUCT: Computer Monitor BULLETIN: Monitor 95-005 MODEL: Samtron SC-428PS SUBJECT: Vertical Deflection Circuit Improvement BACKGROUND: The Samtron 14 inch computer monitor SC-428PS has no vertical deflection after power up due to IC301 (TDA4866) and R301 failing. The problem is likely to occur with the serial number range of A9524002821 to A9538025160. Serial numbers after A9538025160 use a different IC301 (TDA8351). These are not interchangable without making various circuit changes to meet the specifications of the new IC301. SOLUTION: The counter measure to keep the original IC301 (TDA4866) from failing is done by improving the grounding on the monitor. Two ground lugs and two additional ground wires have been added. See the attached page for mounting procedures. PARTS LIST: Below are the parts added to Serial Number Range A9524002821 to A9538025160 Location No. None Part No. 3621200274 Description Wireform UL1015-AWG 22 200 mm BK GND Lug 54 X 18 X 30 X 0.35T None 3112400051 Disclaimer: This information is provided "as is" without warranty of any kind either expressed or implied, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose. REV 9-1 Mounting Procedure - Add a ground lug to point A and point D as in the figure shown below. Take the 200mm wires and route them through the holes labeled E and F in the main pcb as in the diagram below. The holes are located next to the IC301 heatsink. Solder the 200mm wires to the heatsink solder connection located nearest to the routed wire hole. The other end of the 200mm wires are to be soldered to the CRT ground wire as shown below.

REV 9-1 SERVICE BULLETIN PRODUCT: Computer Monitor BULLETIN: Monitor 95-006 MODEL: Samtron SC-428PS SUBJECT: Vertical Circuit Modification BACKGROUND: The vertical output IC301 has been changed from a TDA4866 to a TDA8351. The circuit change was made with serial numbers higher than A95025160. The circuit change was made due to the failure of IC301 in some cases during power up.

REV 12-1 SERVICE BULLETIN PRODUCT: Computer Monitor BULLETIN: MON 97-001 MODEL: CQB4147 SUBJECT: Reduce Q404 Failure Rate Causing No Raster BACKGROUND: Q404 fails when the monitor changes from the DPMS Suspend mode back to Normal operation. Q415 is designed, in the circuit, to cut off horizontal drive to the base of Q404. This is achieved by turning Q415 on in the Suspend mode. In normal operation, Q415 is turned off. There is a delay in turning Q415 off by approximately 15 ms. This will cause an abnormal pulse at the base of Q404, causing damage to the transistor.

The BU2508DF, which had been used prior to this date, has been failing intermittently due to a current surge from the 166 volt B+ line. The current surge is caused mainly from the DPMS off mode recovery. SOLUTION: The circuit has been improved by using a 2SC5149, which has a higher hfe than the originally used BU2508DF.
