Solution: If a customer complains about a purity problem on a Wega model TV, a simple readjustment of the yoke and/or some minor purity adjustment will resolve the problem. Exchanging of the set is not only unnecessary, but may not resolve the problem. Minor purity adjustments can be made by following these steps: 1- Move the yoke rearward or forward slightly until the best purity is obtained. If this does not cure the problem, continue with steps 2 & 3. 2- Improve the purity by adjusting the purity ring magnets on the CRT neck. 3- If necessary, improve purity even further by adding magnets to the CRT as shown in the service manual section on purity adjustment. Please check and readjust convergence if necessary. MAGNET PART NUMBERS DESCRIPTION PART NUMBER MAGNET, DISK 10MM 1-452-032-00 MAGNET, ROTATABLE DISK, 1-452-094-00 15MM Continued on next page.

Date: February 22, 1999 Purpose: Troubleshooting the KP-53V75 to determine if a CRT/C-Board problem is causing a shutdown condition. Symptom: Technicians are ordering G and A boards in an attempt to repair a "Dead" set (1119) or "Shutdown" symptom. Only to find, when these boards are replaced, the set still does not operate. If a CRT or C-Board shorts, a dead set will result. This procedure will allow a technician to verify if a CRT/C-Board is defective, so that the proper parts can be ordered the first time. Solution: Follow the procedure starting on the next page before replacing parts in the KP-53V75 to repair a dead set.

Unplug the CN501 connector on the G board (contains the 200V DC line) and turn on the set. If the power still does not come on go to step #2. If the power does come on procede with step #1.1 1.1 The purpose of the following procedure is to determine if any of the CRTs are probably damaged or intermittent. Also, a CRT may have arced and caused damage to one or more C-boards. The following steps will allow you to make a judgement as to which CRTs, if any, are damaged or intermittent. 1.2 Keep the CN501 connector unplugged and let the set warm up for 10 minutes. CRT arcing is more likely to occur when the CRTs are warm. 1.3 For each CRT, lightly tap the neck in the area of the electron gun assembly and watch for arcing to occur within the CRT. 1.4 Replace any CRT that is found to arc when you tap it, and also replace all 3 C- boards, even if only one CRT was found to arc. Procede to step #4 before ordering these parts to be sure that the other CRTs do not exhibit phosphor burns. If any of the other CRTs do exhibit phosphor burns be sure to replace them also. 1.5 If no CRTs are found to arc, just replace all 3 C-boards. Procede to step #4 before ordering these parts to be sure that the CRTs do not exhibit phosphor burns. If any of the other CRTs do exhibit phosphor burns be sure to replace them also. TV Products Service Bulletin No. 396 2. Follow these steps if the set does not power on with the CN501 connector removed. Use caution when working in the area of the high-voltage block! 2.1 -Disconnect the blue CRT anode lead and attempt to power the unit on. Repeat as necessary for the green and red CRTs until the unit powers up. If more than one anode lead is disconnected before the set powers up it is possible (although unlikely) that more than one CRT is bad. In this case, reconnect any previously disconnected anode leads other than the last one disconnected and attempt to power on the set. This will allow you to know if more than one CRT is bad. -Replace all CRTs that are found to be defective. Also, replace all 3 C-boards (CB, CG, and CR). Procede to step #4 before ordering these parts to be sure that the other CRTs do not exhibit phosphor burns. If any of the other CRTs do exhibit phosphor burns be sure to replace them also. -If the unit will still not power on procede to Step 3 .1 3.1 -After removing the anode leads it may be necessary to individually remove the C boards to completely isolate the tubes from the rest of the set. Perform this procedure for each tube until the defective CRT is located. If more than one C board has to be disconnected before the set powers up it is possible (although unlikely) that more than one CRT is bad. In this case, reconnect any previously disconnected C boards other than the last one disconnected and attempt to power on the set. This will allow you to know if more than one CRT is bad. 3.2 -Replace all CRTs that are found to be defective. Also, replace all 3 C-boards (CB, CG, and CR). Procede to step #4 before ordering these parts to be sure that the other CRTs do not exhibit phosphor burns. If any of the other CRTs do exhibit phosphor burns be sure to replace them also. TV Products Service Bulletin No. 396 Lens attached Lens Removed 4. The circumstances leading up to the set going into shut down may have had other consequences before the point at which the hard failure occurred. One consequence is that the CRTs may have been overdriven. Therefore, visually inspect all tubes for "burn" lines in the phosphor. If lines are present replace the tube. Aim the light of a flashlight through the lens of each CRT to assist you in checking the CRTs for phosphor burns. If you cannot conclusively determine the condition of the CRTs by this method, then remove the CRT lenses and check them again. ************************************************************************ Sony Service Company Service Bulletin National Technical Services A Division of Sony Electronics Inc.

This problem may be caused by incompatibility between the G-board and H1-board (2 different versions of each board were used in production, but only one part number for each board is available, i.e. one part number for the G-board and one part number for the H1-board). NOTE: AT THE TIME THIS BULLETIN IS BEING ISSUED, ALL HDTV SERVICE IS TO BE PERFORMED ONLY BY SPECIAL DTV AUTHORIZATION THROUGH ZONE OFFICE. IF YOU DO NOT HAVE THIS AUTHORIZATION, YOU WILL NOT RECEIVE PAYMENT FOR SERVICE! When training and service support are completed, this category will be open to all CSV-1 Servicers. Solution: Check the compatibility of the G-board and H1-board beforeplugging in the set.The following instructions and the pictures on the next page allow you to determine if the G-board and H1-board are compatible or not. . If the white wire within the harness looks like that in example 1 or example 2, no further action is needed. . If the white wire within the harness looks like that in example 3 or example 4, you must reverse the mounting of CN4301 on the H1 board. If they are not compatible, make them compatible by removing CN4301 on the H1-board and re-installing it 180. from its original position. It is much easier to remove and re-install CN4301 on the H1-board because it is a single sided board. The G-board is a 2-sided board which makes it much more difficult to remove and re­install CN5901 than it is to remove and re-install CN4301 on the H1 board.
