Hello. I just copy and past from an article of Nasda. Common Failures In Sony Direct View TV's All, This is a list of the common failures in the Sony Direct View. Most failures are caused by Vertical or Horizontal problems. Sony Switch Mode Power Supply Rebuild Parts AA-1 Chassis Q601 Q602 VDR601 VDR602 VDR603 R607 R644 2SC4834 2SC4834 Varistor Varistor Varistor Fusible 0.1 ohm Fusible 6.8 ohm Sony Part # 8-729-019-51 8-729-019-51 1-807-288-11 1-810-053-11 1-810-053-11 1-202-933-61 1-212-853-61 AA-2 Chassis Q601 Q602 R607 VDR601 2SC4834 2SC4834 Fusible 0.1 ohm Varistor Sony Part # 8-729-019-51 8-729-019-51 1-202-933-61 1-810-974-11 The above parts should be replaced as a set. Always check HOT circuit before repairing power supply. Resolder horizontal drive transformer and do a good visual check in that area. Check Vertical output IC for shorts or signs of overheating Dang goodluck t8872695@xxxxxxxxxxxxx ----- Original Message ----- From: <Hermantvr@xxxxxxxxxxxxx> To: <techassist@xxxxxxxxxxxxx> Sent: Thursday, May 02, 2002 8:51 AM Subject: [TechAssist] Sony KV27S25 Chassis SCC-J71B-A Dead Set > Don't do a lot of Sony...looking for tips.
