User manual FUNAI LT850-M22 SERVICE MANUAL

[. . . ] SERVICE MANUAL This Service Manual is for the LT850-M22 (A0C70EP) / LT851-M22 (A0C71EP) model. For the LT850-M22 (A0C70EP) / LT851-M22 (A0C71EP) model, the letter (A0C70EP) / (A0C71EP) is printed on the Serial Number Label on the back of the unit. Label "A0C70EP" "A0C71EP" 22 COLOR LCD TELEVISION LT850-M22 / LT851-M22 22 COLOR LCD TELEVISION LT850-M22 / LT851-M22 TABLE OF CONTENTS Specifications . 15-1 The LCD panel is manufactured to provide many years of useful life. [. . . ] Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit. If Main Fuse (F601) is blown , check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail. NOTE: The voltage for parts in hot circuit is measured using hot GND as a common terminal. For continued protection against fire hazard, replace only with the same type fuse.

Also, in order to have the ability to increase the input slowly, when troubleshooting this type of power supply circuit, a variable isolation transformer is required. CAUTION !Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit. If Main Fuse (F601) is blown , check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail. NOTE: The voltage for parts in hot circuit is measured using hot GND as a common terminal.
