Meet this fault, don't jump in pipe, first broken bank B + power supply circuit of the current limiting resistor R816 Ω / 2 w (5.6), the B + power termination a 100 w bulb, test the B + voltage stability normal (models is different, B + voltage is different also, such as 108 v, 108 v, 115 v, etc.), line flyback capacitance C565, C558, C557 at both ends and a 3000 pf / 2 kv flyback capacitance. He then changed into a quality goods the same manager, on both ends of broken R816 pick an ammeter. Current meter on check, observation, the current by turning moment of more than 280 ma, speed up to 800 ma, quickly shut down, touch pipe hot hot. Due to the large line current, and repeated loss manager. 8Xfservice manual download site

Stay if pipe to cool down, with his hand holding forceps, touch line field scan small signal processing integrated block IC501 (AN5435) 4 feet, the full picture immediately, and a normal black and white images, current also dropped to normal about 280 ma, immediately shut down (process may not be too long, in case of damage of pipe). Time line oscillation phenomenon shows IC5014 foot receive timing capacitor C507 (pf) 3900 or C508 (including 0.0039 F) damage caused by horizontal frequency is too low. Replacement of the same model C507 or C508, troubleshooting. Line output is normal after test tube Q551 b voltage by the failure of... 0.33 V is back to normal... 0.1 V, pipe work is normal.8Xfservice manual download site
