Sony KVM1400
Will not power up, red LED blinks twiceReplace ICP fuse in HT line PS801 N15, 600mA mounted adjacent to pin 7 of LOPT
Panasonic NV370E
Display shows dew sensor at irregular intervals and different circumstances causing the video to go in standby modeBouncing effect of power switch on timer board. Only one section of this double pole switch is used. Add a 1nF capacitor in parallel to this switch and use the second section as well
Hitachi C2864TN
Psu in slow trip. 630mA fuse on E/W panel blownTop E/W diode leaky D704 BY228
Orion 5130-2RC
Picture was black and white, twisted, sound came and wentIf switched on for a long time the picture improved but was still not OK. Capacitor C210 in the IF section had failed. Replaced and all OK!
Goodmans 1410 TX805
DeadOne of the three series connected 68Kohms resistors was open-circuit. RP44 is rated at only 0.25w. It hides beneath two large green power resistors. The other two 68Kohm resistors are rated at 0.5W. We replaced them all with 1W resistors. Soak tested ok

Main fuse blastedReplace the STR50115
Philips GR1AX GR1AX
Will not start up from coldCheck if 95v line increases to over 100v when TR7628 BF423 is chilled. If so, replace D6629 BZX79-C12 and re-check 95v/re-adjust R3625. May also be worthwhile replacing TR7628 and C2629 as a precaution!!
