The set reverts to standby intermittently Set ht control had invisible dry joints
HITACHI C2146TN
Dead / int, led lit Check the 5v regulator ic952, 8v regulator ic951, standby regulator ic950 and the field output chip ta8427k or for dry joints on the regulators
HITACHI C1714T
Frame collapse, causing set to go dead, also can cause the regulator transistor, to go s/c. but12af. h.t. unstable Check r951 39k goes high, in this case 65k, causing ht to go high
HITACHI C2846TN 311
Frame collapse or dotted line Check and replace frame ic ta8427k or check r710 for open circuit, also check for possible dry joints on d601

HITACHI C2133TN NOKIA STEREO PLUS
Very strong red content in the picture, sometimes the fault would clear with the strong red content fading until the correct greyscale was achieved After much searching around i found the problem. tsound was a very small crack in the solder at rh23, this is a 2k4 surface mounted resistor located at the back of the tube base. resoldering both sides of it cured the fault
