Make	Model	Symptom	Problem
SONY	KV1746R	Dead, replaced hdt	No raster - no high voltage. servicer confused with hi-volt shut down. virtually lost scope pattern at secondary of horizontal drive transformer.
SONY	KV1722	Part reliability	Sg-613 supplied was installed by service station. partfailed immediately. cones on part are not correct for use in sonytelevision. construction of part is different in appearance to partssupplied by kansas city. code on part: ok-h. -hq comments: in
SONY	KV1545RS	Volume range too limitted, change r102 to 100k	Sound is either too low or too high. customer states thathe thinks the volume should move from low to high in a slower manner,rather than jump from low to high. -hq comments: we can satisfy the customer by changing r102 resistorvalue from 10k to 100k.
SONY	KV1515	No sound	Failure of sound section of ic201 due to static discharge inlow humidity environments. have scrapped volume slider decorative buttonto remove excess silver plating. no help. -hq comments: we are sending you a countermeasure proposal involvingapplicati
SONY	KV1512	Picture distortion	Slight fold-over in center of screen. c406 apparently driedout over the years. located off emitter of abl q4091.
SONY	VTX1000R	No power on	No power-on switching using front panel switch (s802) orremote. customer claimed power would come on intermittently and thatother functions such as video switching, antenna switching would workerratically (this was not verified). when s802 is depressed
SONY	KX2501	No sync, replaced q317 and q318 both should be 2sa1175	Unit had no vertical nor horizontal sync. according toservice manual, q317 sync sep-1 should be 2sc2785 and q318 sync sep-2,should be 2sa1175.
SONY	KV9000	Vertical distortion without video	Vertical collapse under no signal condition. set appeared tohave proper vertical waveforms when receiving off the air broadcast, butwhen no station present only a thin line, this indicated oscillatorfailure or no self-sustaining ability.
SONY	KV5000	No operation with ac	Set would not work on ac. all dc checks which we could thinkwere performed. power supply simply would not start. found waveform 27would appear for just an instant and die away. transformer t606 checkedgood so c611 must be culprit.
SONY	KV3000R	Door jamming	Left side door was found to be inoperative when inspected bydealer. found mounting bolts loose on motor assembly. motor ass'ydrive gear could not engage in door drive track. bold heads had pulledinto soft wood due to shipping and handling jolt.
SONY	KV2648R	No picture, replaced h out transistor	Receiver had no b+ voltages. all voltages and waveforms atprimary side of t602, f board, were all right. resistance check of 135vlines was 200Ω to ground. horizontal output transistor was shorted.
SONY	KV2647R	No vertical sync during changing ch., wrong value r580	Vertical sync loss when changing channels, ok when scenefades out before a commercial.
SONY	KV2645RS	Low brightness, replaced r751	Low brightness, like weak crt.
SONY	KV2645RS	Channel would not lock, adj t205 aft coil	Would not lock on to cable channel #14. cable companyrunning mid-band channels 1.2mhz to 1.9mhz below accepted centerfrequency.
SONY	KV2645RS	Incorrect picture position, add cap	Unable to center picture horizontal. picture off to the leftby 1/2 inch with tap plug into right position. servicer changed yoke,diodes d519, d518 and resistors around center area. i changed severalcapacitors. customer has had this problem from the f
SONY	KV1946R	Picture distortion, r605 open	Insufficient width and no color, b+ 110v not regulating,r605 open.
SONY	KV1945RS	Audio hum, replaced ic102	Hum in sound, follows volume up/down. scoped output ofic102, looks like 60hz hum.
SONY	KV1515	Incorrect tuning operation	Could tune channels 2 to 9 only. vc on this unit cannot gobeyond 15v and band selector switch have no effect, station is tunedregardless of switch position. this problem was caused by a leakys075 causing a high (3.2v) on q104.
SONY	KV1515	Picture distortion	Intermittent vertical collapse, found c508 leaky.
SONY	KV1515	No low vhf	This unit could tune only h. vhf and uhf band. found q103collector to emitter leaky.
