FE-1
|
Set shuts down shortly after start up with standby led flashing 2, 4 or 5 times | Check / replace chip resistors r543 47kΩ and r541, r573 and r575 all 100kΩ | ||
| SONY |
FE-1
|
Changes channel or volume adjusts by itself | Check s900/1/2 on pcb h1, alternatively this could be due to failure of ic005 cd4052bcm-fl63 on pcb a | ||

FE-1
|
No power no standby power supply op | Ic609 top209 was faulty, also checked c640 47uf, 25v, d631 mtzj-12b, d628 p6ke200, d629 uf4005pkg23 and r627 4.7Ω, 5%, 0.25w as a precaution | ||

KV20TR22
|
Intermittent reception on vhf / uhf | Resolder tuner especially the around the tuner i.c | ||
| SONY |
BE3D
|
Picture too big, maybe strange colors, shuts down after a few seconds | Check for shorts in ic606 9v voltage reg | ||
| SONY |
BE1
|
Loss of sound when set was cold / extremely distorted sound when cold after set was turned on | Sound recovered within a few minutes of turn-on and was then normal. check the electrolytic capacitors and diode near to the audio output ic heatsink. 100% rectification was achieved by replacing the diode and small value electrolytics in the immediate area of this ic's heatsink | ||

KV2020
|
No sound | Replace sound i.c tba120u | ||
| SONY |
FE-1
|
No picture or dark picture | Check r516 56kΩ, 0.5w or r517 27kΩ, 0.25w for high resistance or o/c | ||
| SONY |
FE-1
|
Excessive width | This was due to q532 2sk2251-01 being s/c, it is advisable to also check other ew circuit components as a precaution | ||
| SONY |
KVM1400
|
Will not power up, red led blinks twice | Replace icp fuse in ht line ps801 n15, 600ma mounted adjacent to pin 7 of lopt | ||
| SONY |
KV2165MT
|
Main fuse blasted | Replace the str50115 | ||
| SONY |
FE-1
|
Band of interference down left of screen on dark scenes | This was cured by adding a 1000pf, 2kv capacitor part no. 1-161-731-81 in parallel with d539 in the ew diode modulator circuit | ||
| SONY |
FE-1
|
Loss of one colour with teletext and on-screen displays | Check the appropriate 2sc2412k transistor q007 green, q008 blue or q009 red | ||
| SONY |
KV28WS2U
|
No sound, speakers pop out if volume is raised from zero. audio output from dolby a1 board at +5v dc. | Lightning damage to this set and connected vcr. centre/surround amplifier ic shorted blowing ic protector to its negative rail. both amplifier ics replaced as a precaution. no damage to dolby a1 board | ||

KV-25M80 BG-2
|
Dead | 5v supply transformer short | ||
| SONY |
KVS3432U AE2
|
Front led flashing 13 times, ht at first came on at 139v then went to 75v going off etc shuting back down in protection mode | Found r854 open circuit on -15 volt line off line output transformer | ||
| SONY |
KV2184
|
Main fuse blasted | Replace the str50115, also replace the mains electrolytic capacitor | ||
| SONY |
FE-1
|
No teltext just p100 | This problem was caused by q405 2sc2412k being s/c | ||
| SONY |
FE-1
|
No power although relay operates main p.s.u inoperative | Check ic606 strf6654 for failure, also check resistors r659 0.33Ω,3w, r660 0.39Ω,3w, fusible resistor r603 0.1Ω,0.5w and capacitor c625 100uf,25v | ||

KX27PSI
|
Almost totally dead. no video or audio whatsoever. only the clicking sound of two power relays when the set is turned on, and conversely at power down. the green/red lights on the front panel do appear. repeated failure every 2-3 years. why ? | An insight into what tv engineers did, after speaking to sony uk: a 0.47k resistor replaces l656 in line to q651 b. b 0.33Ω resistor added between l650 and q651 e. a resistor also replaces l657. still lasted only 2 years. any better ideas ? |
