Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Sony | KV32S10 | Relay clicks continuously at switch on | Replace Flyback | ||
Sony | KVM2511 AE1 | Can not switch on the set, supply ok | Suspect L807 of o/c Pt no. 140750400 also check R008 and C017 | ||
Sony | KV27EXR25 | No raster, the set will click on but no high voltage | Replaced IC651 on the power board type STRS6301 Note: Use an original STRS6301, not an STRS6301A unless the 6301A comes from SONY This part does run very hot | ||
Sony | KVA2542 | Fault not limited to this model. Turning itself to standby, mostly when warm. Flashing error code on LED's. | Dry joint on IC TDA8179 under metal shield. May need replacing with STV9379. May also need to alter picture geometry settings HSIZE, HPOS, VSIZE, VPOS in service menu | ||
Sony | FE-1 | Set shuts down shortly after start up with standby led flashing 2, 4 or 5 times | Check / replace chip resistors R543 47Kohms and R541, R573 and R575 all 100Kohms | ||
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 | ||
Sony | 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 4.7ohms, 5%, 0.25w as a precaution | ||
Sony | 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 | ||
Sony | KV2020 | No Sound | Replace sound i.c TBA120U | ||
Sony | FE-1 | No picture or dark picture | Check R516 56Kohms, 0.5w or R517 27Kohms, 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 | ||
Sony | 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 |
