Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Samsung | CB5035Z | Stuck in osd mode, no functions | Change the eprom, check that the earthing of the green cable running from tuner is OK | ||
Salora | M | Procedure to enter service mode | Press P then * then 0/AV then # then >M * and # change function Vol+ and Vol- change value >M store current value TV exit service mode 1..7 and . bytes option | ||
Philips | 27CE4599-33R 2A | No sound, with sound at maximum you can hear a weak noise | Change IC7102 U2830B if found, if not U2829B, this IC is located on the sound demod pcb | ||
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 | ||
Philips | VR723 LUCY | Power supply LSM-45 would not start up after power failure | Cooling down of the machine during the power outtage triggered the problem: inside the supply module excessive heat is present that causes components to age rapidly, especially those that are located close to the heatsink. Replaced cap. 2116 100nF, 400V | ||
Philips | VR722 LUCY | LSM-45 power supply faulty after power failure | Replaced elco 2112 100µF, 385V and capacitor 2116 100nF, 400V. See also my tip about the philips VR-723 Cooling down during power outtage. Cheers | ||
Aiko / Perdio | 512 | Excessive brightness with flybacks | Check capacitor C120 2uF, 250V in first anode supply | ||
Toshiba | 217D98 | Severe field distortion | Check capacitor C317 2.2uF, 50V in linearity feedback circuit | ||
Mitsubishi | CT29B2STX | Line output transistor s/c, repeated failure | Replace the four caps in the power supply C905 470uF, 35V, C906 470uF, 50V, C909 2.2uF, 50V and C920 100uF, 25V also note transistor varies with different size c.r.t. | ||
Zenith | D32D51 | Reddish picture | Replaced Transistor Q2005 Type 2N3906 shorted | ||
Hinari | CDTV2 | Power supply fault, clicking noise, nothing else | Check C629 100uF, 25v for o/c | ||
Hitachi | VT530E etc | Playback picture freezes repeatedly when warm / capstan motor overhaul | This symptom is usually due to contamination of the capstan motor bearing which can in turn lead to overheating of the drive chip, the problem can often be remedied by dismantalling the motor and thoroughly cleaning the bearing then lightly lubricating with a suitable light oil before reassembly | ||
Goldstar | CIT-9322 | Volume down control on the set will not work | Everything else worked fine on this rather old model except the volume down control i didn't have the handset to see if this was also the case via the remote. The cure was to replace the micro IC1 which was an M491BB1 | ||
Sharp | 66FW53 widescreen DA-100 , 50 and 100Hz series | E/W fault | Coil L603 part num RCILP0286BMZZ had severely burnt up and Q506 E/W driver 2SD2391 Part num RH-TX0151BMZZ was short circuit. If you have this fault check L604 for invisible dry joints, if you don't you may find you still have an E/W fault when you have replaced the faulty parts | ||
Philips | 14PV163 | Reverts to standby from switch on via TV or Video | No 5v rail because FET MTP3055 o/c. BUZ71 will do nicely | ||
Toshiba | Video Combi Model: VTV1402S | Dead, or intermittent start up. No voltage supply to line driver | Check R504 270k, feed to switching transistor. Goes high or o/c | ||
Sanyo | CBP2580 | The word "factory" in a red box is permanently displayed on screen and sound volume goes from 0% to 50% to 100% | Enter service mode, go down to nvm and press volume plus on remote | ||
Goodmans | 1476TS | Set reverts to standby at switch-on | Check 200v line on tube base for short cct. I901 TDA6103Q goes s/c | ||
Vestel | 6392 | Field collapse no vertical deflection. No sound | Replaced resistor R818 15k, 1w which was o/c. This resistor is the limiter for the 33v tuning voltage | ||
Vestel | 11AK19 | Procedure to enter service mode | Go to installation menu, then press 4,7,2,5 |
