Make | Model Ch. | Symptom | Problem Solution | Solution | By: |
---|---|---|---|---|---|
Philips | L6 Series | Vertical lines are not straight when picture is very bright or has white text content | Replace resistor 3420 in the beam current circuit 12k or 15k replaced with an 18k | ||
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 | ||
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 | ||
Philips | 14PV163 | Reverts to standby from switch on via TV or Video | No 5v rail because FET MTP3055 o/c. BUZ71 will do nicely | ||
Philips | 14GR1221 GR1AX | Procedure to enter or exit hotel mode child lock | Put the set on programme 38, press either store and pr - to lock and store and vol - to unlock, or, press pr - and vol + to lock and unlock, press buttons on the set not remote | ||
Philips | GR2.2AA | Dead, no line oscilation, power supply and line output stage are OK | Check / replace C2549 390 or 470nF / 400V and C2545 1n5 or 1n2, 2000v | ||
Philips | GR2.2AA | Does not work after LOT has been changed | Check / change D6561 also change the TDA2579B if there are any sync problems | ||
Philips | GR1AX | Sometimes does not start up from cold, but starts well from power off or standby after a few minutes | After checking all PSU components and consulting many colleagues, casually the tip of my iron touched the body of T2628 BF423 and the set started. After more then 20 attempts, I realised that this transistor became intermittent when cold | ||
Philips | Various | Sound but no picture | Have found on some Philips | s if they are older then 15 years that a 2.7r resistor close to the HT transformer goes open, resulting in sound but no picture | |
Philips | 28PW6005 A10 | Changes to ext 1 when watching tv ok with video input | IC7064 defective, replace it. Philips best nr= 311125054501. price = 48 euro, after replacement the smart settings have been set to 255 read the instruction note for this software!! Code number instruction note = 996500013923 | ||
Philips | CP110 | Vertical ripples on horizontals | Replaced C2633 100µF, 25V | ||
Philips | CP110 | Image appeared after a 5-20 minutes, sound was choppy when changed by the remote | Replaced C2690 100µF, 50V with a 100µF, 63V type, this is located on the small overvolt board in the power supply area | ||
Philips | GR2 | Sound but no picture | Check the LOT cable for short circuit | ||
Philips | 21PT166B/00 AA5 AB | No drive to LOP transistor | Middle sections checked OK. Carefully scoping the TDA8361's Hor. output showed gnd level to be at +0.8v not enough to drive next stage. Change the TDA8361 | ||
Philips | GR2.2AA | Protection circuit operating intermittently | Diode 6592 was found to have leakage causing voltage to protection circuit to be too high, Should be 23 - 28mV | ||
Philips | ANUBIS A | Low Contrast | C2448 47uF, 200v open circuit | ||
Philips | 21PT5505/05 L9.1E | The fault with this tv was a snowy picture no channels tuned in also the permanent 33V supply on pin 9 of the tuner was low at only 1.6V | The first thing i tried was a resistance check between pin 9 and ground. The reading was only 120 Ohms. There's a surface mounted cap right next to pin 9 of the tuner. This was found to be leaky, It's value is 47nF. Also resistor 3442 3.9K was o/c | ||
Philips | 14PT1352/58 L6.1AA | Sound goes off and no remote control functions when heated | This was found to be due to a faulty micro | ||
Philips | CTN-BB | Dead. F1500 o/c, mosfet s/c | Mosfet T7525 shorts, due to smoother cap C2505 goes low capacity. IC7514 TDA4605 must also be replaced |
