Philips 24CE4570 Chassis 2B
"SK" schreef in bericht ... I have an old Philips 24" TV (Model 24CE4570, Chassis 2B). If the problem is with the battery, can someone tell me if the battery is the yellow thing with OIC writen on it in this picture as I can't seem to remove it because it's soildered on to the PCB board. http://snipurl.com/6ra6 Also where is the most likely place to get a replacement from in the UK. Maplins perhaps? Thanks for any help. 99% it causes the problem. It's a ni-cad battery 1.2V / 90mAH. If you don't have it or can't get it take a 1.5 V penlite ni-cad and sand the connections, now you can solder him with wires and place it somewhere isolated with not to long wires with a ty-rap. Mostly in my experience the suddenly starved a dead. After replacing you must memorize the stations again and also the settings for sound and vision. To memorize the sound and vision there are a few methodes depending the software and the chassis. Press memory open, PP (green button), close memory Or close memory, PP (green button). Good luck Peter |

"SK" wrote in message ... I have an old Philips 24" TV (Model 24CE4570, Chassis 2B). It had been working fine until recently when all of a sudden it stoped remembering it's settings when switched off. It now forgets all the settings for the channels, colour and sound and requires a re-tune each time the set is turned on again. It is fine if left on standby. Having done a bit of googling it appears to be a problem with the backup battery which seems to be a common fault amongst Philips TV's from this era. Would this be a correct assumption bearing in mind that it has stopped suddenly rather than over a period of time?

The battery is in the TV now so what would be the best way to charge it, leave the TV ON or in Standby mode? |

The battery is in the TV now so what would be the best way to charge it, leave the TV ON or in Standby mode? After replacement put it on or in standby (doesn't matter) for 5 minutes, switch off the ktv and measure the voltage over the nicad. It must be 1.2 Volts. If so, switch on and you have to search a channel and put it in memoryplace 1 Also adjust the sound and vision with the local keyboard or the remote and store it in the personal preference memory After switch off and on again the channel and sound and vision stetting must be held in memory. For longer memorizing let the ktv set on or in standby for about 4 hours and the next day use it as normal. Now the set functions must be ok. Greetings PP |

Be sure to clear up any leakage from the previous battery. If the old
one did leak then this could corrupt the circuit board and result in poor contact or the new one not charging. (In both the ones I've done the battery had leaked.) New ones took several hours to charge so leave the set on Ben |
