philips matchline television
Hi,
I got this old Philips matchline TV set from someone. It works fins for about 5 minutes and then it switches off, that is: the power supply switches off; the lights in the front of the TV start blinking asnd the rest is dead. I opened it up hoping to find something in the high voltage section where I suppose the fault is. There is this rectangular ceramic housed resistor which becomes quite hot. When I keep it wet with a bit of spit, the TV keeps functioning :-) Unti lI run out of spit. Does someone maybe have a valuable suggestion for what may be wrong based on thsi poor discriotion of the problem ? (I'm hoping it's a quite common problem, that's why I dare take the chance of asking). For the real professionals: the type number of the set is 28ML8605/00B. Thanks for any suggestion ! Fred. |

philips matchline television
Hi Fred,
Have you checked the solderings first, due to bad conctacts on it, you can get the same problems. Check the soldering of the right pcb (seen from the backside), resolder the high voltage transformer and the other small transformers first. Most of the e few minutes after problems will be gone after this. Greetings Peter "FreJa" schreef in bericht ... Hi, I got this old Philips matchline TV set from someone.
