Tv phillips model 20pt4331 / 55r without audio with black strip on scr
Thanks for answering friend nicomena2015, this tv uses 2 bugles of 16 ohms, the other one is good and with the maximum volume it does not emit any noise, I will make the measurements and replacements and comment on the results
I tell you my progress, I replaced the capacitors you mentioned and the black strip at the top of the image was removed, in the same way the audio came out with good volume and replace the damaged bugle with another one but I only have one detail left, although the detail Image is seen at the top of the screen 3 fine lines are observed very close to each other of red, green and blue colors at the top of the screen, my question is what is it and what tests could I do?
change the C2460 of 56nf ... if you have already solved the fault do not forget to value my contributions ... from me (congratulations) ... and comment solution ... greetings!
Thanks friend nicomena2015, if the main fault is pactically solved, I will change the capacitor you tell me and of course I will value your patience. Greetings!!
Friend nicomena2015 I got a phillips chassis and change the filter you mention in this case for one of 0.082jx 250 volts, then when you turned on the TV, at first the lines of delay on white background came out, at 2 seconds the image of the channel and 5 seconds later TV turned off, my question is this filter is a good substitute? why does the tv turn off?
if it is the same plate it does not turn off before changing the C2460 ... according to your comments ... the TV turned on well only with those colored lines ... I do not see xq, it should turn off x change the C2460 ... unless, such a capacitor is damaged or short-cut ... take it back and test if it stays on as before ... or maybe you have removed something in the circuit ... look closely ... try with another capacitor that is in good condition ...
Indeed, the spare capacitor was bad, change for a new one and the lines disappeared, I consider the post solved, Thank you for your valuable collaboration.
Hello colleague: I'm glad to know that, you have solved the fault ... again "congratulations" ... do not forget to value the contribution received ...
Cheers!!
