TV Repair Questions? Ask a TV Technician for Answers ASAP
Sorry for delay, the model number you sent is not coming up could you please re-check?
OK if you try another input like a DVD player does it do the same thing?do you have another input to try?
And is it behaving the same way?intermittent sound?
I am assuming it is, in that case you do have a problem with the main-board inside the set, the sound amp is mounted on the mainboard and its this board that will need to be replaced is this something you think you can do yourself?just to clarify we are talking about a plug in board no soldering no setting up
Let me know please
No setting the mainboard does it all, you did trace the speaker wires back to the mainboard?it doesnt go to a sub board of any kind?
Is it the exact same symptoms as the original board?
It is possible there may be a common issue, I do not know of it however and replacing parts on these boards is not recommended due to the liability for error, you should just get the board swapped again indicating they have sent a faulty board this is what I would do ,it can after all only be that board
Where did you sit your city and guilds in TV ?I was kind of aware that this had been replaced many moons ago by a electronics servicing cert?poss 20 plus years ago
I sat the 5 year course (2 days a week) 222 course this covered TV\ electronics\ Radio \and tape recording all now sadly defunct well except for the good grounding in electronics which was\is the keystone of it all TV meaning the CRT sets
Not sure if I agree with you on that but yes let me know
I have already provided it, you will need to get another main-board nothing else on there does anything with the sound
Please I would be grateful if you could you rate the information or answer positively with the rating bar of stars at the top of the page, rating me positively enables me to receive payment from the site thank you, ***** ***** question is open for 30 days.
There is no other solution, you need to send the board back that you got , this is not unusual 1 in every 5 boards I get is bad, the boards are not new but pulled from damaged screen sets
The only oddity is its showing the exact same issue UNLESS those LED strips you fitted are somehow arcing?have you thought of that?that will cause breakthrough on the sound
Actually that seems more plausible, you should go over what you did
Nothing else that anyone can tell you on this particularly if you may have caused the issue yourself
OK yes I will be interested to know thanks
