Hi all.
I have a problem, ok my TV a Sony flat screen trinitron, bit dated but works, thats when its on, i dont do much TV stuff, but when its turned of and power removed it plays up and takes several or more attempts to fire up, before this started i noticed what i would call a high tension twang type noise on powering up, i had a feeling it might escalate and it has.
Its on now, but turn of and its a git to get it back on, i understand tv theory and am comfortable working on high tension circuits, i think it might be a relay maybe latching thats at fault, as when its on its fine, and when it does fire up now after multiple attempts there is no twang noise, does or can any one give me any ideas, in addition to what ive put above, ideas appreciated, it was second user when i got it, so it about 4 years or a bit more old, there is no picture, or other peripheral problem, thanks for looking in. Dave.
