Can I leave TV power on to avoid long warm-up?
My 42" Samsung TV is ageing but still produces a good picture. However it currently takes 5-7 minutes to warm up. During this time the power light flashes 5 times every 20 or so seconds. When it is about to come on there is a click, like maybe a contact is being closed. Moreover, every once in a while, the new picture appears severely pixilated and I need to turn it off for a few seconds and restart it.
I've taken to leaving the TV on if I know I'll be back in an hour or so. My question is whether it is harmful to leave it on permanently. I do turn off the cable box but the set displays a "no signal" box which jumps around to prevent burn-in.
Update (Sorry I've been slow to get back). I found a replacement board http://www.samsungparts.com/Products/Par... for $140, which seems to me to be easier and safer than doing amateur electronics. (Though I once put together a Heathkit color tv kit with only one small fire. It worked.) I do appreciate your help and please let me know if replacing the board is a bad idea.
Is this a good question?
