Little help on a SD TV issue please

[wafflebird]

Hey guys,

I have an older (97 manufacture date) Sony 32' tube type TV. I have really enjoyed this set. It is still working, but it seems that it has started building A LOT of static electricity on the screen. Having had this set for years I know that they build up over time and I kind of know its' "Schedule but when cleaning it the other day I got 3 shocks off of it before it "Settled down" and I could clean it. Before I cleaned it I could feel it pulling on the hair on my arms walking several inches in front of it. Is this normal, or the "Normal" sign that it may be starting to die? The picture is still good, I don't use it for audio as I have surround sound in my bedroom, but on that note if the set is on without signal I do hear an audible hum from the set through the speakers when I turn up the volume, this has been the case for a long time. The speakers are the biggest let-down with this set, they kind of suck to be honest. Anyway I DO NOT want to upgrade now as the picture is still great but the issue with the static build-up forces me to ask this question. I know this forum is usually for the new technology but I figured you guys may know the answer.

Thanks in advance.

mine does the same

I've got a similar model to yours purchased around the same time (KD32 something or other I think). The static build up has been like that as long as I can remember. It seems to be related to the humidity, rather than anything in particular with the set. It's never really concerned me, except trying to avoid getting zapped when cleaning the screen. Maybe if you wiped it more often the buildup would not get so bad.

Maybe one of the engineer types on here can explain it. Take care.

I have a Mitsubishi 27" TV that is almost 25 years old. It's nearing the end, it's getting very green, but works fine, and except for the green tint, still has a great pic. It has always had a huge static charge from day one, and my dogs over the years have all been zapped by walking up and sniffing the screen. I've been popped a few times myself over the years. It attacts cat hair and dust big time.

Ah, the joys of owning a Tube TV!

Cool it looks like no cause for alarm

As I said I really am not in the market for a replacement as I am still satisfied with it jut seemed to be a little zappier than it has been before. Don't get me wrong I will eventually upgrade but only when it dies. I bought this just after it was new from a guy moving back to Jersey from South FLorida. Paid a whopping $175.00 for it bacl in 99' for that price I hope it lasts a long long time.

Thanks guys for your responses. They are appreciated.

Static on the crt tube is normal. You will notice this more when the air is dry in the room as it jumps the distance much easier. You have a very high voltage on that tube to get the electron beam to fire onto the face. That is what causing the static build up.

I also say it's humidity. The dryer the air, the more static shocks.

Hemiram, you may be able to bring that old Mitsubishi back to glory by calibrating it in service mode. I have a 29 year old Sanyo 19" TV and its picture was getting a little blue. I put it in service mode (switch on the back) and calibrated it. Now it's like new and still going strong. I can't believe a set that old has a picture that good.

A couple of tips for cleaning the glass on a CRT - don't drag your socks on the carpet when walking up to the set to clean it (bare feet are the best). Use a paper towel and windex, and keep the paper towel between you and the set. I used to get zapped all the time on my 36" Toshiba CRT, but never again. It's simply using you as a ground, and it definitely shocks the crap out of you if you don't tiptoe up to it. One other trick I found out is to only wipe off the glass, and not the plastic housing. If your paper towel touching the plastic, you get zapped.

One other thing to do is vac out the inside around the vent openings in the rear. CRT's get extremely dusty inside. You can use a shop vac in reverse and blow the dust around inside the unit, then use the vacuum to pull the dust out. Beware - after that many years, you're wife may leave you after seeing how dirty your family room is. Same goes with all your electronics. PC's and AVR's should be cleaned every 3-6 months.

I use a swiffer duster. I beat static, and made it work for me Having concrete floors probly helps too. I remember working at Best buy, cleaning the TVs, getting about 60 shocks. I actually said one day "No, these TVs are going to kill me!"

LOL, We already tried that, it's too far gone. I really would like to know how many hours are on that thing, it was on for nearly a decade straight! The red and blue are maxed out now, and if the pic is even slightly tinted towards the green side, it's really bad. I was flipping the channels one morning last week and saw an old "Bonanza" episode. Ben Cartwright's nice white toup...err "hair" was a nice frosty looking green, and a horse was green too. I looked at on my new TV, and it looked totally normal. Some channels have the color messed up anyways, and one local station has a distinct reddish tint to it, the news anchors all appear to be sunburned, on any normal TV, but on the old Mitsu, they are reddish with green highlights, and blonde or white hair is a nice icky green. It's off to goodwill soon for it. That was a great TV, was very expensive at the time, almost $1000, but it's never had to have any repairs. A lot of my friends bought the same model, or the "bluetube" follow up one after seeing it, and none of them has had any problems either, except for old age creeping in. My one friend's TV is getting very blue these days. If Mitsu had still made any smaller Tube TVs, I would
have probably bought one for my mom when she went to assisted living, but the Toshiba has a really nice pic too, and was really cheap too.
