GREAT TOOL ! 100 watts backs up the lower power common HDepot Wellers...comes along...
 
looking for tips, PP lists a catalytic screen replacement goes between tip and reservoir.
 
anyone know how long the original lasts, how we tell when its going, and if short lived under 'normal' use is the replacement a standard order when buying more tips ?

Sort of a long story, but here goes: We have had 3 LCD TV's with the same issue. It is intermittent, but every day, typically multiple times a day the TV will completely power off. Each of the TV's have been hooked to the same power outlet in the same room. We have had both Charter and ATT as TV providers during the 4 years this has been happening. We have used other power outlets (via extension cords) and even had an electrician check the power on the circuit to make sure it isn't a power issue. Currently the charter TV which is on the same outlet will stay powered and only the TV shuts off. Again this has happened to 3 different TV's so we just can't figure out what it going on. Any ideas would be amazing! Thanks everyone

Yeah, you can now use it as a taser.

No danger of electric shock. The problem is that the phone calls and
worse yet, the pictures, can leak out and mess up your pocket.

Hey, what if nobody told them. Is that their fault ?
 
Explain and teach and ADD something to humanity rather than taking away from it.
 
Ignorance is not a sin until it is willful. When you see that go to town.
 
Maybe nobody ever told them the shit you think they should know. Is that their fault ?

I am hearing impaired, so I use Close Captioning a lot.
 
I have a DVR/DVD recorder that I use for recording OTA programs to watch later.
 
When the signal from the DVR, is sent to the TV using composite video, I can enable CC on the TV and get the CC content for the program that I am watching.
 
If the signal is sent to the TV using HDMI, there is no CC.
 
Is there anyway to make this work using HDMI? I would prefer to use HDMI for a better picture from the DVR.
 
Thanks,

My answer is not definitive or conclusive, but I would recommend you check al the menus in the DVR. I know that in NTSC (which is the composite or SVHS) the captions are sent during the vertical interval. You used to be able to see them if you had a vertical hold control. Now it takes either a modification or a scope with dual time base.
 
With HDMI there may be a whole different scheme. It is not sso much the higher resolution that makes me think that, it is possibly other information that maty have crowded it out and now it is sent some other way. Simply not being interlaced would change the scheme of things. Or maybe the DVR generates it instead of the TV, I do not know but it is possible. If so, remember that if you were to copy it the CC would be one the screen in the dubbed recording.
 
So, look at all the menus, if you do not find anything it may be a limitation of the system.
 
Question : Are you simply using the DVR tuner straight off the air ? There is no convertor box ?
 
Another thing you might consider is seeing how good it looks using SVHS/SVIDEO. It does make a difference. Just not going through the COMB filter helps. It might be good enough because not all OTA material is really high resolution. when they split one channel into four, it is not quite the highest, like watching a movie at the theater. Between the line doubler and the enhanced video bandwidth it might look good enough.
