Its usually easier going though the back of the tv. Use a vacume also, you want to draw out all the comtaminats not blow them in with canned air. Dont wipe the lenzes of the crt tubes. Beware the tv holds charge even when unplugged. Hope this helps,.

Need to take apart a Toshiba 57H83 for cleaning

This is fairly easy to do.

You will work from the back of the tv.

1) Unplug the tv and wait a ten minutes for components to discharge.
2) Take the back panel off which is the brown pressboard with all the holes. Probably about 12 screws for that tv.
3) Take the back top plastic shround off if you want to clean the mirror. There are about 15 screws around the perimeter of the shroud, and maybe two in the back.
4) gently lift the shroud off the tv, it will have the mirror attached to the back of it so be gentle and careful.
5) lay the shroud on the floor so you can clean the mirror with window cleaner or non-streaking solution.

6) with the shroud off you should be able to see the tops of the CRT lenses covered in dust. Clean those gently. Do not bump them or turn the lens in any way otherwise you may need to do some re-alignment and/or re-focus of the CRTs.

7) DO NOT USE window cleaner on the back of the screen or front of the screen. You should get screen cleaner solution for this specifically. It might be best to just vacuum the spider webs off the screen and not clean it if you don't have the screen cleaner handy.

To clean the dust off the circuit boards, here is a tip:

With a clean soft paintbrush and a shop vac, or house vacuum, use the paintbrush and lightly brush around the components and on the circuit board. Have the vacuum hose right next to the paintbrush so it sucks up the dust as you stir it up. BE GENTLE on the components.

Stay away from the CRT necks and do not use your fingers. Remember the CRTs can still be carrying a good electrical charge, so best to avoid them.

Re-assemble the tv after everything has been cleaned. Figure it will take about 45 minutes if you haven't done it before.

I would suggest to leave your directtv hd/dvr box connected the way It is.
The HD Colorstream 1input on your TV should work just fine.
This TV does not have an HDMI input but you can buy an adapter and connect to DVI/HDCP IN and that might be able to get 1080i video resolution on your TV.

Toshiba 57H83 and no longer get any sound. Any

Most often No Sound with Toshiba 57H83 is:

1. TV has a Sound on-off switch on the input panel at the rear of the TV. Very hard to see, black on black. Used to turn off speakers if you use a separate or external sound system for speakers. Usually gets moved while connecting hd cables or dusting and vacuuming in cramped space at the rear of the TV.

2. Someone accidentally changed Sound settings with remote to CC (closed caption) or SAP. Turn off in sound menu and save preference.

3. Sound input plugs from external cable or sat box unhooked or wrong input.

Toshiba 57H83 no sound fault is not common. If you still have no sound, get local service.

Or troubleshoot yourself to determine if Tuner, IF, processing, sound demod, switching or sound output circuit is smoked. Then make an installation plan.

How do I dust inside the screen of a Rear projection TV?

Unplug tv first Usually you can pop the front screen off the set. There may be two hidden catches depending on the model. You may want to use two people for this. Once the screen is off removed the spider web and clean the back mirror with some windex, don't clean the inside of screen with any cleaner. Replace carefully the screen making sure it clicks back correctly

Hitachi 51UWX20B spider web like lines help

I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck

I had a similar problem. Mine was on the left side pf the screen. The service guy removed the front to find an adhesive strip running north to south. The glue had heated up and it did not adhear to the plastic therfore, it was hanging down and lamp light projected it on the tv. He pulled it off both side and there was no more lines. He also commented that spiders are a big problem too.
