Question about Toshiba 57HX83 57" Rear Projection HDTV-Ready Television

Poor focus on right half of screen

I bought this set used from a friend. He had moved it to a different location once and then moved it to my place in an enclosed trailer. I'm thinking it got out of adjustment, something was knocked out of alignment or maybe it was never properly adjusted in the first place.

I have downloaded the service manual. Don't know where I should start. Many terms are foreign to me. I am a master electrician, so I have a knowledge of multimeters and voltages.

I see how to access the service menu with the remote, but the remote hasn't been working well. Sometimes it seems to communicate and other times I can't get any reaction from the set.

There's a start.

Thanks. It was just a matter of adjusting the convergence a little more. I appreciate your indulgence. This is my first experience with rear projection.

I have the same problem. I bet its the convergance chips. They can be replaced by a novice. just with solder, wick and thermal paste. could you possibly send a copy of the service manual pdf to my email? [email protected] I would appreciate it.

Could your problem be convergence and not focus?

Why are my photos out of focus??

Check your settings - try taking sots with the different focus settings and compare. If all photos show some identical signs, you need a fix on your camera. If, for one photo taken with the auto focus settings, look different, you need more practice with your camera.

How do I set my sl620 to selective focus.

Your camera is a point and shoot. This means the camera does auto focus when you want to make a picture. The focus point is in the square in he middle of the screen. The only thing you can change is when you want to make macro pictures. The camera will try to find a focus point within 2 or 3 feet.
Ion some scenes, the focus will differ just a little, like in sports, it will try to be automatic.
The trick every professional photographer uses, is place the focus point on the part, you want to have in focus in your picture. Then press the shutter release button half and wait till the camera is in focus. Then reframe the picture as you want it to be. Then press the button fully. Just as described on page 31 of the manual.

Digital camera won't focus

I see your camera has a focus area. If you have a subject with enough contrasting parts in this area, the focusing should work fine.
You must know that not every subject can be focused on as quick or as good as you would like. If there are little contrasting lines in the subject, or when it is getting dark or there are dark and light parts in the focus area, that don't belong together, every camera can have problems to focus correct. Changing the ISO settings won't change anything for the auto focus.
But special when you try to shoot in almost dark places, you camera will have lots of work to focus and in most cases it won't work at all.

You could try to place an object with light and dark lines, on the same distance as the object you want to picture. Then by pressing the shutter half, when focusing on the object with much contrast, you can look if the camera can focus. If it is in focus, keep the shutter pressed half way down, while moving to the object you want to shoot a picture of. Once you have every thing in the frame as you want it, press the shutter complete.

Emerson 32" LCD LC320EM2F has half a screen now....

That is pretty poor since you are less than 30 days out----Not where you bought it but locate and complain to the company who made it---takes time but they usually can be hassled into an "concession" which is what they do to get rid of people---free repair or a replacement.

To address your problem: all these sets use (each have different names for the part) two boards---in some one drives the top the other the bottom of screen and GUESS what in the others one the left side and the other the right side.

The real hassle may be finding a board but you might want to GOOGLE the model number with parts or boards and see what is listed to get an idea of cost or to see if you can even get the board---if not time to move on and let it go.

The LCD-screen seems to work normal. But when we take a picture (camera-mode normal and record-mode normal) the result is overlighted and misty and full of horizontal lines. In video mode the camera works...

Try to use a different setting like a bright light setting to see if the apeture is closed down further and brings back focus.
the problem is the auto focus which can be going stray and is not setting right.So take time to shoot with the shutter button down to half to allow it to focus and then once the indication of the focus has confirmed to click.
If not contact Sony service for help.

Rectangle in led screen green/ or yellow with exclamation

The camera doesn't have anything to focus on - especially if you're shooting the sky. The auto focus needs something with fairly defined edges to work. Try to focus on the edge of a well defined cloud, or focus on a tree or similar, half depress the shutter to lock the focus, then move re-frame your shot. Alternatively you can use manual focus. Hope that helps

Poor pictre quality

This set has 3 CRT's (picture tubes)
Remove the back bottom cover
Clean the CRT's with windex and a soft cloth.
(Find the Screen/Focus block)----Remove front grill cover and panel which covers the Screen/focus block.
Cover 2 crt's and adjust the focus control for remaining crt---(using the convergence pattern in the menu for the set)
adjust for the best focus.
cover that crt and move on to the next crt using the same procedure.
After setting the focus on all 3 tube's you will have the best focus possible for this set. If picture is still bad, you have bad crt's and the set is junk.
Cost to replace the CRT's is enormous!

Blury Pictures

My Logitech Quickcam for notebooks Deluxe webcam was blurry.

I spent 3 hours surfing the net looking for the answer, only to find a load of vague and technical responses about OS's and other ****. I fiddled about with the focus ring around the lens on my cam, which wouldn't move, so i figured i had an inferior version that had some sort of in-built auto-focus.

Eventually i lost my rag with the poor quality of information i was finding on this issue.

I went downstairs, got my pliers out of my tool bag, and wrenched the lens ring.

It moved.

Camera focused.

Job done.

Voila, no techy **** required.

Green shadows surrounding bright whites

finally a consumer that gives us plenty of info :)
sounds like an overdriven green tube, the only thing you can try is to find the G2/Focus block assembly, either behind front speaker grill or remove back of set and look for a black box approximately 5"X5" , this box will have 6 philips type adjustment screws(plastic) 3 are for focus, do NOT adjust these,
the other 3 are marked "screen" the center screen adjustment screw is for green, turn it VERY slowly counterclockwise while the set is running and pray that your problem dis-appears, be advised that this is a HIGH VOLTAGE device so one hand in your back pocket the other hand turns the screwdriver, if the problem does not go away you have a poor green tube, good luck, sorry I can`t give you the exact location of the G2/Focus block, manufacturers move them to different places every year.

Half the screen has ghost image (not focused)

Replace the convergence ICs. They are located on a large aluminum heat sink with STK numbers stamped on them. They cost about 10.00 each. They have to be soldered in. Let me know if you need anything further.
