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

Focus I've noticed that the picture is out of focus on most of the right half of the screen. Is this easily adjustable?

    Does it mean anything that the focus problem is only on half of the screen?

    Also...what do you mean by "adjusting all the setting on your control"? Are there settings which would affect half of the screen?

    Anyone else have info on adjustments I can try myself?

Theire is 2 things could be wrong
1 cotaminated coolant in the crts this isnt something you can repair yourself and would need a proffesional to do this.
the other problem could be a convergence problem have ytried adjusting all the setting on your control if this dont solve problem then you probably need to get the convergence amps replaced this is also difficult to do your self as you would have to spend about 1000 pound uk on the right equipment to test not just the amps but any resistors that could be on way out or gone as this could lead to the convergance problem both these jobs are best left to a profesional sorry couldnt offer anymore help but their isnt much you can do yourself without spending a fortune on the righ equipment.
You would also need to be able to understand spec sheets and follow circuit diagrammes to trace any problems let me know what you want to do.
I can tell you where to get the spec sheet from ok and info on the parts you will need to replace but you will need to test resistors and ic to be sure on what you need to replace

    if it is only half the screen then it wont be any setting on controll sorry forgot what you said in message whilst typing sollution soz

  • paul proctor Nov 29, 2007

    The cheapest sollution is if you are not experianced in this sought of repair then the cheapest option to save you money is if you call someone out to look at telly they will charge call out fee and if they need to take it back to shop they will also charge for this the best thing to do is take it yourslf.

    This is a very common problem with this type of tv and wont cost to much to get repaired but just warning you that they will charge extra for call out and for transporting take it their yourself.

    It does need parts replacing it is not an eay fix you can do yourslef as other experts will tell you.

    But if you tell repair shop what the problem is they wont try and charge for anything else.

    If you goto this home page and on the left handside you will see a list of experts and then select more experts then keep reading down the list untill you see a tv expert then read his sollutions select view all somebody like tecman then look at their sollutions you will see alot of people with the sam problem as you hope this is some help to you ok

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.

Problem with viewfinder - focus?! I've been using my Nikon d3000 for over a year now. Few days ago I tried to take a photo but when looking through the viewfinder, the photo wasn't focused. It was...

There's a diopter control near the viewfinder to adjust the viewfinder to your eye. Try adjusting that while peering into the viewfinder and try to get the focus brackets and the data at the bottom of the viewfinder into focus.

I cant get the color right. its to red??? any help? i did notice with the back cover off, there are 6 adjustment screws

yes! those are the screen and focus adjustments. 3 for screen, 3 for focus. try this. go in menu....turn down color, brightness, contrast all they way down. you should then have no picture, but in your case a little red. then go to back of tv and turn those 3 screen adjustments all the way down. slowly turn the screens back up until you get barely a picture. because remember, your brightness and contrast is all the way down. the picture should be dim but seeable and with red, green, blue adjustments, make it a black and white picture. when balanced..... turn up color , brightness, contrast in menu. enjoy!

Pictures are out of focus on screen and when taken i cant seem to reajust the focus camera has been working fine untill i went to take a close up shot and now completely blurry .

If you are focusing On a subject make sure first that you are two feet away,

You can also try to turn On the blur reduction under setup menu. make sure also that your on auto mode or smart scene.

when taking picture indoor turn of the flash, you can do this by pressing the flash button On the camera

here are some basic troubleshooting

try to put your camera On a tripod or on the table to stabilize the camera then try to take a picture.

the technique of taking a picture Is first you need to half press first on the shutter button and you will noticed camera will adjust Now if the camera already adjusted pull press on the shutter button.

Blurry picture may caused if camera is not stabilized and may cause also if the flash will not fire correctly.

you may call tech support for further support toll free 1 800 235 6325

Red horizontal curvy lines

You need to turn the voltage on the red tube down slightly, also you would need to adjust focus to compensate for the lower voltage to the red tube. On the left and right bottom side of speaker cover are two round covers, take them out and there are 2 1/4" hex screws take them out carefully take cover off, there is another service cover same hex screws remove. You will see the focus block on the right side, tubes are labled on block. 2 knobs for each tube. Make voltage adjustments while tv is on a black screen, then for focus, turn color all the way off in the menu, and adjust focus until it looks right in black and white. These adjustments should only be very small; if alot of adjustment is needed, you may have other issues.

Veiw finder(eye piece ) out of focus pictures are fine

Use the diopter adjustment to refocus the viewfinder to your eye.

Point the camera at a sign or something with writing on and half press the shutter button to focus then move the little adjuster at the top right of the viewfinder until the image in the veiwfinder is in focus

Green picture

I'm not sure about this model but most projection tv's have a focus/screen control block usually located behind the front grille where the speakers are. The grille usually comes off easily. If there are no circuit problems you can adjust the red green and blue picture tubes there. Also the focus. It will be written somewhere screen and focus: Three for screen and three for focus. If you find the screens then adjust them slowly clockwise for increase brightness on the red and blue and you may have to reduce the green. Adjust for best picture. If the picture does not adjust too good then the tubes are weak. Only if there are no circuit problems Hope this helps

Dark picture (HELP)

Open up the back of the set but be very carefull. Notice a large black block with a large red wire that runs up to the picture tube. on one side of that large block where the thick red wire is comming out of are two controls, one should be marked focus or F and one should be marked screen or S. With the set operating normally and not touching anything else, slowly turn the control marked screen or S clockwish till the picture gets bright enough. If you go too bright the set will shut down or you see small thin white lines so back down on the control. then touch up the focus and your good to go. good Luck.
