Question about Televison & Video

3 Answers

Following a loud bang sound I lost picture quality to the point that the blacks seem to cloud the screen. If I adjust the brightness levels up it helps but then the screen washes out and it is also very difficult to even see images with any type of ambiant light in the room. Is this worth repairing this 2 year old 52" LG Plasma?

The loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..

Sure it is worth, call LG and buy a warranty extension, this will cover the whole repair cost.

You find LG number listed on the owner manual.

    Contact LG , using the number from user manual or the one listed on the LG website.

    Here is also a private provider selling warranty extension, but I do not know if it covers your area : ProTech 3 Three Year Extended warranty for LG

    Ask detailed information on conditions if you buy from private.

    One year extension from GE will cost $150 or so, and will cover all repairs for one year.

Toshiba 37XV505D. Sound but no picture


Hi,
Since sound is ok but there is no picture, you should try the following:
1) check whether brightness & contrast controls are adjusted properly. If necessary increase level of these controls.
2) If brightness & contrast are ok and even then there is no picture then most probably, there is fault in the horizontal supply circuitry which drives picture tube and is responsible for picture to appear on the screen. you will have to take the TV to service center.
Good luck and Good day.
Rating the solution is appreciated please.

Why video quality in mac is not good it seems


Try going to your System Preferences which is in your Utilities folder located in your applications folder. In system preferences, click on the button called "Displays"... from there, adjust your brightness (turn it up).
Also, if video quality is bad in Quicktime - open quicktime and go to Window tab located at the top right near the help tab. Then click on Show AV Controls. You can adjust brightness from there.
Also, within the Displays button, try calibrating your monitor by following the simple instructions.

I have a sony kdf-46e2000, there is a pinkish stripe on the top and bottom of the screen, what is causing that?


Looks to me as an serious (but not uncommon) PSP board problem with Sony plasmas. Contact a Sony service center.

What problems have people had with quality control on these displays? Are they covered under warranty?
  1. Certain displays emitted an extremely loud buzz. This was covered by warranty repair.
  2. Certain displays had a problem with the Y/C delay on their S-video input. This was also correctable.
  3. One person reported red vertical lines on his display. Was this covered by warranty? Was it an input problem or a pixel problem?
  4. Afew bad pixels here and there are not covered under warranty. Largeclusters are generally covered. It's up to Sonys discretion. On the plus side, however, bad pixels are becoming increasingly rare. Mostpeople are reporting no bad pixels at all!
CALIBRATINGWhat needs to be calibrated on a plasma?
You needto calibrate most of the same things that need to be calibrated onother displays. About the only things that don't need to be done areconvergence and geometry. You can usually tinker with picture size andposition, but there's no need to deal with keystone or pincushionadjustments, etc.What is white level? What is black level? How are they adjusted?
Theadjustment for white level is usually labeled "Picture" (as onPanasonics) or "Contrast". "Brightness", on the other hand, refers tothe black level. Yes, this is apallingly counter intuitive. This FAQuses the terms "white level" and "black level", since they betterdescribe what you're actually adjusting, and they're the terms used byAvia and Video Essentials.
How do I adjust hue and saturation?
In another mysterious choice of terms, hue is controlled by the "Tint" setting,and saturation is controlled by the "Color" setting. This FAQ uses theterms "hue" and "saturation", since they're the terms used by Avia andVideo Essentials.
How do I set the white level on a plasma?
Youset the white level by adjusting the "Picture" setting. You will needto use a different test pattern than you would for a CRT. For both plasma displays and LCD displays, you should use the 10 IRE grayscalestep pattern. There are two criteria you want to match on your plasma.
First,you need to make sure the white level is low enough that your displayisn't thresholding (or clamping) bright levels. You should set thewhite level low enough that you can see each of the 10 IRE stepsdistinctly. The Sony seem not to exhibit clamping (in my limitedexperience), even at factory defaults, so this criterion may not beterribly useful.
Second, for the health of your display (e.g.to avoid burn-in), you should turn down the white level. Just becauseyour display can display blindingly bright pictures doesn't mean that it should. Plasma displays should be set between 21 fl and 25 fl light output; the Sony comeout of the factory at about 30 fl. On one ISF-calibrated Sony, 23fl was roughly equivalent to a Picture setting of -20 (in the usermenu, not the service menu). To set this precisely you'll need to bringin a calibration specialist, but you can do a lot of good by justdialing down the white level a lot. After seeing the display at 30 fl,23 fl will see very dim. But after a while, you'll find that 23 fl isplenty bright.
How do I set the black level on a plasma?
Youset the black level by adjusting the "Brightness" setting. You can usethe same test pattern you would use for any other display.
How do I calibrate grayscale (calibrate the color temperature)?
Unfortunately,this is one you can't do yourself. You need special equipment tomeasure the color. In fact, most ISF technicians lack the equipmentspecific to plasma calibration (a $15K gadget known as aspectroradiometer). But even the standard color measurement equipment(which calibrationists do have) will do a great job.
Thatsaid, one person who had his Sony display calibrated by an ISF specialist said that the Cinema / Warm setting was reasonably close to6500K out of the box. Using that setting is probably the best you'll doon your own.
If you're really determined to screw up yourdisplay, the RGB drive and cutoff settings in the service menu are used to adjust the color temperature.
How do I adjust the color decoder?
There are several issues here. Generally speaking, the Panasonic decoder seems topush blue a bit. The R-Y Axis Angle and B-Y Axis Gain in the servicemenu are used to correct this behavior.
There used to be aproblem on some Panasonics with the Y/C delay on the S-video input. Seethe Quality Control section for more information.
How do I adjust the gamma?
On the industrial model, there is a set of Advanced picture settings. Go to the Picture menu, turn Advanced on, and then hit the down-arrow. In the subsequentmenu you can adjust quite a few parameters, including select from a fewgamma settings.
This advanced menu appears to be missing from the consumer model.
How do I calibrate my consumer model given these missing menus?
Thereis apparently a way to activate these menus. Perhaps you can find acalibrationist or Panasonic technician would can turn them on longenough to do the calibration.
What's the overall calibration procedure?
In general, the order Avia sets out is the correct one. A more complete list is:
  1. White level (picture)
  2. Black level (brightness)
  3. Repeat (1) and (2) until you have a good balance.
  4. Grayscale (requires special hardware and mucking about in the service menu)
  5. Sharpness
  6. Hue and Saturation (tint and color)
  7. Color decoder (requires use of the service menu)
  8. Repeat (6) and (7) for red and green until you have a good balance.
SERVICE MENUHow do I access the service menu?
In a word, don't. See the service menu warningabove. If you're bound and determined to make use of the service menu,buy the service manual. It contains more than enough information foryou to ruin your display and/or kill yourself.

Photosmart C6300 pictures are printing very wet and grainy. printer is also very loud - almost as though the parts were scraping and banging.


Sounds like you have the wrong paper setting in your print properties. I would use photo or high bright 24lb paper and set the paper type in your printer properties prior to executing the print job.

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

Aadjusting screen colors


They should be adjusted to set voltages. however it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels. Hope this helps.
