How do I adjust the HD quality for a crisper picture? I have tried Magic Focus, but need to know where the sharpness or contrast can be tweeked .

Digital TV uses less airspace than analogue TV, so after the digital switchover there'll also be more room for services such as high-speed mobile broadband and high-definition television (HD TV).

There are actually two adjustment access holes (focus and contrast) on the back of that model. Here is a makeshift map...

On the back of the set mentally divide it to a left and right half. About the middle of the right half and around 4 or 5 inches up from the bench there will be two 1/8" holes. one on top of the other and about 2" apart. Slip a "pocket" sized flat head screwdriver into the lower hole and feel for the blade to enter the slot and gently turn either direction to adjust the contrast to your liking. The other hole above the "contrast" hole is for "focus" and really should be left alone.

The entire back cover can be removed by taking the four screws out of the corners and slipping it off. Then you can actually see the adjustment controls if you find getting that little screwdriver into the hole would be easier with it's clothes off...

I have a few ideas but they all will require some more information from you. I know these sets very well-if you fixed the convergence problem my hat is off to you--it can be a do it yourself job but not the most easy set to do it on.

Let me assume you adjusted the convergence in the customer mode--it does on any of the HD models have to be adjusted in the regular and then the HD modes.

The only other thing here that may be the problem is FOCUS. A simple way to determine this is to remove the back cover--turn the set on and call up the advanced convergence grid---then cover the lens for each tube one at a time--with red and blue lens covered are the lines in sharp focus or look blurry?

Repeat this with only red or blue not covered and see what you think--if one of the tubes is out of focus you will see it there--

There is also a TECH menu for adjusting the convergence-like the customer menu but it saves the adjustments into the set's memory--you will need to hit menu and a four digit code based on the actual model number of the set.

Check to see if focus is or is not your problem-easy to tell--green, red, blue lines will either be sharp or out of focus--if out ask and I will tell you the simple way to adjust that.

If this information has helped you rate this solution as I do this here for free.

First have the convergence IC's replaced these are the two large black IC's mounted on an metal heat sink.

Firstly, to get a "Shop" standard picture, you need to have a true HD feed. Usually a demo disc filmed in HD at 1080p, played on a true HD system at 1080p into your TV. Most broadcast feeds at present are on 720p.

However, you can improve the picture significantly just by changing a few settings on the TV:

Contrast: Change to about 65% of maximum. Too much
contrast gives a blurry / grainy image.
Sharpness: Change to about 20% of maximum

Also turn of any dynamic or digital contrast settings on the TV (if it has them)

thats how mine is. I don`t know who to ask how to fix it.

I think you'd have to look at how much a comparable set would cost. I know that flat screen sets are coming down in price.

One thing you could try is to adjust the focus control although if it just went all of a sudden, then this may not help. There are two controls on the flyback transformer. Follow the thick red wire from the top of the picture tube down to the transformer that it's connected to on the circuit board. There will be two controls, the upper one being focus (marked with an "f" or the word focus). Try adjusting this while watching the picture. A mirror may be helpful. At the same time, be very careful what you touch in there, any metal part could have high voltage on it. As long as you are just touching plastic parts you should be ok. A good rule of thumb is to keep one hand behind your back as you work so as you don't inadvertantly ground yourself to the chassis while touching something with a high voltage on it.

If this scares you a little perhaps it's worth taking the set to a shop for an estimate.

Hi

You can try and get more infornation for me.

Go into the the menu by pressing the WEGA GATE button on the remote. In the sub menu of picture adjustment switch the DRC-MF setting to off. It should read normal.

See if this stoppes your focus problem.

If it changes let me know for further directions.

There is quite a lot you can do. Go to menu, picture settings and select user 1. From here you can adjust everything from colour to contrast to warmth to sharpness. The best thing to do is to swith to XD manual adjustment and make sure the mpeg noise reduction is set to max. This removes artifacts and gives a better picture. Oddly, connecting via SCART rather than HDMI will give a more watchable picture if the HD broadcast is't at a very high bit-rate. I hope that helps :o)

*The brightness control setting determines how bright your picture will be. *The contrast control sets the gain of the video circuit. This determines the difference between dark and light scenes. Low contrast settings make the picture "hazy". High contrast settings make the picture more distinction between dark and light scenes. *The sharpness control determine the frequency response of the video circiut. High sharpness settings give better resolution but also shows more noise in your picture. Lower sharpness settings smoothe out the picture removing noise but also fine detail. It needs to be set for the best all around picture. *Picture Enhancement is pre-set adjustments which give you different picture qualities. You just select the one you like. Stargazer
