use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

toni, you`ll need a tv tech for this problem, spark gaps need to be cleaned, crt sockets need to be cleaned and crt pins on all 3 crt`s need to be sanded, this is a common issue with this model set, good luck, BMW Rider

Could be the blue CRT shorting out. I had the same problem but with red. Eventually it shorted out completely. If it is only 2.5 month old it should still be under warranty and they will fix it.

These TV's are known for polluted coolant in the picture tubes.The coolant is between the lense and the tube. The factory has a Service Bulletin about this problem and they say to change the coolant in each picture tube. This will make the TV look like it did when it was new.

My sharp 32c540 picture is dark since i bought it brand new 6 years ago.


You may just have to make a different kind of adjustment.

This is what is called a direct view or crt type TV.

Inside on the main board (see attached photo) is the "flyback" transformer.

Note the two little controls embedded in it----top one is focus--leave it alone.

Lower one is SCREEN and a very slight upwards or right adjustment will bring the overall brightness up.

You want to adjust it just till with brightness on set all the way up you have a normal picture.

Too much and you get excessive brightness and trace lines and or further too much shuts set off.

Some sets have two holes in back of cabinet and small tool can get in and adjust the LOWER or screen control and others the back has to be removed.

Lay set face down on padded surface, remove back screws and set upright---do not touch anything inside with set on when you make the adjustment--control is plastic and a plastic tool a good idea--I have used regular screwdriver but know what not to do.

Let me know if you have questions 98% chance just need the Master Screen bumped up a little bit.

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 very dark, Brightness all the way up. Contrast does not adjust


I have the same problem. I was able to temorarily fix the issue by taking the back cover off and blowing all of the dust out. But this only worked for two days. Now the problem is back. Did you fix the issue with your tv? Thanks.

My picture on my Hitachi 51F710A has a very strong red/pink tone over the entire screen but is slightly worse on the left had side. I've tried all the adjustments on the menu including the magic focus but...


Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Dark picture


you know it sounds like the same problem i had....
look this is something you can try.... "turn the tv off and unplugg it!!!"...you'll need to take out the lower front part of the tv......(where the speakers are to be exact) on each lower end you will find 2 screws..Be careful it will open to the side and there are many wires, i suggest you mark them to know where to put them back...then right in the middle there will be a black cover with about 5 screws..take them out....and look at the very bottom you'll see a thing with 6 pegs....the top ones are for the screen "DO NOT TOUCH THEM"...the ones on the bottom are for the colors...re adjust them...the left one it's for blue, the middle one it's for green and the last one it's for red...

I had the same problem after i moved....and after i re adjust that the tv looks super...
i hope that helps..:P

Screen is Extremely Dark!


Good Day, Cary;
PICTURE IS DARK WHEN OSD CONTRAST MENU ADJUST LEVEL CHANGES.
Cause: SHORTED ZD-309.

Also, increase Screen controls at front of TV and see what pix brightness does . Hopefully you did check brighteness & contast levels. When adjusting Sreen controls set contrast control at about 90% and brightness at about 50%.
Good Luck, big IRISH.

Vs 4561 weak picture


Good Day, Techwanab;

Look for this to be your problem: CHECK FOR OPEN L2C50 PART #325C146030 ON THE SIGNAL PCB, OR BAD CONNECTIONS AND LEAKY CAPS IN THAT AREA.

Hope this was helpful and not too late.

Good Luck, big IRISH.
