Check state of capacitors related to the ABL circuitry starting from those located close to the flyback transformer. Also check for resistor out of range in the same area.

Sanyo tv color doesn't look good...it shows ghost images and is too dark. I went into tv settings to adjust the colors and brightness but that only helped a little.


Sounds like a weak output voltage transformer...the set is shot...live with it or get a new one...if it is still on warantee, call Sanyo!

Dark picture, green screen


This could be several things. At its best you have an open resistor near the flyback. You may have a bad ground on a color output transistor, or a bad ground on a color output resistor. These are located on the small board connected to the CRT. In really bad cases you may have replace the transistors, or resistors. But in worst cases, and I do believe its true, you have a bad picture tube. I would not recommend a repair. I have seen this problem with many, many TVs of any brand. You are smarter to purchase a new TV. Thanks for asking and show all hands of support!

Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV


You can try adjusting the Red color output. (Very touchy adjustment)

If you take off the front cover/speaker cover, there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.

Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

DARK AND COLOR RED


It is more than likely a convergence issue rather than a color issue.

Mitsubishi WD-52631 shadows and blurs in dark lit movies


If you are getting the same problem with both TV monitors it could then be assumed it's an input problem to the TV monitor. If you are using a digital output from your receiver it could be the cabling. If you are using an analog output from your receiver it is probably coming from the receiver.
Digital video processing does have issues with darker scenes.
Can you try another video source seperate from the receiver like a DVD or better yet an analog VHS, if you still have one. Good luck and let me know.

This has something to do the brightness chosen. In the manual mode, if you choose a dark output, the output will have tis area also; if you choose, lighter output, it will omit. In the auto scan mode, the scanner decides what is the best output.

No Picture


Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
