Re: Picture problems

Retrace lines on picture, 60V on RGB transistors
C700 (100nF, 250V) seems to be leaky, but main problem is R723 which had gone from 27R to 1.2M, both on CRT board

Toshiba Rear Projection TV picture color is now a greenish hue

Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website: 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from  

Hope this helps :)

Sony-kp51ws510 picture turns to a blue hue with flickering colors

hello there this is an easy fix unplug the tv and take the back of the set, once inside the set you will see 3 coloured bulbs and a big mirror in the back theses over time get dusty and dirty and if you smoke it can get really bad you simply just need to clean the bulbs and the mirror with computer screen wipes or some sort of window cleaner be sure not to get everything wet inside this should sort if for you nice and clear again!

Thanks For Using FixYa

My screen has gotten much darker

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.

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.

1)Please verify your model # from back of set......

2)Reduce the color to minimum or tune in a black & white chan.

3)Remove lower front grill cover & access panel.....locate the
focus / screen control block...turn blue screen control slightly,green and blue must mix to equal gray

4) reset color to normal level.......reassemble

Problem with color

Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck
