Samsung HLR5067 has no green color in picture


I know this may seem dumb but if you are using component video (the red green blue with the white and red audio cables) it could very well be that the green cable (carries the green signal) is the problem. try changing the configuration (ex: use blue to carry the green signal and vice versa) if the green starts to work and the blue stops then its just your cable.

I have a Toshiba CT-90121 and my convergence is off. I can adjust the blue and red in the menu but cannot aline them with the green crosshairs. Do I need a new green projector or something else?


You need to remove the convergence Board and repalace the convergence IC's and and replace electrolytic caps and check for resistors that have changed in value. You can getb the parts at www.mcmelectronics.com com or just purchase a new board at www.partstore.com .

I was given this model tv. The green and red lights on the front are flashing. Says to replace bulb and close lamp cover correctly. I am missing the lamp cover. Is that going to be a problem?


U mean the Lamp door cover?Yes?Tv might work,might not.Don't know never tries to turn the tv on before without a Lamp door cover close before.There is a blue safety switch though must be press down when the Lamp door cover is close.Test it out.Why don't u just take a piece of tape and tape that blue safety switch down tightly,than turn on the tv.If the tv message that said close lamp cover correctly disappear.Than yes the tv will work,without the lamp cover closed.Now u just needed to do a replacement of the tv projection lamp only that all.

Have a 46f500 hitachi projection television. Started out with a blue reversed arc hanging down on upper right. Now images are not focused, and red, blue and green are layered. Double images. I looked...


It is a convergence problem and set uses two of the STK-392-150 CHIPS. Both will have to be replaced and the set adjusted.

for more information let me know if you can solder and your skill levels.

Alignment will not work corectly, still have blue and yellow show


Make sure the Size and Linearity adjustments are not cranked too high. This can affect the ability to move side to side. Center green first and then red and blue. Some pattern generators can produce a horiz shift. Also, check for a horiz start position adjustment. If blue is way off from Red and Gren then you have a bad amp.

Red and green do not light up


Start by raising the screen control for the red and green to see if they have any type of luminance.

Toshiba 55H70 Green CRT


Whgat you should have done was to take off the red tube socket and put that socket on the rear of the red tube onto the green tube. If the green worked then you know the green tube was good and the driver was bad. If a set is over 6 to 10 years old, and if you replace one tube, It will never get a good grey scale(B&W). I hope you didnt replace the tube when a driver was bad!
