Question about Toshiba 35A44 35" TV

1 Answer

Toshiba 35 I have an older (90's) vintage Toshiba 35" TV that has a green color on off problem. I took a look at the circuit board on the back of the CRT and there is a cold solder joint. Can I just solder this, or is there a risk of high voltage here. I don't want to mess with it if there is high voltage issue.

    Thank you!


    I will take a good look at the other joints. I do a lot of soldering of electronics and tiny computer parts, so this is no problem, just afraid of the voltage issue.

Turn the tv off ,disconnect from power source , then you can
wait 1 hour appx. ,for the crt to discharge it self ,or you can
being very  carefull discharge the crt by inserting a long
screw driver under the ground strap that runs across the crt
(thats the metallic one ) the other screw driver under the anode
high voltage cap (thats the one that connects to the top center
of the crt) then short the two screw drivers together ,you should
see a little spark if there was any voltage there ,after that you
can solder  all the cold solder joints.
May I suggest that you check the main chassis also for cold solder joints.
I have checked many a TV.,and I always check the main chassis  to prevent callbacks.
BE SURE  NOT TO CREATE SHORTS WHEN YOU SOLDER
USE A 40 WATT SOLDERING PENSIL/IRON
TAKE YOUR TIME. YOU SHOULD HAVE NO PROBLEM.

Our tv keeps changing colours to blue red and green


Your television have color problem.That symptom is cause of loose connection or cold solder in chroma section and color output driver transistor of CRT board of your television.You can fix that problem by resoldering the chroma section and crt socket section of your TV.first thing to do is open or remove the back cover of your TV,then you can see the crt board connected to picture tube.Resolder that parts,specially the color output transistor the red,green and blue driver.Resolder also the chroma section.You can see the jungle ic,thats the color ic.Make sure that there's no short circuit when soldering the PCB board.After the resoldering turn on the TV and check if color is normal.Thanks..

I recently purchased this type of TV from someone who sold it online. Its a 32'' and has a memory stick feature. I can get the TV to come on and the picture looks great but there is no color to the images....


U Know basic soldering,have soldering tools and solders?Take ur tv back cover off,resolders the video board the connect to the CRT(tv tube).Also,resolders the CRT yoke connection to the main board,the connection have GREEN,YELLOW,BLUE,RED to one connection's plug to the main board.You do the above ur chances to get colors back are 80-90%.U can tries to reset the tv back to factory setting,by unplug,replug it an hour later,this method 50/50 to get the colors back.

Problem on CRT board, this is the board on the back of the tube. It has a open transistor for the green.

Red & Green seem "off centered"


Your set uses the 195 series chassis, which has separate components for each of the 6 convergence channels and a separate power supply for the convergence circuits. If all 3 colors have drastically shifted, especially around the edges, then chances are your convergence power supply has stopped working. This is usually caused by the failure of the STK730-010 switching IC. If one of the colors has dramatically shifted by itself then something has stopped working on the convergence board. Sometimes I see CRT coolant leaking onto the convergence board as the cause. In either case this is something that should be repaired and realigned by someone experienced with RCA projection TV convergence circuits.

It could be a bad solder connection on either the crt drive board that attaches to the neck of the picture tube, the video processing circuits on the main printed circuit board or the picture tube itself. If you can lightly bang the sides or top of the set to get the symptom to come/go, then it is most likely a bad connectiion. If, when the screen goes green, you see fine white lines diagnonally across the screen about a half inch apart, then it is likely the picture tube.

Green is not being displayed on my TV


If you have experience troubleshooting solid state TV sets, you should be able to tell by a couple of voltage measurements if its a problem with the picture tube or the drive circuit. Simply take the multimeter and compare the base voltage of the green drive to the red or blue drive transistor. If the voltage is about the same, measure the collector of all three. if the green voltage on the collector is higher then the others, then theres an open between the drive transistor and the crt element. this could be an open resistor, a bad solder connection on the crt socket, or an open picture tube element. If theres no voltage there then your going to have to trouble shoot the drive circuit.
