Please help me, i'm repairing 14" old model television.. it don't have brand name but it is using 47C434N-R201 system, TA8680N video chroma IC, 30115 regulator, my problem is it don't have...

Good day!

Try to check the base of the horizontal output if have a signal from the chroma or jungle i.c it should have 5-7vac to trigger the high voltage.If no voltage try to hang it and check again if the voltage appear while you hang it,your ply-back got partially defects replace it with the same type and ratings.
Next,if you already hang the base of h-out and still no voltage on it and the chroma i.c is new.Trace the line from the base of h-out to the chroma/jungle i.c.Test the parts that pass through that line such as open/change value resistors.

I hope this solution will be helpful.Thank you I'm very glad to share my idea.Good luck.

Our Samsung slim fit t.v. is displaying a completely RED picture. Any trouble shooting tips?

if the problem is always red picture every time you open your TV unit i may say that there is problem in your CRT chassis board or at chroma driver. open your unit then pull out the chassis board clean with lacquer thinner and then check possible loose contact re soldered parts at color amplifier section and parts at chroma board which is the driver of red, green, and blue gun. it is connected at the neck of picture tube. after you try all this option test your unit then observed if it is ok now. if still doesn't change red picture again check defective parts at chroma board pull out the driver transistor of green drive since the problem is reddish so there is no green drive check if it is leak or shorted also check open resistor. also you need to consider is the voltage of all the driver transistor are almost the same to have good picture.

I have no color on my Samsung Flatscreen TV

Hello,

This means absolutely no color - equivalent to a black and white picture. Not even a hint of color.

First, confirm that the source is actually in color - try another channel or input device.

Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable transmission.

At this point with a confirmed color signal source, there is a problem with the chroma circuitry.

Note that to the average person, the obvious question becomes: is my color picture tube bad? The answer is a definitive NO. It is virtually impossible for a defective CRT to cause a total loss of color. A defective CRT can cause a lack of a primary color - R, G, or, B or a short between two colors which will mess up the color but is not likely to result in a black and white picture.

Some possibilities in no particular order:

Weak signal or defect in tuner/IF causing loss of signal strength.

Coler killer set too high (internal control) if it has one.

Defective part around the chroma chip/circuit. Faulty color oscillator.

Bad connections in area of chroma chip/circuit.

Defective chroma chip (don't suspect this first just because it is probably very expensive).

Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.

I had one set where a $.02 resistor decided to open up causing just this problem - perfect BW picture, no color. Another had a coil with a broken wire.
