Manual for a NEC TV model FS-6315S


Again not a question about Motorcycle Protective Gear. The link to the customer support division at NEC is posted below. They should be able to provide you with the link to download the manual for your particular model.

I have a thin line in my tv and i dont know what ic no.to replace?


The fault is a failure of the deflection circuit and since you have not specified whether it is a vertical or an horizontal line the section failed will be related to the position of the line.
If horzontal the vertical IC or the section related is faulty and if Vertical the horizontal section., Now this can be the deflection IC, teh deflection coils or even discrete components like capacitors or resisitors in this section which will require a signal trace with a voltage test before the absence of the sync pulses are confirmed and the section identified.
I request not to change the IC unless it is proved but you can solder the vertical IC or the section concerned -- if there is dry soldering.

Sony kv-32fs13 4 blink code


The tech is wright about the deflection board having a fault. This failure is found in the vertical deflection circuitry.
The quote is the one that seems to be a bit high, instead of getting this TV fix; I would save that money to buy another TV.
Good Luck.

Screen Smaller on Orion1934" TV


Hello Falken94,

Your TV is losing what is called vertical deflection. This might be caused by the vertical coupling capacitor going bad, or by the vertical deflection coil on the yoke transformer going bad. In any case there is not enough vertical deflection signal getting for the vertical output section of your TV to the vertical coils on the yoke transformer. I would suggest that you get this looked at by a qualified TV technician, due to the nature of this problem.

I hope this helps,
Thank you,
Shuttle83

My tv has this lines that bend over the front top of the screen and when an object moves through the lines the image appers from the the top of where the line begins...and the tv goes black every once and...


This sounds like a vertical deflection fault. There are some components that are failing in the vertical deflection area that are starting to fail. It is very common in many of the sets that there are electrolytic capacitors in the vertical amp section that are gong out of specifications.

When you have at the top or the bottom of the screen where the vertical axis is compressed, and the picture in the compressed area looks like it is inverted and going over on itself, this is called "vertical fold-over".

An experienced TV service technician should be able to service this for you.

or read below:

This sounds more like a vertical deflection fault rather than a horizontal fault. I have my doubts has anything to do with the flyback, unless it is one of the supply voltages from that section.
Most of the common failures in your model series for this type of fault are many of the electrolytic caps and cold solder connections to the output devices since they run very hot.
Use a heat gun and circuit freeze to troubleshoot for the fault. Heat the caps in the vertical deflection area, and then test them with an ESR meter. You can then use the circuit freeze to test the questionable caps in the cold state after you find them to be failing from heat.

There is a vertical centering fault. I have had some capacitors in the vertical deflection amp cause this type of fault.

You will have to bring the set in to a service shop to have it serviced.

Vertical rolling in t.v.


Kamal, You need to find the sawtooth waveform which is generated by the vertical oscilator. There will be a pin on the IC that should show the waveform. If it is not there, then the IC is bad. If it is there, then there is probably an amplifier stage prior to the deflection yoke that has a problem. Either way, the sawtooth wave is not getting to the deflection coil which is why it is rolling. Ther might also be a coupling capacitor which has opened up. Hope this helps.
