Orion TV stv2767a

Regards: How can I control the vertical height, since the image is a bit stretched. the tv has two trimesters; one is vr402 vertival line and the other is vr401 vertival position. I moved them, but you can't control the vertical height. The vertical line barely picks up the vertical a bit and the problem cannot be corrected. The other control, only gives position of a step, puts the image a little down or a little up. What can I do since I don't have a plane?

which chassis uses that orion, it is usually the devalued capacitors of the vertical stage that cause that failure

Identify the chassis used by the device, because by brand and model I did not find any information ... If with the preset it does not modify the "values" the fault mostly goes through capacitors in poor condition. Doesn't it say Vertical High?

The Chassis is TMC567A and has no quarter that says vertical high. I have already reviewed most of the condores unless it is one of those high capacity that I have not yet reviewed.

Half silly question? Won't the TV have a zoom option? I found a diagram of the chassis, apparently of the Zenith brand, I did not find a service manual to think that it is necessary to enter the service mode to regulate the vertical height parameters.

In the publication of the model I was wrong. The model is STV2763A CHASSIS TMC567A
The vertical outlet is placed in the same heat sink of the horizontal outlet. I notice that it is very hot, will it be normal?

Did you change the capacitor or capacitor C417 / 1µF to 50 volts?

Responder

If I change it but that C417 capacitor appears to me as 47uF for 50V

Is that the reason for the vertical output overheating?

In the diagram I downloaded by the chassis, it says that the value is 1 µF per 50 Volts, it is in connection with the VR402 preset ... I don't know why it will heat up the components mentioned ... I don't know if he was wrong when replacing the condenser or coming from another side ...

I already put the 1uF x 50V and the tv has the same symptoms.

And well it is an abance ... To adjust the vertical height you have to enter the service mode, you have to get the TV remote control, ask the owner ... I do not know what it is, in the service manual there are no photos of the same...

Thanks friend neg2013. With that diagram I am sure to resorb the problem of Orion TV. When fully resolved. I will comment.

Compare and comment if the components of this capture is what you find in the chassis, apparently I could locate the service manual, but I cannot decipher the English in which the subject is developed, my English is very basic, and I tried to deduce what it says but I could not ...

This TV initially burned me a vertical outlet that I bought. I don't have time to cut the power. The reason why the vertical output is exploited, was being given by two zener diodes in series that measured as good, when measured outside half on both sides indicating leakage. I changed them and I no longer burned the vertical sa. Then another fault that I corrected. The vertical height stretched. from both changing condensers for new ones I got the C418 which is 1000uF 25V. When I see the plan that the friend gave me, the condesador neg2013 appears with a triangle indicating that it is a critical component. Which is understood as a value that should not be altered and the one shown in the plane is 2200uF. then I put a condesador like the one that says the plane and double problem corrected. Overheating improved and the vertical height was corrected. Many thanks to the Community of technicians.
