Hi and welcome to FixYa,

The East-West correction circuitry together with the Pincuhion and Parabola correction are essential part of the horizontal deflection in a CRT base TV unit. Normally, ICs are used and therefore would be the prime suspect if failure in any of these correction circuitries. Examples of ICs used are AN10294, TDA4950, TDA 8145 and still others.

This of course requires opening the unit, perform voltage measurements, determine the faulty component and subsequent parts replacement. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Good luck and Thank you for using FixYa. Happy Holidays.

EAST/WEST CORRECTION


Enter the menu and choose initial setup.

For Vertical correction choose VERTICAL POSITION and make adjustments.

For East West, the menu will only be available if the incoming signal is 480p.
If it is you will see a choice for DIGITAL IN and select a size.

I have a Samsung projection tv since 2004. My problem is: when the tv is on for approx 45 to 60 mins, the picture starts to flickers at the edges,contracting and correcting itsself in size. I suspect that...


Yes definitely, the power supply electros will do this. Also the b + filter cap which is usually a 220mf
160volt will do this also.

The east west circuit can also produce the same problem. in this case a dry joint sounds like the culprit.

PICTURE


By the picture that you have supplied with the question you have a rear projection tv. The problem you are describing sounds like you have had the convergence module in your tv fail. Depending on the age and make of the tv, the repair costs ( if out of warranty ) can be prohibitive. The convergence module on rear projection tv's not only is in charge of bringing the 3 different color images together into a watchable picture but also handles the east west correction ( concave / convex aspect to the picture or lack there of ).

Hello.We were given a grundig tv. ws70/3020. We cannot find the information,regarding the pin cusion. The picture seems to bevell all the time.Would you be kind enough to let us know how to fix this...


Hi there!
My guess on this is that you have an East West fault on the set and therefor you have the Pin Cusion or bowing on the sides. The settings are usually only available in the service mode. I do not have the info on hand but I will check wether I have for this model. Regards, Jus004

Rca projection tv has no picture or osd


Check the bulbs. If one is burned out, you will get this problem. The bulb is easy to change but will run you about $300.
