Loewe TV with pin cushion distortion

After approx 20 minutes once TV is switched on, the screen distorts with a pin cushion effect - the sides of the picture curve inwards. If the set is left on, the apex of the curves become staggered and the picture that remains, reflects this distortion across the screen. Can you please advise the probable causes and possible cures. I'm an end user with an electronics background presently unable to locate a repair manual.

    Cheers Troy, will give feedback as soon as I can.



    Many Thanks

    Troy, the set developed another fault - psu due excessive use with pin cushion problem. In the end for swiftness had to call a service engineer. If I'd acted more quickly your solution would have rectified the problem. Caps kept as souveniers.

    Kind Regards

Yes if you could give me a model #, it is probably a diode shorted in pincushion area, or a capacitor.

    Yea this is a unique model, you have a leaky capacitor in your pincushion circuit. If I had a picture of it maybe I could point it out.

  • Lashawn Robinson Oct 09, 2007

    From what I see in the picture, it looks like you have the same blue caps that the RCA has in it that goes bad. If you look under the red anode lead from your flyback. This is the part that goes to the picture tube. there is a blue looking box type capacitor. These are the caps that goes bad in RCA models. Also you have the gray type right next to it. Look closely at these caps sometimes you can tell which is bad. If the sides are not smoothe, but rounded out and looks like it's about to explode then it maybe bad. Also look for something that may say pin cushion area, I cant tell from the picture. But check and if you find something change it.

I have Prima TK 2951 CRT TV AND i have vertical problem. Which capacitor i should change to fix picture from sides have corregations from down to up


You're talking about the pin cushion distortion; I presume. If this is the case, there is a separate circuit to adjust pin cushion distortion. Contact any service technician to rectify this problem. This is a skilled work. If you wish to get some details; check the site linked here. Pull up older posts.

Picture is too large to show on screen


Check its "Pin-cushion" section circuit for the fault. An IC is used there to control the pin cushion distortion. If this IC has got faulty, this type of fault can occur. This is actually a skilled work. If you are not ahndy, seek any technicians' support.

SONY KV SW 212 M80 Screen sowing pin cushion distortion. Screen is squeezed on the side and the side is curved inward.


Hello
Its pin cushion distortion circut had some trouble with it. There is an Ic and one transistor wich controls the pincushion effect. In most cased the trasistor that fitted on a heat sink, will have loose soldering at its terminals. this transistor will heat up during working, and repeated heating an cooling will make solder terminal loose contacted and it is normal fault. locate this transistor, very near to the LOT, resolder its solder terminals by applying a little more solder. It is best to resolder most of the surrounding solder terminals of high watt resistors, without making any solder bridge in between the solder points. If these does not helps you, replace both the IC [an eight solder terminal one, small IC] and the pin out transsistor described earlier at the same time. this will solve your TVs problem. OK.

You have bad capacitors and possibly a vertical IC that is going bad. And check for bad grounds in and around the IC and caps!

Green wave-like color distortion over reds


do you happen to have any speakers of any size within about 3 feet in any direction of the tv?? move them if so, I have large speakers about 5 feet from my tv at home and i still get some distortion once in a while with red and dark green streaks.
