It is known as pin cushion effect. there are settings for this. You can set it right from the Menu.

    There are no components involved. It is the settings that have to be adjusted. It happens in computer monitors too. And sorted out with the on screen display settings menu. So would it be in your case too.

Hi,

This issue is the scan correction or East-West control
You see as the set tube gets bigger so their is a greater need to control the scan
This is achieved by incorporating an East-West correction circuit and its here where the fault lies
You have dry/cold joints in this area which may have got that poor a contact that it no longer makes
Also the poor joints could have damaged the transistors or loading coils in that area too
Its a none do-it-yourself, i am afraid due to the job being done right first time otherwise if something is overlooked it would lead to the new devices failing again!
A technician would probably charge $90-$100 for this repair


Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The picture on my Sony is shaped like an hour glass


There is an apparatus on the back of your picture tube called a yoke.This distributes your picture on your pic tube uniformly.If this or the circuits enabling it malfunction,then you will get distortion-namely an hour glass shape.Tv has to be trouble shooted.

Tv screen has slight hourglass shape


A common fault are some of the electrolytic capacitors failing in the pin cushoning amp section, and probably in part of the scan amplifiers.

To service this will require the proper training and set-up to troubleshoot the set.

Take the set to a service center for an estimate. The cost can be at least an hour or two for the labour, and then the cost of the parts on top.

Big cap in the regulation ckt is bad. Depending on model could be various values, a shop could use their ESR meter to find and replace it.

Picture shaped like hour glass


You have a PIN CUSHION problem, is usually a bad capacitor or open resistor in the above cicuit. Check all the caps around the horizontal output transister for ESR leakage.

Tv picture shaped like hour glass


The link you posted has been deleted, so I cannot see the picture you posted. If the sides bow in like an hourglass and the red, green and blue colors are still aligned then there is a horizontal width or pincussion problem, but if the sides bow in and the 3 colors have separated and are no longer anywhere near aligned then you have a convergence problem, both of which should be serviced by someone with experience in servicing projection TV's.
