Why does hotpoint maschine, only 15 days old, suddenly shrink wool clothes?


I was under the impression that only HOT water will shrink wool clothes. Did you buy mistake set or forget to set your temperature setting. Think back to the previous load that was washed. This may be the reason for your shrinkage problem. GOOD LUCK FRIEND.

Tv picture shrinks


This is a common problem on certain models of Philips Magnavox TV sets. The most common symptom is the screen will shrink and expand over and over. After the TV heats up for a while the video will work like normal. After a few weeks or months your TV will eventually stop working and not have video. You can get complete parts and instructions from www.TvRepairKits.com

TV works fine for a while, then the picture disappears.


I would just replace the TV, the parts are not going to be made to repair this. The set is just to old.

Screen shrinkage


The vertical shrinkage is a fault in the vertical deflection circuit, suggest replacing capacitors around that area along with a vertical output IC. I can provide more info if you've got some electronics experience and going to try and tackle it.

Toshiba 36 inch TV (8 Years Old)


Hi,

If the shrinkage is just the top & bottom then it is relatively easy/low cost fix. Most probably, a capacitor in the vertical section is nearing end of its life. This would be the biggest of the bunch and would be something like 47uF/50V.

If however, the shrinkage is on all four sides, then it is the master power supply that is at fault. Chances are the main B+ is getting low which cold be caused by the big filter capacitor or an erratic regulator. This is not a simple fix and would require the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Shrinking picture


All symptoms indicate a problem in the vertical circuit,the first thing to look for will be loose conection on the vertical output IC,sometimes this IC goes bad completly and it needs to be replaced.If you are familiar with soldering electronics you can take care of it but if you are not too familiar you can play it safe and take it to a servicer ,it will be a lot less expensive than if they come to your house.Let Us know how it goes or if you need more information.
