Sounds like problem in B+ voltage line to horizontal output transistor. Possible bad filter capacitor or leaky diode in power supply.

My 27inch Sanyo tv screen is shrinking-sides have curved black is=nstead of the full picture. Can you advise what this might be?

That is caused by an East West Modulator fault. That will give you an Hour Glass picture.
Check for dry joints around the line output stage and faulty driver transistors.
Hope this helps.

Hourglass picture. Panasonic CT-35G30T The picture is hour glassing from the sides. Starts to flicker back to normal after 1 to 2 hours. Getting progressively worse. Takes longer time to reach normal...

This is caused by bad solder connections in what's called the pincushion correction circuit. Some of the transistors get quite hot, and over time the solder connections to the TV circuit board become intermittent. When you tap the set, it causes them to make contact again so the picture is normal, but then it goes funny again. Resoldering the connections would take care of this problem. I would suggest calling a professional in to make the repair, which would cost far less than a replacement TV.

Hope this has been helpful, and thanks for using Fixya!

Rear projection - convex distortion / ghosting / expanding screen

The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony,Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Hour glass as picture

It is possible that your television needs to be degaussed. Gaussing occurs in televisions that have magnets, (usually speakers) placed to close to the unit. A degaussing coil can be purchased at a good electronic supply store. Simply follow the instructions that come with it. If this does not fix the problem, the television will require repair by a qualified service center.
