Shrinking picture Everything else is working fine on the tv, sound,color,inputs,etc...However the picture is starting to curve in from the sides like the shape of an hour glass. Is the tube shot? or is it something less costly?

Sounds like it's something more than the lamp. Double check all your connections...it might be something as simple as needing a new cord (RGB, HDMI, Component Video, etc) Does the problem exist with all inputs? (For example, DVD player, cable, etc) If the problem is only from ONE input source, try replacing that cable. If it's on all input sources...might be something more internal on your TV.
Good luck

try to play a DVD movies etc to see if the problem is on TV or the signal reception..

have you connected up correctly, have you selected correct EXTERNAL inputs, you do NOT "tune" a Channel to see picture, you choose external AV input on set. Must connect color to color. 3 for Composite Video AV.Yellow, Video, Red & White Audio. and 5 cables for Component 3 for Video , & 2 for Audio Blue, Green, Red, Also Red & White, Audio.

Comments: May 19, 2009- If your TV is shrinking and expanding you can get a repair kit from www.TvRepairKits.com for less than 50.00 May 22, 2009- Here are the most common symptoms and example photos of this problem.

• Video Shrinks and Expands - Over and Over - After warming up it typicaly works.
• After a few weeks the shrinking stops and you loose all video and audio.

SOLUTION

Its a fairly easy DIY job. Check the site www.TvRepairKits.com

Their kits include a photo instruction guide, parts, email/phone support, etc.

Still the convergece prob.The FL231 fuse near the FBT transformer it dead.The square fuses 3 rectangles fuses.One in the middle.

The pictures show the result of a bad terminal input board. You can verify this by checking the inputs. Connect devices to the board and try different inputs. You will most likely find this problem on the tuner and component input were your DVI and composite video will be ok. If it is the same on all inputs replace the A board

Check the site www.TvRepairkits.com . They have a kit to fix the shrinking and expanding video problem for this model.

I have the same Tv.. Repair tech said it was the deflection board. Cost $395.00 to repair.

Put the old chip back in...does the shrinking/expanding problem return? If so the new chip may be faulty. 

If the problem stays the same - no audio/video  - check your soldering, cables, etc. 

try not to do anything or open other program while its dvd shrinking or burning....bcoz dvd shrinking and burning occupies lot of memory cache and cpu usage.

GOOD DAY
