My TX is about 14 year old. The picture alwasy was excellent until we had an exlectrical storm that knocked out the cable box to the TV. With a new cable box the TV works. The picture has excellent color,...

Try your cable box on a different tv set and also try connecting the cable directly into the t.v, if that makes no difference then your tv set may have a power supply problem that was caused by an a.c line surge during that storm.

The problem I am having is that my 32' Sony Wega kv32fs12 Trinitron television will work almost perfectly. Image color is beautiful. tuners seem to be working like a charm, but the screen has a slight...

Picture alignments made in servive menu.

pwr off + display + 5 + (+vol) + pwr on
You must do all within 1 second.
1&4 move thru settings, 6&3 chg value,
muting & enter saves chgs.

Your code access could differ.

In the menu note down all existing settings.
Make small adjustments and watch what happens if not in right direction reset that particular option to original value before you changed. In those menus you can bend, shift hor. and vert., etc.
But be warned only slight adjustments and write down start values before experimenting. Or you can get in to serious trouble.

Good secret service menues keep an access counter for manufacturer/dealer to see how many times it was used.

Picture broken and shrinking

You need to change your vertical IC, along with some capacitors around the vertical IC. Capacitor with value 220UF, 10uf, 470uf and finally 1000uf. Doing this will fix the set. Total cost under $40

Picture is now a thin horizontal line

now only visible in a thin horizontal line. first of all you reduce brightness to monimum. it just to protect your tv from crt demage. your problem is in horizontal output section as you have mentioned that week or so ago the right and left bottom edges of the picture began to move in like a sideways triangle filled with black so this sympton is due to hor. section problem. your flyback transformer or horizontal output might be defective. but remember check for power supply is ok from surge protector hope this will help.

TV picture has moved up

your pic. has shiffted vertically. very easy to fix. open the tv set, located the crt tube(end of the screen) there are four wires going down to the board that is compined in one socet. around that socet, you will find small knobs, look for vertical phase and you could adjust that pic. the adjusting should be done while the tv is on and has pic so be careful, you are dealing with a live electricity. good luck
