Re: substitute flyback transformer 257805 causing skewed...

You have a pin cushion problem Checking the resistance to ground at DL04(K) found it was 8 ohms. Disconnecting the Pin modulator board at connector HL83 cleared the 8 ohms indicating the 8 ohms was caused by the Pin modulator board. Closer observation a capacitor CL85 a 6.8 mfd electrolytic, finds it to be vented and it was causing the 8 ohm short. Replacing HL85 pn 238292. This corrected the symptom.

Call a qualified technician. Obviously you dont have the training necessary to repair televisions.

I have sound but no picture on my tv sharp aquos 20 inch

if you mean have sound but no Pic.or no raster, horizontal section is the culprit. most problem is at the Horizontal output section that drives the Flyback transformer. Pull out that HV cap & test them to ground if there is some arc coming out. No arc means failed output section or the flyback transformer need to be replace..

There is a four inch black line on one side of the screen

I think your problem maybe picture tube.
next try
At first test for you flyback transformer and A.C. transformer out put voltage.
Best get it checked at your local repair shop.

When CRT TV's show only a white/bright line horizonatlly It is a failure of the flyback Transformer. Not all that costly to repair. Your old TV will probably still be working when all the latest plasmas and rear projections have been laid to rest. Fancy junk TV's dont get any better programs than those old reliable ones

Vertical lines in the picture

Hello, This require you opening the television and having an ohmmeter to work with. This is a vertical deflection problem - possibly a bad capacitor, bad connection, flyback/pumpup diode, or other component.
If the symptoms change - particularly if they become less severe - as the set warms up, a dried up electrolytic capacitor is most likely. If they get worse, it could be a bad semiconductor. Freeze spray or a heat gun may be useful in identifying the defective component.
It is often easiest to substitute a good capacitor for each electrolytic in the vertical output circuit. Look for bad connections (particularly to the deflection yoke), then consider replacing the vertical output IC or transistor(s).
A defective deflection yoke is also possible or in rare cases, a bad yoke damping resistor (e.g., 500 ohms, may be mounted on the yoke assembly itself).
Where there is a wide running vertically on the screen the likely causes could be a missing power supply voltage, defective vertical output IC, or a component associated with it is likely bad. A bad connection or blown fusable resistor may be the cause of a missing power supply voltage.
The following are NOT possible: CRT, flyback (except possibly where it's the source for a missing voltage but this is more likely just a bad solder connection at a flyback pin), tuner (except for the famous RCA/GE/Proscan or Sony models where the controller is at fault - see the sections on these specific brands). I am just trying to think of really expensive parts that cannot possibly be at fault :-).
Note that some movies or laser karaoke discs are recorded in 'letterbox' format which at first glance looks like a squashed vertical problem. However, the picture aspect ratio will be correct and turning up the brightness will reveal a perfectly normal raster above and below the picture.

No picture on tv

probably the Flyback is damaged is the high voltage transformer inside of the tv so you you need to take it to repair.

My hdtv picture is shrinking

flyback transformer or the equivalent IC needs to be changed ( some brands use and IC rather than a transformer)

Blue stripe down center of screen

Is this a tube television? If so, sounds like the flyback transformer is dead. Take it to the service depot FOR AN ESTIMATE!!!! It's probably cheaper to buy a new TV then repair the transformer.

No you can get a replacement from Suburban Electronics
Give the model number or if you can fine the CTC # they can get you a sub for around $18.00 plus SH
