Question about Standard (CRT) Televisions
The problem is I have a horizonal line; No vertical deflection.
I have already replaced the vertical output device and no change.
SOURCE: 20 inch T.V.
I have had past experience some years ago with new or fairly new TVs which had vertical deflection failure. I suggest Checking all coupling capacitors on the circuit board around the vertical deflection circuits. One way to check is to turn the set on and slightly warp the circuit board and see if the deflection restores. I have found bad solder joins in several sets which lost the Vert. deflection and was simply repaired by re soldering the connections.

If the main IC is not putting out a vertical drive signal then the vertical output will not do anything and therefore will not be damaged. What exactly do you mean by the set "literally eats deflection IC's"? What is the number on the vertical output IC? I will bet that your pump-up cap or pump-up diode is defective.

You might try substituting a new fuse. Be sure the replacement has the same rating. You may have a short in your power supply and depending on the type of supply the supply may not start up if it has overload protection. Stargazer

It isn't a transistor, It will be an I.C. with a part number that probably starts with an LA_ _ _ _ . It will be on a heat sink and be in the vicinity of the connector going up to the yoke. Try replacing that. But first, check all the electrolytic caps around it for testing dry (sorry - takes a special meter to do it in circuit) or just replace them. May have lost power to the I.C. as well. Look the I.C. up in the free NTE crossreference at nte.com get a diagram of its pinout to find what pins the power and outputs are on.

It is usually located near the power supply section. unplug the TV, open the back of the TV and look for a small glass cylinder with two metallic ends. This will be the fuse, now to check it do a visual inspection and you should see a clear cylinder with no internal dark smuges (good) has smudges (bad). Then if you have an ohmmeter set it to the 1xR setting and measure the fuse ends it should read 0 ohms if the fuse is good and no reading if the fuse is bad.
I hope this helps
