When you turn on set a lot of vertical scramble lines

need to access the ez menu to reset the parameters u will need a tech to fo this

Let me start at the beginning---Likely a bad main board in your case but nothing is sure in this type of set.

Main board controls all information to the front screen and communicates to various boards---There really is almost never a simple "that part is bad solution" as any board, the power supply, the main, etc can cause issues.

It can even be a issue with the front screen unit--called a display panel.

You might consider doing some research on the set by Google of the model number with "parts" to get an idea what is available and what potential parts cost might be.

If a main board is bad it will average from one to two hundred just for the part----if issue is the panel you are done--part if even available is more than set cost when new.

Let me know if you have questions.

What is the brand and model number (not indicated here) so I may try to give you an informed answer.

It does not look to be a problem with the TV. Check the receiver/set top box. The signal is not coming through properly &/or getting scrambled

dont factory reset the box at any time now redo your codes and make sure you save each line you put in if you dont save the lines you will receive nothing after you have imput both lines and saved them then turn the emu on you should be working ???now can you post the keys you have to help other people

your vertical hold is out on the tube. new tube is needed. cheaper to get a new flat panel tv.

Um...well when mine does that i unplug it and hold the power button for ten seconds and then plug it back in. Always works for me ;-) hope it works for u.

The problem could be in vertical blanking or video processor circuit. Also redish vertical lines may be from external RF or magnetic interference. Move set to new location away from appliances and speakers

STK392-560 STKS convergence CHIPs Replace both of them.

Mine looks like too, but the line running across isn't on my set, picture looks like this, and the sound works fine. I took the tuner board all the way out and turned the set on and it did the same thing, then I unplugged the top wire on the board next to the tuner board and the screen went black. plugged it back in and the screen came back with the scrambled picture. Anyone know why? Bad mainboard maybe? the left of the tuner board?
