Tip

CRT projection TV lost vertical drive. Thin horizontal line only.


Your projection TV works but the only visible part is a thin horizontal line across the screen. What happened and how do you fix it?

Your problem is that you have no vertical drive, only a small horizontal line across the screen. In older projection TVs this is usually caused by broken solder joints in the area of the vertical IC and over the entire board. It could also be caused by a bad vertical IC. Let's approch this problem one step at a time.

Disconnect the power. Remove the back cover. Remove the board with the vertical IC which is usually the board with the high voltage transformer on it and it is usually on the right side of most TVs. You can also identify the proper board by looking for and following the wires from the yoke which is on the CRT neck. There should be a yellow, brown, green and red. The yellow and brown are the vertical wires.

Before removing any wires mark them with a sharpie or a label maker. Just make sure that you will be able to reassemble the unit without mixing up any wires.

Usually the board in question is on the right. It will be the one with the flyback on it. The flyback looks like a small cylinder with about 4 large wires coming off of it. They will be red rubber and flexible. One goes to each CRT.

You will need to remove the entire assembly to get to the underside of the boards to solder the unit or replace the vertical IC. Sometimes removing the restraints will allow enough room to flip the board over and do the work without removing all the connectors and removing the board.

Once the underside of the board is exposed, solder all connections on the boards. Be careful not to bridge any connections. Test the unit for proper operation.

If the unit still does not work properly replace the vertical IC. It usually begins with LA followed by 4 digits. It will be in the vicinity of the flyback probably towards the front of the board. The Ic will be attached to a large aluminim heat sink. Make sure that you do not bridge any of the circuits when soldering. Replace the IC, reassemble and test.

If things went well the unit should work ok.

Thanks for using FixYa and for the great rating. Please consider a testimonial. Thank you.

I am going to resolder the flyback, but what is? and where is the small signal board?? And would that need to be replaced or repaired?


I am attaching a picture of the flyback whicch is the large transformer which is on the far left side and has the thick red wire coming out its top. The small signal board is the large green board on the right side with all of the inputs on it. The small signal board is a sensitive board and requires professional tools (Chipper Check interface )to diagnose and repair. But the flybacks are famous for failing. the flyback is circled in the picslinteriors_15.jpg

Hello, I got a little problem and hopefully your expertise and knowledge can help me out. My TV is a 60" Philips Magnavox projection television model # 9P6040 C104 manufactured in 9/6/2000. Here is what...


Chances are , the Deflection Board, ( also called the Large Signal Board) is what is causing the problem. You would be able to replace it yourself being careful of where the High Voltage Wires go and also where the other plug connectors through out the board go when reinstalling them. You will have to locate all the 1/4 nut screws that secure the board in place. I estimate the Board to cost around 400.00 to 500.00.
This is a guess though. I wish you luck.
I hope this helps,

you need a new HV generator. The following site has them and they have a picture of it so you can see if thats the part youre referring to, I believe it is. Its listed under the flyback section and its called Phillips HV generator.

Hi again!!!


The RCA jacks should be near the signal board. The vertical will be on the same board as the Flyback which Is a large transformer with the large red wires coming out of it. You shold be able to remove the screws in the chassis and slide the chassis out and tip it up so you can see the under side of the boards.

Sylvania LC420SS8 HDTV. After 3 months, set won't turn on now. I did a 30 minute reset per manual instructions,still nothing.HELP. Tom.


If you are lucky, it's only a blown fuse. Some tv's this large have more than one fuse, so look real hard and find all fuses. If fuses are good, then about 95% of the time, when you have no picture/no sound, the problem is a bad H.O.T. This is a large transistor with three pins soldered into the main board and is very easy to find because it is connected to a metal "heat sink". Look for a large red or black wire coming from the pic tube down to the main circuit board (sometimes it's blue, but it's the only wire coming from the GLASS part of the tube to the board. This wire goes to about the largest component on the board called the "flyback transformer". It is usually black and is about 3 or 4 inches tall, 2 inches wide, and 2 inches thick. The h.o.t. will usually be located in the area of the "flyback". The h.o.t. will be screwed with one screw or clamped onto a large piece of metal (usually silver). This piece of metal is usually about 2 inces square and is about 1/8 of an inch thick and is mounted perpendicular to the main board. Imagine a slice of bread standing on one side rather than lying flat and this is what the heat sink looks like. Sometimes you will see several heat sinks with transistors screwed into them, but the one you are looking for will always be the largest transistor with three pins. Don't forget to unplug the tv before you begin and stay away from the large wire coming out of the tube going to the "flyback". Do NOT unplug this wire from the tube. It can shock you very badly EVEN WITH THE TV OFF FOR SEVERAL DAYS. Just be careful and go ahead and give this a try. You can do it, and this is probably going to fix your set. If not, then replace the flyback transformer. The H.O.T. is about $10 or $15 and the flyback can be from $30 to $80. It is possible that none of this will fix your set, but you have about a 95% chance that it will and with such a big and nice and relatively new set, I would give it a shot. Keever
