Vertical foldover The TV picture has a foldover at the top. The raster is full height, but the top two inches of the picture is folded upside down onto the rest of the picture. This has been going on about a month, and has gradually gotten worse. I can't find a service manual for this TV,

Hi and welcome to FixYa,

Offhand, on most TVs, your described issue indicates that the Pump Up capacitor has slowly leaked and/or nearing end of life (dried up). This capacitor would be located very very near the Vertical Deflection IC and would be the biggest of the bunch of capacitor within that immediate area.

Rather an inexpensive component, should not take a couple of minutes to replace. What would be more challenging is identifying/locating it and getting access to the solder joints underneath the PCB (printed circuit board). Should look like image below (not necessarily same value/specs).

Good luck and Thank you for using FixYa.

This is a problem in the certical circuit. A capacitor has become defective. It will likely be a 100ufd cap in the 35V range. Look for the vertical IC which is a small flat IC attached to a heatsink that will be marked LA7837 or something similar. Note the designation on the board for that IC (eg. IC301). The cap in question will be marked C3xx indicating that it is in the same circuit and should be close to the IC. I'll try to locate the schematic on this to get you the specific number.

Keep us posted.

A black line (about 2 inches wide) appears at the top of the screen with this amount of the picture looking like it is folded down translucently over the remaining picture. What's up?


Hello
Your TV has vertical fold problem. Just check all the electrolytic capacitors. On checking, most of them may look good. But on circuit, when energised, will show problems. So it is best to replace all of them once and check. Please check the electrolytic capacitor connected to the vertical power supply [usually comes from the secondary supply section of the Line Output Transformer], first, and replce it. It may be a 1500Mfd or 2200mfd. Check it first by replacing a new one. In most foldover cases, this service will solve the problem. gopakumarg43@ymail.com

I have 32 inch toshiba analog tv with builtin dvd and vhs, the top of the screen is like rollong over , like when words scroll across they are upside down at top of screen? or the top of someones head...


The Vertical circuit is going out. A leaky capacitor is causing timeing problems with the vertical height and retrace. Adjustments may seem to help, but they will noot last as the part is failing and will get worse and worse until it goes out all together.

It will need to be repaired by a qualified Tech.

Two inches at top is black


That's called vertical foldover - you need a new vertical output sweep capacitor. Might be worth tossing and replacing.

Folddover at top of picture about an inch from top


Replace cap. 2465 and cap. 2561. That should take care of it unless the vertical transistors are bad or there are other bad caps.

Vertical Height Problem


I work with electronics, too, and I don't have the exact schematics, but I would say that you are on the right track with thinking the capacitor is going bad. What put onto that idea how you mentioned that it had gotten worse over time. I don't think that it's the veritcal driver.

DS25390 Verticle foldover


If you have a picture but the top is folded over, your vertical IC is probably good and you need to replace the pump-up capacitor next to the IC. When the pump-up cap (typically a 47 or 100uF 35V cap) is open then the picture will have white lines and foldover at the top. The typical vertical output IC is the LA7838, but I am not familiar with exactly which output IC your set uses.
