No vertical is always an affordable fix.
- failed (dried out) electrolytic caps in the vertical circuit
- failed vertical IC
- failed power to the vertical circuit.
Hope Ya Fix It

No horizontal and vertical deflection available:- audio OK


Check its horizontal output stage circuit. Replace damaged component/s. Vertical output stage gets its working voltage from the horizontal output transformer. If you want to get vertical deflection, this transformer, otherwise known as {LOT] should work to produce the supply voltage to vertical output stage.

Horizontal ine in CRT tv


Failure of the horzontal linerity coil, possible dry soldering on the board of the components- resistors and capcitors- in the horizontal coil circuit . Also failure of the deflection coil- YOKE- in the crt. So check the coils and the circuit around this section as the rest of circuit seems OK.

Toshiba Model 53HX71: Bottom half of screen and sound is fine; top half of screen has collapsed to a horizontal line in the middle of the screen. Repairman I spoke to briefly said it probably won't be...


Hello
Your TV has vertcal scanning problem. All picture tube based TVs have, both vertical and horizontal scan to spread the picture to entire screen. When vertical scan section meets with a fault, the picture will collapse horizontally and fi horizontal scan section has a troubl, picture will collapse vertically. Your TV s fault , we technically say, to be vertical foldover. This is due to the vertical output section, a circuit part, inside the circuit board of your TV.
To rectify this fault you must open your TV. Unplugh it from the power socket, and open it. Locate the vertical output section, which is easy to do. Look at the deflection yoke, the coil fitted on the neck of the picture tube, and you will see four wires from it going to the main circuit board. Out of which, two will be thick, normally red and blue in colour, connected to the opposite direction on the deflection yoke, and the other two will be thin. follow the two thin wires, said later, and you will reach to a plug in point on the printed circuit board.
Before doing anything, just look at the soldering of that section carefully for any loose soldering, or bad soldering. Usually, the components in the vertical output section will get heated during working, and ahve a cahnce to get loose contacted soldering joints. Just resolder all the suspected points by applying a little more solder, and see the effect. If thi doesn't help, check the IC used in that section for trouble. Some capacitors will be there in this section, will get dried as aging, replace them first, as they are ver few in numbers, When replacing capacitors, note their polarity, as electrolytic capacitors have both positive and negative terminals like torch cells. Before replacing the vertical IC, replace all the capacitors, especially, two or three large capacitors on that section. Just do these and if you want any more assistance feel free to contact me through Fixya. OK

Unit has sound, no vertical deflection. caps and output ic ok. have b+ to output. nothing at pin 2 of output ic.


If there's an audio,,it might be the defective Vertical IC...but check first if there's 24v-26vdc supply coming from FBT going to Vcc of Vertical IC.

If there's no Audio,and only white horizontal line in the screen,check the Vertical out of Jungle IC.

Good luck!

H line problem


I think you are describing 'no vertical deflection.' If all you have on the screen is a single horizontal line, the vertical deflection circuit (or IC) has died. Unless you have service documentation on hand, I can't give a part number to replace but this is typically not an expensive failure and if the set was OK before, it is worth having repaired.

It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.
Good Luck

Had horizontal Lines replaced now have error 21 xray circuit


White horizontal line (no vertical deflection)
Check / replace R548, R549
Sound but no picture except for a couple of horizontal colour lines
Replaced the frame chip TDA8356, set now ok
Severe vertical jitter on picture, horizontal sides of picture ragged
Replacing the TDA4950 cured the fault
White line down centre of screen (top to bottom}
Replace C805

Set starts, horizontal and vertical deflection work, HT ok, crt heaters ok, but no sound or picture
I turned the G2 voltage up and noticed a white screen with flyback lines, frame ok. I detected two badly soldered double diode rectifiers in the secondary part of the power supply ! I checked all other joints, and everything was ok !! success
White horizontal line (no vertical deflection)
