Question about Toshiba MW24FM1 24 in. TV/VCR/DVD Combo

2 Answers


While watching T.V. (toshiba 24" combo), the picture disappeared, and we were left with a thin vertical colored line on the black background screen. The VCR doesn't work, and the DVD had problems. The volume appears to be fine. The set is only 3 months old, so don't expect problems...Any suggestions? thanks for your help Frank

My television has sound but no picture. I can not program the television because I can not see the screen menu. I also have tried to change the antennae but this does nothing to the picture's reception.

Do you have any ideas to correct this problem. There is no warranty.

Yep it should still be under a warrantee so unhook it and go straght to your freindly authorized Toshiba reair center. If you bought it as is you have a line from side to side then you have a verticle sweep falure and could ber a fault of the verticle output ic or the b+ voltage going to that curcuit. Good Luck

While watching our set, after a few minutes, the picture on the screen condenses into a single line. You can stil hear the sound. Is the tube shot?

I would look for bad (cracked ring around pins) solder connections at the vertical output IC. Do not let play long with the line present or it will burn a trace across the face of the picture tube and you will never get it out.

One line horizontal onscreen

This is well known problem with the Toshiba line, the problem is in the vertical deflection circuits, it causes the picture to collapse to a flat white line, the vertical output ic and two to three capacitors need to be replaced to correct the issue.

There were lines at top of TV for sometime then today TV just shut off by it self and burning smell was apparent. Tried turning tv back on and just got souns and a bright line through center of TV. My...

you have a vertical problem . You will need the chip or IC. please check the voltage source to the chip(IC). Diode could be short. Ic had bad solder joints and there are 2 caps that will need to be replaced 100uf or 220 uf caps in the vertical circuits.

The picture went out. Still have sound.


CAUTION: To prevent damage to the CRT phosphors, immediately turn down the brightness so the line is just barely visible. If the user controls do not have enough range, you will have to locate and adjust the master brightness or screen/G2 pots.

A single horizontal line means that you have lost vertical deflection. High voltage is most likely fine since there is something on the screen.

This could be due to:

Dirty service switch contacts. There is often a small switch located inside on the main board or perhaps accessible from the back. This is used during setup to set the color background levels. (On some sets, this is located on the CRT neck board and may be a jumper plug or other means of selecting service mode - not an actual switch.)

When moved to the 'service' position, it kills vertical deflection and video to the CRT. If the switch somehow changed position or got dirty or corroded contacts, you will have this symptom. Flip the switch back and forth a couple of times. If there is some change, then replace, clean, resolder, or even bypass it as appropriate.

Bad connection to deflection yoke or other parts in vertical output circuit. Bad connections are common in TVs and monitors. Check around the pins of large components like transformers, power transistors and resistors, or connectors for hairline cracks in the solder. Reseat internal connectors. Check particularly around the connector to the deflection yoke on the CRT.

Bad vertical deflection IC or transistor. You will probably need the service manual for this and the following. However, if the vertical deflection is done with an IC, the ECG Semiconductor Master Substitution guide may have its pinout which may be enough to test it with a scope.

Other bad parts in vertical deflection circuit though there are not that many parts that would kill the deflection entirely.

Loss of power to vertical deflection circuits. Check for blown fusable resistors/fuses and bad connections.

Loss of vertical oscillator or vertical drive signals.

The most likely possibilities are in the deflection output stage or bad connections to the yoke.
Good luck..

Tv toshiba vertical problem

I had white lines 4" thick vertically for about a week, then one day powered the unit up and with in 3 seconds there was a loud pop from the rear or the unit. Any one know what needs to be replaced?

White horizontal lines at top of picture

Yes, definitely worth fixing. The problem lies in the vertical deflection voltage-doubler circuit. The usual fault is a single capacitor of 100uF/35V that has failed. It is normally connected to a rectifier diode right at the vertical IC. Replacing the capacitor (no more than USD4.00 in price) usually gets it working perfectly again. If you are finicky around technical work, then a reputable local repair shop in your locality should do it quickly for you and charge only labour.
