SOURCE: How do you fix a white horizontal line across top of Orion TV?

Hello eatkinson,

This denotes a problem with the vertical deflection circuit. This is more then likely the result of the vertical coupling capacitor failing. You will need the schematic diagram of the TV to find the capacitor in question. it is located between the vertical output stage and the vertical deflection winding of the yoke transformer. In addition check the continuity of the vertical winding of the yoke transformer this can cause the same problem. In any event the problem is that the vertical deflection signal is not getting to the yoke transformer or the yoke transformer is malfunctioning.

I hope this helps,

Thank you,

Your vertical IC has most likely failed

My orion tv model number sled4668w just went black no sound no picture


Two possible faults:
1. Fault to the main power supply regulator [SMPS] section circuit. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician.
2. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

Where is the fuse located on a M68LWF088X50 toshiba 27D46 27" tv?


If you remove the back cover of your tv try to follow the ac cord it will direct you to the fuse it is glass type. The ac cord is connected to the pcb just follow the line and you will find the fuse, but be sure to unplug the unit before removing the back cover of your unit, good day and best regards.

High pitched sound


The high-pitched squeal is from the power supply, usually because of failure of the horizontal output transistor, flyback transformer, or both. Without a specific model I can't give more definite information about part numbers or likely costs. But repairs of this type usually have parts costs in the 10 to 75 dollar range (depending on just which parts are bad, and where replacements come from) plus whatever labor costs the repairer charges.

Orion tv1934 19" Has Sound but no Picture


This could be an indication of the horizontal/High Voltage stage having a problem. You are going to have to take ths to a shop to have it fixed since the HV section can kill you if you do something wrong. There are however some checks you can do if you had a schematic.
