NEED TO ADJUST VERTICAL PICTURE


Replace capacitors CX2105 (35 volts 220 Mf), CX2110(35 volts 100Mf), C2104 (50 volts 1 Mf), resolder resistors RX2115, RX2116,R2118,R2119. You will need to also resolder the vertical IC. I think this IC location is IC 2200, its been sometime since I repaired this one.Do not short the pins together with excess solder. The values on the cap may not be exact. Please use the cap value that is removed (remove and replace one at a time). The locations will be correct! This will remove the horizontal lines or bars across the TV screen. You may as well replace capacitors in the horizontal deflection area. By now you have bad caps there. The locations and values are, CX3218 (160 volts 2.2Mf), CX3205 (16 volts at 100 Mf) CX3413 (50 volts 22 Mf) and CX3416 (25 volts 100Mf). Thanks for asking and show all hands of support.

Only get half a picture on my RCA television. only getting the bottom half of the picture


If you can locate the vertical IC (located on a heatsink) you will find this IC needs resoldering. This is a common problem with RCA TVs. The vertical IC is of a TDA series number. It will have seven pins. Examine very close and you will see cracks or rings around each pin. Resolder these, do not use excess solder or you will short the pins together. Inspect any and all solder grounds in this area, resolder as necessary. Thanks for asking and show all hands of support!

When I turn it on there is just a horizenal line. This is on a Mitsubishi cs 35 ax 1 35" from 1992


hi there, it seems you have problem with your VERTICAL IC, this is similar to all CRT I have repaired. horizontal lines in the middle huh! well the picture is deflected in the center of the screen. it shows your TV is oscillating. means it is good. the problem is that you cannot adjust the picture to occupy the whole monitor. By replacing the Vertical IC it will remedy the picture to view widely. the vertical IC has these many 8-10 pins and mounted on heat sink. Usually mine is serial with LA 7837. good luck on your troubleshooting, hope this help, please rate and vote.

No picture on tv screen


try resoldering the vertical output IC. sounds like the cRTs are blanking due to the vertical. If that doesnt help you may need a new IC. While youre there look for signs of the CRt leaking as often it leaks right onto the vertical output section real close to the IC.

The vertical output IC is most likely the cause. On a 27 inch TV the generic part number is AN5522 the location number ic IC561. Be careful of dangerous voltages within the TV powered on or off.
