Question about Toshiba MW27FN1 27 in. TV/VCR/DVD Combo
We get these continuous (white) horizontal lines at the very top, about 10% of the CRT screen height. It detracts quite a bit from the quality of the picture. This is now for about 2 years.
Is there any adjustment for this I can access, or what is a possible cause/solution.
The product is MW27FN1C and was purchased July 2003.
I had the same problem on a 2003 Toshiba 32A13 TV. I replaced C407, 100 uF 35V and it fixed the lines. I noticed that this capacitor was mounted near the heatsink for the vertical output IC. I don't know if the heat aged the capacitor faster or not. The only cost was $9.99 for a 32A13 service manual download. I had a new capacitor in my misc parts box and it has a 105 degrees C rating.

Well that depends on 1) what have tried to fix it, have you tried a reset on the monitor or any other tools that are available on it. 2) have tried updating the drivers for the monitor or your graphics card. in lew of that there could be a component thats going to fail. Personally CRT's are out dated I would get a flat pannel if its affordable for you price wise you can get a good one very reasonably priced

It is C427 electrolytic cap 100uf @ 50V. I had same problem - just replaced it on 2003 Toshiba TV and all is back to normal. Cost $1.5CAD for the part, $16CAD for soldering iron, $2.5CAD for solder and $8CAD for solder ******. New cap is a bit larger then original - no issue.
