Question about Toshiba 27AF44 27" TV

1 Answer

Horzontal lines across top 2" of screen on both my Toshiba TVs?

This just occurred past 3 mos. - first one TV, then the other started with the horizontal lines. Newest was purchased 2004. Cablevision just left my house and Cablevision claims both my TV tubes are "going" - that I need two new TV's. If it was just one TV, I wouldn't question this - however, what are the odds both TV's (both Toshiba's) would have problems simultaneously. Has anyone heard of this? Hey, if they're on their way out, fine; but just curious if anyone else has had similar issues.
Thanks so much for your assistance!

    Thank you so much for your response - we contacted Toshiba directly - they also recommended a tech. should come and look at the sets and also supplied phone number to find tech. in my area.

    I'm still shocked it happened simultaneously!

    Thanks again!

It's NOT the "tubes" (the glass picture tube you view) this is 90% of the time a capacitor in the vertical circuitry. A good TV tech can find and fix this issue for probably a little less than $100 per set at the most.

    the simultaneous failures are due to a design flaw. Tell the tech that if the problem is due to failing electrolytic capacitors to make sure to install quality 105 degree celcius quality capacitors not the standard 85 degree ones! When the give you the old parts back (and a good tech always will) I bet you will see it say 85degrees right on the label.



    If you make this request, the tech will think you are so smart that you are only hiring him because you don't have time to do the job yourself and so should be quite honest with you I bet!!!!! ;) He might even give you a quantity discount since the problem is almost sure the same part in both sets.

This is usually caused by bad capacitors in the vertical circuit. If you have an electronics background you should be able to find the defective ones with an ESR tester .

Black line problems


Some components in the vertical deflection amp have been going out of spec with age.

The set may no longer be worth to spend money to service it because of its age. However, if you wanted to invest the money, the set is serviceable. Considering its age, the CRT may be soft, and there are many other older components that can soon fail.

I would be considering a new set.

2. Bad Screen voltage Capacitor.

White horzontal lines on the top of screen


Typical symptom of a faulty screen voltage capacitor. You'd need a schematic to locate the cap and then change it out.

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.
