Problem on the screen, shows only small part of picture

RCA Television Manu. Oct 2002
Model F27442

Suddenly the screen shows only a horizontal band about 3-4'' in diameter. Above this are horizontal lines, almost like a venetian blind over screen. I cannot find anywhere on the TV any screen adjustments. Since I can't see the screen properly, the menu button is unuseable. What can I do?

My friend friend i recommend to find a technician and let the technician fx the problem. Your TV has expenriencing Horizontal IC problem and the only way to fix this is to find that IC or integrated Chips then install new Horizontal IC to enable the control setting and reset your default setting. Also if you cannot find technician in your area then you can ship your TV to the supplier for Technical assistance in actual fixing. The advantage of having a technician or Actual Technical support is that they can personaly find the problem and fix other problem aside from the current problem then it fix the problem in less time consumption.
Hope this solution helps address your problem.If you need more assistance just reply to this post.
Thanks

I have RCA Model # f27227em and it won't come back on. Do this TV has a reset button or switch on it. What's causing TV not to come back on.


Several things may be bad. First bad capacitors can prevent this set from coming on. A bad flyback and a bad Horizontal Transistor may destroy your TV. One of the most common problems with this TV was sound and no picture. This fix required the removal of a coil in front of the Horizontal transistor. Remove the coil and clean the legs,and the surface on the board where you will resolder! Hope this helps with your solution. Thanks for asking and show a few hands of support!

Coil L14401 needs removed and the ends scraped clean. Clean the board where the coil was removed and reinsert this coil and resolder. Your TV will be back as as good as new! This coil is located near the Horizontal Output transistor!

Tv problem


The F27442 uses the CTC203 series chassis and that symptom is very common. If the horizontal output is shorted you MUST resolder the coil in series with the base of that transistor and the pins of the small horizontal drive transformer. When they have been properly resoldered you can put in a new original horizontal output transistor. If the output transistor shorts out again then your flyback (high voltage) transformer is shorted and needs to be replaced.

Check for shorted base-collector junction on horizontal output transistor designator Q14401. Also coil L14401 going to base of transistor needs to be desoldered, scrape ends, resoldered. If horizontal transistor is shorted, real possible flyback transformer bad.
