Question about RCA 24F501TDV 24" TV

1 Answer

Hoizontal Bar across RCA Model 24F501TDV Color TV

When I first turn on the TV...There is a horizontal bar across the top of the screen (about 6-8 inches wide). There is video in the bar...but appears like the interlace lines are on top of each other. After about 10 minutes the bar shrinks to about 1 inch in size and then looks like vertical foldover.

You may need to change your resolution on tv settings as well as cable or satelite settings if you have one of those

White horizontal lines on top of screen


Replace all the electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them. Replace the at one time. The fault you see is technically called " vertical retrace lies".

Just got this tv from friend. has no remote. screen is black. sound is good. when you push menu button, white line goes across horizontally the screen.


The horizontal line indicates the vertical deflection circuit is not working. Either the set is stuck in service mode for adjusting color (turns off vertical), or the deflection circuit has failed.

Some RCA TV sets have a "Service" switch in the back, down near the bottom of the set. Most of the newer sets use a combination of remote control and front panel buttons to get into service mode, and that can be turned off by unplugging the set and plugging it back in. Try looking for the mechanically operated service switch in the back first.

RCA TV has nothing but horizontal line


If you look closely at that line, you can probably see it shift color; this is caused by the video that is now compressed in height. The failed circuit is call a vertical amplifier and there are so many ways to accomplish this I can't give you a part number to look for inside but it should not be an expensive repair; parts and labor should be around $50 to $75 US.
If you have a service shop for standard TVs in your area, call them with the brand and model number and tell them you were told that the vertical amplifier (or section) has failed. They should be able to give you a fairly accurate quote.
If you were still satisfied with brightness and color, it isn't a bad idea to have it done since it is unlikely that ANY new, flat panel set will live even half as long as your RCA.

I have white horizontal lines about 2 inches at top of my tv


You have some bad grounds on the Vertical IC. In addition to this, in the immediate area of this Vertical IC, are a few bad capacitors. Look for this IC mounted on a large heatsink. It may have seven pins . I cannot remember for sure. I have not worked on this particular TV, so I cannot give you specific locations. But I assure the problem is in this area! If you have some electrical experience you can pull this board out. In this case only the caps need replaced and the IC resoldered. Good Luck and thank you for asking. If you have anymore questions, visit me...Thanks Again! Your south of the border tech!

My TX is about 14 year old. The picture alwasy was excellent until we had an exlectrical storm that knocked out the cable box to the TV. With a new cable box the TV works. The picture has excellent color,...


Try your cable box on a different tv set and also try connecting the cable directly into the t.v, if that makes no difference then your tv set may have a power supply problem that was caused by an a.c line surge during that storm.
