Question about RCA F19240GY 19" TV

Open Question

Picture scrambled periodically

Hello, The picture in my RCA TV is getting scrambled time to time in random parts of the screen. It looks like some portion of the screen is getting horizontal deflection to the right. It appears randomly in different places. Hitting the TV helps to resolve the problem and it may work Ok for 1 minute or for 1 hour then it gets scrambled again. Also periodical thin white diagonal strips appear and disappear with random spacing. Thank you.

The text box function of the closed captioning is on. There may be a button on the remote to turn it off or you may have to go into the menu to do it.

Get an ESR meter and check all the electrolytic capacitors in the set! I am sure you will find many decoupler and coupling capacitors that are on the edge or too high in ESR.

SOURCE: TV turns off after short period off time

I have this problem as well-have to keep the house cold enough to keep it on.  I also have a box fan blowing into the right side vents (the side OPPOSITE the built-in dvd player).  It helps a lot to have the fan there, but if you put the fan on the left side vents you will have much more frequent shut downs.

It could possibly be a protection circuit in your tv that protects it if something is not functioning properly. from what is described, it could be anything from overheating to even a bad power supply! I would have someone look at it. Good Luck!

SOURCE: RCA 27 in has white horizontal line going through the middle

this symptons is caused by a breakdown in the vertical deflection circuit. hence, the trouble may be in the vertical oscillator, amplifier or output circuit. in most modern tv the vertical ic is usually composed of these said circuit inside. the ic have many pins, standing on a heat sink and smaller in size. try to check also the capacitors surrounding it. sometimes leaky capacitor may cause this problem. good luck!

My RCA 27V530T has sound bu t no picture. Could this just be the picture tube?

There are many reasons for this fault, and picture tube is one amoung them; but a very rare case. Normally, for all picture tube based TVs, short in the windings or the LOT [Line Output Transforemer] is a normal case. If this occures, there will be no picture or screen at all, as all voltages to the picture tube, including its filament voltage are derived from this transformer. Check this first. If it has faulty, the drive transistor [horizontal output transistor] will also will get leakey. First check this transistor. If found leakey, replace it with same type and number. Switch ON the set for a short period of time, say 5 seconds or so, and check the heat of the replaced transitor by touch, after unpluging the set from AC mains. It can be some heat with this transisotr, but it should not overheat. If it overheats, make sure that the LOT said above is damaged, and should be replaced with same type and number. All these components can be bought from open electronic spare part selling shops at your town. You can do this work by yourself at home, provided must have sufficiant testing and soldering equipments; and a sound knoledge in electronics.
If you don't ahve these, get the TV repaired by any experienced service technician, of by the authorised service center for RCA at your town. OK.

White lines across tv screen

Without seeing the lines I can't be sure what your set has wrong, but here are a some possibilities:

If the lines are lines are confined to the top inch or two of the screen and the picture looks otherwise normal, the trouble is bad capacitors in the vertical output circuit. Fixable by replacing the bad parts.

If diagonal lines are across the entire face of the picture tube and the picture looks washed out, the trouble is often a bad capacitor on the 200-volt line to the picture tube. This may be on the main circuit board near the horizontal output transformer, or on the small circuit board plugged onto the end of the picture tube. Again, replacing the bad capacitor can fix this.

If your TV is actually an RCA, someone may have bumped a rear-panel adjustment. On the back of the TV near the bottom right are two small knobs. RCA left these adjustments exposed inside of putting them inside the set like other manufacturers. These sometimes get bumped if someone was behind the set cleaning, or if a pet got back there and hit them with a tail. The top knob adjusts focus, and the bottom knob adjusts something called G2 or screen voltage. If this gets turned up too high it can cause the faded picture and diagonal white lines. Turn the adjustment down until a black screen looks black instead of gray.

A bad picture tube or horizontal output transformer can also cause lines through the picture. If this is the case with your set, it's time for a new TV. The transformer is relatively inexpensive but labor costs aren't, and the repair bill may exceed $200. If the tube is bad, there's no point even considering repair. The tube cost alone exceeds the cost of new TV.

Hopefully your lines are easy and cheap to fix. Good luck, and thanks for using Fixya!

Picture tube RCA F27676BC TV from time to time suddenly goes to almost a full bright white screen then starts to flicker randomly. Could it be a driver chip on PCB?

no. possible loose solder connection but i believe it is sediment in neck of picture tube(crt) try while tv is on with the back off, tap tap tap the neck of crt with plastic side of screwdriver. hit it hard but dont break it. this will knock loose the sediments in the crt. fixed!

No picture or anything

If your model # is 32V420T, your TV probably has a bad

RCA CTC203 no red colour

Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.

using a dmm check the resistors on the kine board. the small board on the back of the picture tube. you sould find an open resistor. if i remember correctly, if looking at the back it would be on the bottom of the board & about 180k ohm. if you have a difficult time finding it, look for the same type/color of parts on the small board to make comparrisons. between parts. you sould have 3 of most parts, one for each color. good luck.

Static on picture

The more you hit the set and wait to get this problem fixed ,the more its gonna cost ya. Your problem is a very common one for RCA. Whats happening is theres several grounds around the tuner sheilds and tuner covers that are intrmittanly going bad because of the differant types of materials they used for the sheilds and covers , so the metals are all reacting differantly to the solder ing in the set. This set if not fixed right away will cause the eeprom to go bad and or the vertical swwep Ic to fail. The repair shouldnt cost more then 125 to 175 bucks or your getting ripped off!! Happens all the time . Good Luck
