Question about Televison & Video

Flyback transformer? i found 5.5v on the the abl line off the flyback transformer. the manual states it should be -2.2v. does this mean the flyback transformer is bad, or could there be something downstream the issue causing this to be high? do you have any advice to help me troubleshoot the abl circuit and flyback? any advice would be appreciated. (I believe this is the reason I have green bleeding into the highlights of images) thanks

Its either the flyback or a regulator. But i would need the model number of your set in order to know for sure. Please reply to this same post with your model number.

We replaced the transformer for our RCA F27650. It was sparking and now it is not, but now the screen won't turn on. It is just black. We hookd all the wires up like they were. we can hear sound, but...


Hello
Along with the flyback transofrmer, its horizontal output transistor also must be replaced. I don't know whether you have replaced it or not. If not, replace it too. It can be located very near to the flyback transformer, a three terminal component, black in colour, usually screwed to a metal heatsink. Then switch on the TV and measure the video output voltage at the video output card pluged directly to the picture tube neck. The collector of the video aoutput transistors must come around 145VDC. If it also is there, advance the screen control on the flyback transformer to get a raster. If that voltage is not there, it means that the flyback transformer is not working, and horizontal oscillator stage should be checked for oscillation, check the lined drive transformer for its primary winding open, Check the entire horizontal oscillator section. The collector point of the line drive transistor, the transistor that drives the line drive transformer, a small transformer soldered diretly to the printed circuit board; should be checked with frequency meter. The frequency at that point should come around 15525HZ approx: OK.

RCA HD52W59 flyback transformer


your model uses the 270125 flyback if both wires are red. If one is red and the other black then you have the 259296 flyback.

1.Dead on switch but red power LED comes on. Previous to this intermittent fault with flyback lines then red screen then white screen and loss of sound.


Flyback transformer is very likely bad. Also the most common in these sets as well. The transformer provides and regulates the power. There should be a label on your set that has the DC voltage output rating. You can use a voltmeter and measure the rating your flyback is putting out and see if they are the same.

Cannot Find Flyback Transformer 60PP9202/17F


Contact Philips directly. They should be able to get you the part, even if they have to get it from another repair shops. Many repair shops purchase their parts from factory authorized distributors, not from the manufacturer. The flyback transformer powers the tube-it can be extremely dangerous to work on-EVEN with the tv off, they contain a lot of power somethjing like 50,000 to 150,00 volts. It is not fun getting shocked by one of these as many techs have been knocked unconcious by them. If you do not know the proper procedure to discharge a flyback then leave it alone!

700e Lg crt monitor problam power on eht on but not display


The normal crt monitor have a demo display when you unplug the vga cable to PC like this image below.. fd6b6b9.jpg
Note:
If the crt monitor green LED light steady and heater beam have light, the horinzontal and High Voltage supplied to tube is completely good. If you encountered this problem just focus on video section of crt monitor. But before you start... find the flyback transformer behind this they have two controls screen & focus. After you found it plugin the monitor use plastic precision or small screw philip driver for safety to high voltage at horizontal area choose screen control rotate it to clockwise direction follow this....
5b5166c.jpg If the display responses or from dim to lighter 100% you have a problem to ABL find this at the bottom of horinzontal section near at flyback transformer pins trace the line of ABL for dried solder, open resistor if nothing happen find the Video IC at chroma section and replace it. follow this...

Panasonic TV has blank screen with retrace line


retrace lines usually means screen voltage is to high . that could mean bad picture tube.or flyback.

But there is something you could try. Be careful high voltage.on the back on the flyback transformer there to adjustments screen voltage and and focus go slightly counter clockwise or in your case clockwise that pot addustment will make it darker or lighter.If this does not fix it you have a flyback oy tue problem.
I hope this helps thanks doctor video leadingedgeelectronics 1987

POLAROID TTM2401


Check components around the flyback transformer. Especially small value resistors and diodes. Also check the solder joints on the flyback transformer. Please be safe and unplug set when checking parts, also discharge caps or wait a while after unplugging.

Flyback transformer on television


Single white line across screen mean a vertical colapse. So you will need the vertical output and maybe a cap around 100uf@50v.
