Question about Projection Televisions

1 Answer

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.

Where is the flybac located in a rca hd52w59


Hello
Flyback transformer other wise called Line output transformer {LOT} is actually a step up transformer, which supplies extra high tension voltages to the guns. It can be locatee on the main printed circuit board. 2_7_2012_5_19_59_pm.jpgJust see the different views of the main board of your RCA TV. You can see the flyback transformer at the left top corner, look like a large black componen; with a ferrite "U" type core goes though it. It is the LOT. Line Output Transformer, otheriwse called as Flyback Transofrmer. OK.

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!

When turn on no picture and there is a high pitch buzz or frying. Then after a minute or two it will shut off by itself. Before thid happened the picture would come on slowly with a frying sound and then...


my first instinct in this is flyback transformer. or if it is three tube projector could be a high voltage splitter lines in picture sound like what is called retrace lines ... this is another indication of a possible bad flyback. high pitch sound is another sypmpton of a high voltage flyback transformer problem. WARNING televisions generate potental lethal charge. the device called flyback is used to generate several THOSAND volts. so be carefull if you take the back of any television. along with the flyback the horizontal output transistor possible could have failed. What type of tv is it? model

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.

The lead going from the flyback to that other device is a voltage divider or splitter as they're incorrectly referred to... To remove the leads press down firmly, twist and then pull up...

No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
