'Fly Back Transformer' Arcing in 57'' Rear Projection TV

I've been given a very large 57'' Projection TV on wheels, when it's turned on there is a lot of arcing underneath the Fly Back Transformer for 2-3 seconds and after around 6 seconds the TV returns to standby mode (red light) without actually turning on sound/video.

I had approached a local TV repairer who wanted $80 just to drive up to my front door before even looking at the TV, so I quickly realised I'd need to do this myself. I'm proficient in repairing other electronics and have desoldered the transformer from the board, added insulation around the exposed terminals and resoldered it in there but the arcing is still occuring.

Would it be worth my while in purchasing a new Fly Back Transformer and fitting that? Or could the problem be elsewhere, overloading the transformer?

Any help would be very greatly appreciated.

Wow they are charging you alot for this repair my friend. Go to this link and you will see! The High Voltage transformer, also known as a flyback only cost 50.00 Bucks!http://www.partstore.com/ProductDetail.aspx?ProductSKU=2187762&ProductType=PART&ModelID=420798 I would get the part and let someone replace it If you have no soldering and or TV repair experience, as this is a dangerous place to be experimenting with if you do not know the safety issues involved.

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...

This transformer does not come with the hv lead,if the arch is coming from the side of the transformer,cut the side of the plug were it goes into the transformer and the lead will come out,there is no voltage stored on the hv lead after the set is unpluged for a few min.,the transformer you can get at any rca repair center.

SOURCE: Sony rear projection tv How to de-solder

I would suggest not to desolder that transformer until you are certain that is defective.
Try to change D6116 and D6301 first.
You can try Radio Shack or check this site.
Good Luck.

When I turn the tv on it has no pic and then turns itself off but would come on after about 5 times of turning it back on but now it just had sound and no pic.


It seems that your Pulse Width Modulation drive ic on power supply or high voltage section fails. This can be resolve by replacing the IC MCZ3001d that will be found on your power supply or at the high voltage section.(near Fly back transformer) If you have basics knowledge in electronics and soldering, you can easily fix it.

the static sound may be due to a defect in the high voltage circuits, IE Fly-back transformer or and voltage multiplier, posibly high voltage leads to the CRTs arching to ground, finally horizontal sweep circuits

TV wont turn on...red power button flashing


HI. this is a malfunctioning fly back transformer. it is connected directly to the picture tub, and is part of the main power sector as well. The fly back transformer can become covered with lint overtime. this will induce a very violent arcing effect that will usually blow the entire power sector.

Replacing the fly back and affected components will fix this issue.

Tv shuts off by itself then flashes a code 8 blinks


Eight blinks means, "High voltage error". The probable cause location listed is "T8005 is faulty (D board). T8005 is the fly-back transformer (FBT). or you can replace the full d-board
You may purchase the D board complete for $185.10

or send in for repair here

if one of the crt is shorted it can also cause this problem.
