The wires don't come off the flyback. You have to take the front cover off where the speakers are. Trace them and unplug them.

Diagnosing and repair of TV High Voltage problems.


Your TV is dead or perhaps the turn on relay clicks and immediately clicks again, followed by your standby light blinking a specific code. For each TV the code is different. To find out your code google "(your brand name) error codes". This should return the listing of codes for your unit. Check the code to see if it is the high voltage section with the problem.

The hardest working section of any TV is the high voltage section. This does not apply to flat screens and DLPs only CRT projection units and conventional direct view units. The flyback get hot and is made of many windings of very thin wire which is only shellaced to insulate it. Over time the windings coating breaks down and the windings short together. This can happen in as little as several years. Once shorted there is less resistance and the current being pushed through the flyback increases. This overloads the Horizontal Output Transistor which gets hot and fails. This in turn causes the low voltage power supply to detect the overload and not allow the unit to start up, giving you the error code blinks.

The flyback is generally near the rear of the unit and is cylindrical with large rubber wire or wires if projection coming out of it and going to a rubber cup on the CRT or CRTs. Near the flyback will be a large heat sink with a large transistor mounted to it. With the set unplugged check the HOT with a DMM on diode scale for resistance. The leads of the HOT should be marked on the circuit board (C= collector, B=base,E=emittter). If the HOT has 0 resistance between all the leads it is shorted and you need to replace both it and the flyback.

You should be able to obtain both parts at http://www.encompass.com or http://www.shopjimmy.com . Unsolder both parts and remove from the board. When installing the new HOT be sure to clean off the heat sink and apply new heat sink compound available from the parts supplier. The flyback also will have two additional wires to remove and replace. One goes to the CRT board and may plug into a plastic box on the CRT jack or be soldered into the board depending on the model. This process should be self explanatory if you study it a while.

Depending on whether you have a projection TV or a Direct View TV the procedure is a little different. I will describe the procedure for a direct view TV first.

The 2nd anode lead (large red rubber wire going to the CRT) is plugged into the CRT and may have 48 kilo volts on it! Discharge the potential to the ground strap (bare wire going around the CRT) using an insulated screwdriver and a wire with gator clips on each end. If the CRT was storing power there will be a spark and loud snap when you make contact. Once discharged the tube is safe. Pull back the rubber boot and remove the wire from the hole in the tube. Install the new flyback wire. Solder the new flyback to the board reassemble everything and turn on. If you were successful the unit will start. You will need to set the focus and screen drive using the two potentiometers on the back of the flyback. Top is focus, bottom screen drive. Turn up the screen drive to get a picture. Tune to a channel with text. Turn focus to get the sharpest image. Tune to a channel which has both black and white in large amounts. Turn up screen drive until the black just begins to light up or starts looking gray then back it off slightly and you should be done with the unit. Be careful while adjusting the flyback as the set will have lethal voltages in it.

Now for the flyback on a projection TV. It will have 4 large rubber wires coming out of it. If the new one came with wires they should be removed at the HV divider block (located at the front of the set normally, just follow the wires to their end) if not they should be removed at the flyback. To remove at the flyback, which is the most common hookup, slide the rubber boot off the post and using needle nose pliers pry the cable out. It should have a bare end which connects to a clip at the bottom of the new unit. Do them one at a time to avoid getting them wrong. When done you may have to adjust the focus and screen drive but it will be on a separate box called the HV divider block usually near the front of the unit behind the grill. Same process as listed above for the direct view set. If your unit still does not run you may also have to replace the HV divider block. All safety rules apply here also.

That should conclude the repair and if successful your set will work. If the unit still does not work go to my tip on troubleshooting at http://www.fixya.com/support/r4425277-basic_direct_view_tv_troubleshooting which explains the basic troubleshooting method to find any problems in standard televisions.

Thanks for using FixYa.

Wires going to flyback transfomer


Wires going into the flyback are not removable but are integral to the flyback. The three wires comming out the flyback are the thick red one (anode button) which attaches to the tube is removed by pinching the button to release the clips on the tube. The other wire probably white is removed by unsoldering it from the small board on the neck of the tube and the 3rd and last wire is probably black, this is the one you may have your issue. To remove this wire, you must disassemble the tube socket..look for two tabs..pry open gently and seperate. Then with a small jewelers you'll be able to release the black wire..hope this helps.

You will need some solder wick to remove the old solder. You need to heat up the old sloder with a solder iron and while its molten touch the solder wick to the solder and the wick will absorb the old solder. You will need to keep trimming the solder wick end so it will keep soaking up the old solder. Do that to all remaining pins on the flyback. The replacement flyback will not come with the high voltage wire attached so you will need to remove the wires from the flyback. This is accomplished by twisting the wire 90 degrees while exerting upward pressure. Instalation is the reverse of removal. Let me know if you need additional assistance.

Try removing the back panel and try to power up the set and see if you can determine if the popping sound is coming from the flyback, in case your not sure what a flyback is it has a large red wire coming out of the top of it. If thats where its coming from let me know as you may need a flyback.

Please help


sorry about that my new email is Willie@FORDTV.COM These are some of the hardest cables to remove. the black wire will come out but you have to pull straight up and with some force. with steady force not quick jerck or you can break the wire. the big red wire usally has a clip gromet under the boot slide the rubber boot up the wire. remove this gromet is difficut. i usally break about 75percent of the one i try to remove. some technicians say freeze spray helps..i never use it the groment holds the wire in the hole there are two slots on the side you that push in.. question did the new flyback on the board have a groment..just in case break the old one?
