Please read this guide completely at least once before you attempt to fix your TV. You may also
want to print the document out. To do so click the "print" icon at the top of this article.
Unplug Power and all Cables
TV sets can hold a charge for a long time and can shock you even while unplugged if you are
not careful. It is strongly advised that you unplug your TV set from the wall at least 3 days
before attempting the fix. This will give the set some time to discharge some of the stored
electricity. Do not plug your TV back in until the repairs are completed.

www.PartStore.com
www.VanceBaldwin.com
The Philips part number is "312226832865'. Price is around $120.00 with shipping.
Update: 3/17/2009 - We have been informed by several customers that the HVG is now sold out
at Partstore and VanceBaldwin. The part is on back order with no estimated arrival date.
Another option is to contact Tri State Modules - Or PTS/Modulus.
They will rebuild your LSB board and replace the failed HVG.
If you decide to send them your board for repair you won't have to remvoe the HVG from the
board.

Slowly pull up on the first High Voltage Wire as shown in the picture. The wires are very tight atfirst because of the yellow clips. This is normal. Just increase the amount of upward pull forceon the wires until they pop out. An alternative method is to pop out the yellow plastic clips first.The problem with this method is sometimes the clips break as they are being removed and thebroken pieces get stuck in the old flyback.
If you place your other hand on the flyback it will provide more leverage.
Once the wire is removed touch it to the metal rack as shown in the photo. This will ground it outand drain the high voltage from the CRT/wires. You may or may not see a spark. The spark isthe stored voltages in the CRT tubes being discharged to ground. This will not damageanything. Once done you can safely handle the wires. Repeat the above steps for the remaining RED wires that are still connected to the High VolageGenerator.
You may want to touch the wires to the metal frame each time before you work on the set. Thiswill help insure that the voltages are drained and the wires are safe to handle.
Once you have safely discharged the HGV voltage from the CRT wires you can now remove therest of the cables from the circuit board.
Remove all the cables on the flyback board! Make sure you label them with a marker so thatyou know where to put them back!

On the board you will find several screws that will need to be removed also.
Note: One screw is hidden on the side of the flyback. Remove it also.
Once all the cables and screws are removed you are now ready to pop the circuit board out. To
do this push the black plastic clips back shown in the photo below. The clips are located on the
right hand side of the board. If the board will not move freely you have missed as screw. Check
again!
