Does the high voltage wire on my rca rear projection tv just pull out of the transformer so i can replace crt

If you pull the speaker grille and unscrew the service door behind it, you will find a sticker on the surrounding frame of where the hv splitter is(the one with 4 red thick wires), I think you are supposed to turn the wire you want out 5 times and pull, but I am not sure so look for that important note.

Ur high voltage transformer is dead,the FBT,the big block of plastic have red wire go to the video board.Also might have burns capacitors in the DM power suply board or deflection board it puffed up.

Ur high voltage is dead,the FBT.The flyback transformer is dead.The big black block of plastic with a wire with cap hook up to ur CRT(tv tube).Might
also ur DM power board,have burns capacitors,check for puff ups capacitors must also be replace as rebuild board.U know how to solder right?Tries thes websites for parts.Tv Repair World.com Shopjimmy.com Partstore.com or Ebay.com.

Hello butmommy03,

This is the procedure but first I must warn you. You are dealing with one of the most dangerous parts of a TV The High Voltage anode or the CRT and the flyback transformer. That being said this is what you have to do:

1) unplug the TV from the wall or power strip.

2) take the back of the TV, and find the High voltage trippler and using a screwdriver grounded by a clip-lead to the grounding strip touch it to the exposed metal of the input to the High Voltage trippler.

3) using a soldering iron de-solder and remove the wire from the HV trippler.

4) Once this is done, angle the chassis to expose the bottom of the Deflection board, if this is no possible you will have to remove the deflection board to get a look at the bottom, once this is done and you can view the bottom of the board using a soldering iron and a de-soldering pump you can remove the solder from around the pins of the flyback transformer about 10 pins in all. Then remove the screws that hold the flyback in place. this is the procedure you requested,

However again I must ask you not to do this yourself and to get a qualified TV technician to troubleshoot this TV for you.

Thank you,

It is usually large and black. Its the one with the rather thick red wire coming out of it. The other end of that wire either connects directly to the picture tube or into a distribution block which distributes the high voltage to the 3 picture tubes (guns) in projection TV's. Be aware that this transformer produces high voltage and can store voltage even when the set is unplugged. I hope this helps.

You have a bad high voltage transformer. It is the white square device about 3inch square with large red wire coming out. Must be replaced with RCA original NO GENERIC. Also the horizontal output transistor must be checked to see if it is good. Recommend honest qualified tv repairman

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...

humm.. could be a crt or a high voltage problem..flyback transformer or high voltage splitter... have a tech check it out for you.

Likely to have a bad high voltage transformer: white square thing with large red wire coming out and possible horizontal output transistor maybe C5148: on metal heat sink behind transformer. Must use original transformer Average cost $300.00 according to which repairman. Be sure picture was good before it went out!

remove solder from all pins and squeeze clips to remove...
