Changing CCF tubes in a TV

Hi,
I have a 36" JVC LT-Z32S2 LCD flatscreen TV which is 5 yrs old.
It looks like the lower CFF tube(s)has gone in that the lower half of the screen is darker than the top half.
Whilst still watchable it does make some programs less enjoyable.
Can I simply change the tube for a new one without incuring mega cost from a TV repair shop?

I don't work on JVC, but i know that none of the other brands i work on have the bulbs, the lcd panel in all cases is a complete package that is not serviceable and must be replaced as a unit. I think this stinks too, because i could solve allot of my customers issues if i could just replace a defective bulb. I asked one of the manufacturers about this and i got a surprising answer, they said that they can't sell that part because the "manufacturer" will not sell them the part, - what they are trying to tell me is that most of them purchase there panels from another manufacturer in china, and china does not supply replacement parts for the panels. They also said it would be cheaper for them to do in warranty repairs if they would offer panel parts but as far as i am aware most of the Chinese manufacturers refuse. There is also an electronic circuit board located on the back of the panel called a t-con this board in most cases is not available either and requires a panel replacement to fix a problem with an easily replaceable board. In some cases the t-con is now available but that underscores the new idea in tv repair. Instead of replacing the small component like a cap, resistor or ic, we now must replace boards and panels which makes the repair not cost effective outside of the warranty.

If you have a flat screen LCD TV then there is NO color tube. Somebody is blowing smoke. Don't deal with him. The main board in conjunction with the screen controller board are the places to look.

Thomson colour tube is gone


If you had mentioned that the picture tube is defective and confirmed it is a serious fault. You can rejenuvate the picture tube with a gun tester and short remover.This is not a confirmed solution but you can take a last try. Changing the picture tube is not recommendable for an old set and I would like you to go for a new Tv which will work out cheaper and gauranteed.
Hope you decide sensibly. Good day

I have a Sony Trinitron about 7 yrs old. The picture is flashing on and off. The sound is constant. The flashing was happening about the first 5-10 minutes after turning it on then it would stop. Now its...


Hi there
Sorry to be the one to have tell you that but yes your tube is dying.
In sony tv`s the video(picture) is off until the tube has warmed up and now that it is getting weaker it has difficulty reaching the point where it will bring out the video.
If you want to clear that problem for a while , you can open the back of the set.
You will see a round transformer(flyback) with two controls on it and a thick red wire that connects to the back of the tube.
With the tv on turn the lower control up slowly , you`ll see the brilliance go up and that will help with the flashing picture for a while.
If you see lines across the picture when you adjust that control it is because you have reach the max the tube can take , just turn it back down until they disappear .
Hope this help have fun

My acer X193w+ screen turns pink. What is causing


laurie515, Gee, I hope it's a 'pretty pink' colour. Do you really mean that What was once WHITE or VERY Lite GRAY is now appearing pink??? Laurie515 you must tell us more. How old is this unit? 4-6 yrs? I suspect that the "Cold-Cathode-Fluorescent-Tubes" that are hanging on the rear of the LCD glass panel and provide white light, have over time, now become tired out. YOU WILL NOT FIX IT!! IT WILL ONLY GET WORSE. Here are some options. 1. Trade in for new if yours is >4yrs old. 2. Check for swapout program with ACER? This is only a dim Maybe thing. You send them yours +$50-$100 and they return a refurbished unit. 3. Find local TV/Monitor Repair shop that knows all about LCD monitor repair. there are also guys on fixya that do LCD refurbishing (new ccf tubes/inverter/smps) Do some web searches on LCD monitor failures and also visit youtube for vid clips of monitor disassembly if you want to see the insides of a typical LCD monitor.
Bye for now. I'm louie12fix on fixya or lmistyrel@ aol.com

TV has color bloches at corners


Assuming this is a tube style TV (not lcd flatscreen) your degausing coil in your TV sounds like it is defective . The Degaussing coil on newer televisions / monitors surrounds the outside edge of the TV and turns on when the TV is fired up. In the old days, their used to be no degaussing coil - when a child would take a magnet to a CRT television, magnetism would remain on the tube and cause discoloration and blotches as you describe (multi-colored blotches) To correct this a technician used to use a degausassing coil and perform a circular pattern on the screen to remove the improper magnetized area. Since the old days, newer tvs have degauss coils built into them, but if they go bad, or always on etc... they can cause the problem you describe.

Red picture


Assuming this is a TV with a picture tube and not plasma or LCD; I'm afraid that your picture tube is dying on you one electron gun at a time. From what you said your green electron gun is almost totally dead and the two remaining blue & green guns aren't far behind. Eventually you'll have no picture at all and I would estimate that to be about 6 more months but whatever the time eventually it will go totally black. These blackout periods will get longer and longer. The only way to fix your problem is a new picture tube but my will probably find it less expensive to just get a brand new TV set.
