My Element 32 inch tv has black screened.


hope I dont sound too crude, but have you checked the contrast and brightness controlls ?? they may be labled as 'picture options' or some other odd label...

does this tv have a LED, LCD or the older CTR display ?? If it is LED or LCD, then the light source that illuminates the screen are not working.. this light source could be damaged..

Double images purple and green. try to convergence lines are lined up but there is a wiggly green vertical that won't move.


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both. Repair kits with instructions are also avail from www.TvRepairKits.com

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

TIME STAND BY IS ON BUT TV WILL NOT POWER ON


There may bad news on the repair from for this particular TV. Having worked on several large screen projection TVs, the prognoses is bleak.

This particular model uses 3 high output picture tubes (R,G,B) and each are triggered (shine) from the exact same "fly-back transformer". All the older picture tube style TVs have used this device as the sole means of generating the actual light that projects to your eye. When it goes bad, the whole TV shuts down and refuses to operate Since the early 80's anyway).

Can you get another fly-back...? Maybe, but not without an astronomical price tag attached to it. That's not even including having it installed (this ****** just plain isn't plug and play).

Then once all that is done there is this wonderfully expensive process of re-alligning your picture. See, once the new transformer has been put in the guns (R,G,B) have been 'pulsed' into different projection points. So your tehnician gets to stand on his head and nudge-fudge and cuss the picture back to a presentable state.

If there is a huge sentimental attachment to the TV then it might warrant the expense, but if I read this model correctly, you'll have to have a digital converter box or cable to get the proper picture anyway. Sadly, it may be time to look into another veiwing investment.

Hope this helped...

Tv comes on has good picture and then just shuts off


In these cases you might be able to see a picture by shining a bright light right next to the screen front. Do not put the light there for very long or you will end up with a permanent bright spot burt onto the screen. I have discovered that applying light pressure with a 3/8" thick rubber or plastic shim corrects a panel inverter/driver board/card solder problem with many flat panel TVs. (Removing the back is required, try light pressure against the board while wearing rubber gloves and tv is then powered on.)

I have a 50inch DLP Hitachi that is 3 and a half years old. I replaced the bulb about 5 months ago now the blacks are blueish and it has a greenish blotch on the screen. It also leaves an image on the...


Contrary to popular belief, any display product can have "Image Retention" and even "Burn-In". This is true for Plasma, LCD, LCOS, DLP, and CRT. I do not see a model number provided, but I would bet that you have an LCD rear projection TV rather than a DLP projection TV. If this is the case, the Blueish and Greenish blotches you are seeing on the screen are the result of UV light damage. UV light will move heavily damage the Blue panel, due it's short wave length. So, bad Blue or Green (absence or Blue) is typically the the first visual indicator of a problem. Replacing the Light Engine will resolve the problem.

Take a strong flashlight when the set is on and shine the light into the screen see is you have a picture as it may be the backlight. If the screen lights with no picture its a pcb board problem. Please verify your model number and I will try and assist you.

I have discovered that applying light pressure on the video card with a plastic shim corrects a card solder problem with these TVs. (Removing the back is required) In these cases you should be able to see a picture by shining a bright light right next to the screen front. This goes for many screen shutoff problems on flat panel monitors and laptops. Do not put the light there for very long or you will end up with a permanent bright spot burt onto the screen.
