Picture Tube Failure



There are 3 Picture Tubes in CRT Rear Projection TVs.  Red, Green and Blue. Each tube produces an image that is projected on the screen from the rear. When all three CRTs are working correctly a normal picture is displayed.

SYMPTOMS of a Defective CRT:

  1. One color dominates the picture.  If Red CRT is not producing a normal brightness picture, a Green tint will appear in all images. If Green CRT has a low output, the image will appear with a Red tint.
  2. Poor Focus that appears as a Red, Green or Blue fuzzy glow around images.
  3. Dim Picture caused by weak output from CRTs.
  4. Faint colored lines from side to side when brightness is reduced in customer adjust menu.
  5. After TV is warmed up, one color suddenly dominates

In most cases we expect CRTs to operate normally for 10-15 years.


If your picture was normal before a No Picture condition, most likely CRTs are OK.

Faulty CRT - Incomplete Repair

Tech may determine that a Picture Tube (CRT) or other part required for repair is too expensive and repair is too costly.

1. $35 S/call (In Service Area)
2. $30-$60 Minor repair or troubleshoot/Identify part required
3. $65 - $95 total -  Incomplete repair

On-site Troubleshooting is available in Vancouver, Edmonton, Toronto and London service areas.

If a CRT is faulty, the cost of parts and expected future service for adjustment is too expensive for repair.

If a  CRT or Picture Tube is defective, the cost of repair  is unreasonable. Reliability of the repair becomes an issue. CRT replacement usually requires further visits for alignment as the new tube burns in.  The other tubes may be unreliable if one is defective.

If your picture was normal before a No Picture condition, most likely CRTs are OK.
