Wavy line on a DLP SAMSUNG 65 INCH PROJECTION TV


Bulb does not do anything but project white light. Wavy lines are a digital board problem. You should have a tech look at it.

Double vision on the left edge slightly


Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as 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. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.

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.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

You probably have a V26 chassis. The only fix to this problem now that parts are no longer available from MITS is to call their Consumer relations dept. at 800-332-2119. If you have a qualified tech come out and estimate the job, Mits will offer you an attractive discount on a new model. To repair your problem would be around $750

LOW SOUND OUTPUT ON MY REEL TO REEL, SOMETIMES ON ONE SPEAKER ONLY..


Let me guess - the LEFT channel.

If it's a 4-head deck, the Forward tracks are arranged across the physical tape surface, front-to-back as follows:

BACK
===========
Side 2 Left
Side 1 Right
Side 2 Right
Side 1 Left
===========
FRONT

As you can see, the Left channel is close to the edge of the tape where most tape and head wear occur. High frequencies are affected first.

If you examine the edge of the tape when it is stationary there should be no waviness as this would cause poor head-to-tape contact.

Shine a high-intensity light on the tape where is passes over the heads. You should be able to identify the tracks. Looking closely you might also notice a worn pathway across the heads caused by miles of tape over the years. It changes the contour of the heads and how the tape rides on them. Wear can look like shiny bars (perpendicular to the tape travel) with rounded or wavy edges (not ruler straight).

Or it could just be dirty heads and transport.

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Westinghouse LCM-22W2 has "ghosting"


Usually, LCD monitor ghosting appears when the cable isn't tight, the cable is faulty, or low quality. The cable should be less than 8-10 feet long. Try using a different monitor cable (they're mostly interchangable) and see if the problem goes away. I'd put my money on the cable or a loose cable connection.
