Re: problem with y toshiba 53hx71

There is a fairly common problem with those symptoms. Try removing the srs-wow board, stand-up audio board next to the tuner. If the picture clears up it's likely QD01 on the srs-wow board loading down the scl & sda lines. QD01 is an Njm1136d Toshiba p/n# 23009142.

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

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.

My Toshiba 53HX71 takes about 20 minutes to "warm"

This is a symptom of poor solder connections inside the set. The set will continue to deteriorate until it won't turn on at all. This is essentially a labor only repair and should not be to expensive for any TV service shop. Once this has been repaired, the set should work for many years to come.

These poor connections are caused by the continual heat/cool cycles because of use and is normal.

Most of the time the Hyper Board failing is the cause of this problem. It will eventually get worse where it also affects the HD ins. Unfortunately the Hyper Boards are no longer available from Toshiba and have not been available for quite some time. My suggestion is to coast with it and replace the Set when the HD ins fail.

How do I remove the screen of a Toshiba 53HX71. I

You do not remove the screen on that TV. Doing so will mess up your convergence.
Chassis must be removed by a professional.

Call the manufacturer to find you nearest authorized service center.

53hx71 toshiba

I had this problem and paid a repairman to fix it. He said he has seen it often in this model, and immediately repaired it. It works now. He replaced two 18 pin switching modules, about a 1/4" x 2" x 1"; and 3 "micro-caps"(fuses?). It took about 45 minutes and cost over $400.

Do the wheels easily come off this unit?

They should just be standard casters on the bottom. The tough part is laying the TV on its side to remove them.
