20 Most Recent Toshiba 53HX71 53" Rear Projection HDTV-Ready Television Questions & Answers

I would expect that the bulb has failed. Toshiba DLP Replacement Lamp Toshiba DLP Bulb Part 1 If you decide to replace bulb I suggest that you replace with the best quality bulb. I found the brightness between good and best bulb was significant. I have ordered from the internet and have had great results. There are other possible causes of lost video. The bulb is only the most likely. Good Luck

I have a 53hx71 that is haveing an issue with my blue on covergence. I have replaced both the chips and it still wont move up or down when i try to adjust manually and the auto adjust wont work either can anyone help?

A few questions for you that might narrow down the issue.Where is DVD connected at?Have you tried it on all rear inputs?Where is Direct Tv connected to at the set and does it work normally?If input it (the player) works with something else connected (rules out the input used) then I would suspect some setting in the players (identical model brand?) is set wrong.

A regular mirror will not work as the mirror has special construction; What you can do and our shop has done this is find a used one bigger and have it cut down to size.If it is Toshiba you can also call ANDREWS ELECTRONICS in LA (they have 800 number) and see if original mirror is available from Toshiba. There are also some sites on the internet and if you google the model number with the word mirror you will find themBe extra careful if mirror was broken as pieces will be very sharp.Entire front screen unit will have to be removed to get at it and or replace it.Let me know if you have questions.SD TECH

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. 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.

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.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

Yes,the covergence ICs and precision resistors can be replaced to rebuild the area. A reputable shop may charge around $300 . If you are technical person,I can guide you further to do yourself!

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. 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.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms

• Screen Looks 3-D
• Colors wont align
• Screen may look distorted or warped
• No Audio/Video - makes a chirping sound.

Problem #2

I will tell you what I think it is.Note,high voltage,capacitors stay charged when tv is unplugged.Just don`t touch those ugly big things in there,lol.Now these circuit boards will unsnap,and come out,to a point.Some wires may need to be unplugged.They will only plug up in one spot,when you go back with them.Oh,and trust me,do not use a vacuum to clean it out,the dust,and debris is magnetical,it will ruin the vacuum,and electricute you.Blow it out(using face mask)with air pressure.Use googles too.Now when you pull these circuit boards out,look under them.You are looking for a burned spot.Look where the solder joints are,holding a heat sink,from the other side.This is a block looking thing,about 2 1/2 by 2 1/2,by 3/4 in thick.Has fins on it.This has a chip on it,that is on the heat sink.The burned out spot is a cold solder joint,this means bad solder job,from factory.Clean it with electric contact cleaner,that you can get at N A P A auto parts,or radio shack.Then re -solder the leg of the heat sink to the circuit on the board.The leg,looks like a piece of small wire,One stran of stiff wire.This solder was not holding contact,and melted away in time,causing it to short on,and off,killing the tv,and trying to work.Pull each circuit board and inspect under each one.I hope you find this problem,and it fixes the problem.If you need to ask anymore questions,please ask,thank you,if this was helpful,please let us know.

I presume the actual model number is 53hx71, most of these sets use two of the STK-392-110 CONVERGENCE IC chips.

If Blue is skewed (or red) and will not move in some direction one of the two chips and or one or more of the 1.8 ohm protect resistors around them are bad. Both chips and any bad resistors need to be replaced and the set adjusted. Considering you can buy a pair of the chips on Ebay for less than 14 dollars plus shipping, if you or someone you know can do this you can save the set and a lot of money.

Including other things you will need the total parts cost should be under 30 dollars total. Two things are involved in this repair: Gaining access to the chips and unsoldering them and replacing them. The chips are on two large metal heat sinks with fins and usually are in the middle of the set side by side. they are black in color with 18 pins each and about 2 1/2 wide by 1 1/2 tall and will have the full STK number printed on the front of them in white letters.

Most shops are going to get 300 or more for this kind of repair and it should be able to be done right in your home--takes about 1 hour--I have done hundreds of them here. If you or someone you know can do it I can give you general instructions and tell you what you will need and where to get the chips on Ebay. I have helped several people here do this and almost all of them were able to do it.

I will if you attempt it be here if you have problems or need further help.

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.

I would recheck the wires that got switched first and make sure they are right!

it sounds like the vertical output IC went bad which could be a bad connection or a bad capacitor \. Do not attempt to fix this yourself have a technician do it unless you have experience soldering it shouldn't take very long and it shouldn't cost very much either.

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.

your having convergence circuit problems, you`ll need to change the convergence IC`s and any burnt resistors in the convergence circuit, if you have questions e-mail me back, good luck, BMW Rider
