Question about Mitsubishi WT-42315 42" TV

WT-42413 continues to shut down. Need to wait 15 minutes to restart

This appears to be a common problem with this Mitusbishi TV. I had a 2003 WT-42413. It would run anywhere from 20 minutes to two days and then quit. If this is happening to you, do the following. Press the menu and input keys on the front of the TV at the same time. The green light on the front panel will flash. Notice the two digit number that is flashing. It flashes a series of times, pauses, flashes for the second number and repeats for about 30 seconds. My code was 2,3. This is a problem with the CRT deflection. Basically, the TV is registaring there is too much current, so the protection circuit is shutting it down. After 15 to 20 minutes the TV resets and can run again. Most repair people I found replace at the board level, not component. This repair is very costly. Alot of it is in the labor, because the repair man has to redo the convegence setup per factory. There are special codes they enter in your remote to do the factory convergence. The user convergence is just minor adjustments. My repair man spent over two hours doing this for both the 'regular' mode and the HDTV mode. Two separate convergences that should be set up if you use HDTV. He asked me if I wanted to skip it to save money. After this was all said and done, the repair bill was $750. I held off paying until I made sure it worked. It did not. I then swapped them for a 2004 WT-42315 they had on a trade in with the same problem. However, the board fix above did correct this one. So, my Stereo Store was gracious and did the swap at a discounted price of $500 (yes, less than the repair that did not work). This TV is working great. Of course, many are saying for that money, just get a new LCD, but I was a fool who had a cabinet built to fit it perfectly. With my home being only three years old, did not want to hack on the cabinet yet. Bottom line, if you have this problem, and your TV is out of warranty, it may be best to buy a new LCD or find a repair man that can replace on the component level. Don

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.

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.

Standby light is flashing 10 tims Model KV-HR36

Try unpluging your T.V. for 5hours+, then turn it back on. Worked for It's called a "hard reset" by sony.

Do the following steps
  1. Check the Sony remote for a button labeled "Sleep." This allows you to cycle through the sleep settings and determine how long you want the TV to remain on.
  2. Step 2 Press the "Sleep" button. You'll see a number come up onscreen: usually 15 or 90. When you press it again the number changes, moving up and down in increments of 15. This is the number of minutes the TV will remain on before it goes to sleep. As you cycle through it, you should see a setting with the words "Sleep Off" appear onscreen. If you leave it there, the sleep setting should cancel, allowing you to turn the set off when you like. If you miss it, just keep pushing the "Sleep" button. It will continue to cycle through the options until "Sleep Off" appears once again.
  3. Step 3 Access the timer function to shut off the timer by pressing the "Menu" button, then cycling through the onscreen options until you reach the "Applications" setting. Press it, and then cycle through to the "Clock/Timers" option.
  4. Step 4 Highlight the "Timer 1" setting and press the "+" button. If it's showing a given time, you'll need to deactivate it. Use the up and down arrows and move through the possible options until you come to the "Off" setting. Leave it there; that should shut the timer off.
  5. Step 5 Repeat the process with the "Timer 2" setting, a little further down the "Clock/Timers" menu. Set it to the "Off" position just as you did with the "Timer 1" setting.
  6. Step 6 Press the "Menu" button when you are done to exit the menu and return to the screen. You should be able to view the Sony TV as normal with no danger of it turning off.

good luck

TV shuts off after 15/20 mins!!

 Dear customer,
       It could be the transformer. The problem with protection circuit shut downs is you don't know which section is causing the trouble.  The protection system is really just a current sampler that when it detects an excessive current it opens up the power relay and shuts the power off.  And, as you indicated, unplugging for a few minutes will reset the protection detector.

But, there are about 8 or 10 sections within the tv and you don't know which section has the excessive current.   Most common causes are power supply, high voltage supply, deflection amplifiers or audio amplifier.  It usually takes a tech a few minutes to take some voltages and other checks to zero in on the culprit. Once the section is known then that tech can troubleshoot it for the bad component or shorted condition.
               Usually  it works fine until there is a signal coming in through the coaxial port. that is wen the tv gets switched off. Its a possibilty. Checking the  power supply unit of ur tv and see if it has malfunctioned and  check your power cable for starters.. 
Plz rate this solution.. thank you..

Sony 36brx800 shuts off on own

As a TV tech the simple answer is no! If you were a well qualified electronics tech but just not used to TV's then the answer might be a very weak 'maybe' and that's if you had a TV tech talking you thru the whole process on the phone.

shutdown probs can be the power supply, bad solder joints, or also very likely the high voltage power supply. Meaning the area where the TV generates upwards of 30 thousand volts!! The set has overvoltage protection that makes sure that things don't completely fry, catch on fire etc.

Ya really need special training to avoid getting zapped with tazer like volts or worse! Sorry but safety says better stay out of this one!
