20 Most Recent Toshiba 46H83 46" Rear Projection HDTV-Ready Television Questions & Answers

"This TV is not intended for connection to and should not be used with a PC (personal computer)". This statement should say it all.

How are you connected and in what way? You should be able to rule the set in or out:

First: does the set have sound with only a DVD player connected to a rear input?

Second: are the speakers turned to OFF in the main menu?

give as much information as you can so I may be able to help.

I think the screen adj is too high on one of the screens.
How and where did you touch focus?


Toshiba 46H83... | Answered on Aug 15, 2014

You may have one of two issues here--noisy lines when set first comes on left to right---they clear up after 10-15 minutes.

Other possible is a convergence problem--colored lines, 3 d looking etc--see typical photos attached---Problem does not sound like a cleaning issue--

let me know which issue you seem to have with a comment here.

Still looking for this tube?

I suggest you replace the signal connecting lead as it sounds like there is a poor connection there somewhere.
I have had that on DVD players.
Hope this helps.

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 photos of convergence problems.



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

you more than likely have a bad panel inside of your tv. you can have someone repair it but it's not recommended as it's pretty expensive. You should just invest in a new tv.

Sounds like blown invertor board that powers the backlights (if it is LCD or PLASMA). If your lucky and its just the invertor board blown it could cost anywhere between £50-£150 for new board (without labour).. if you are UN-Lucky, then the backlights themselfs may have blown which is *usually* an un-economic repair.

shutdown pc completely. unplug hdmi cable. turn tv on. plug cable back into pc and power up. pc should recognize the tv.

If you can't adjust the red convergence in one direction then it is probably one of the convergence IC's. If you are handy and can solder then read on.

Before you replace the IC's, check for bad solder connections at the IC's and output resistors below the heatsink. Sometimes the solder connections crack over time.
Make sure the tv is unplugged for at least 5 minutes before poking around. The power cord can be unplugged from the power board and removed to keep anyone from plugging it in while you are working on it.
The STK's are the large 18 pin integrated circuits (chips) mounted to the large heat sink on the convergence board. This is the board on the right when viewed from the back of the TV.
The resistors are beneath the heat sink on the left side of the board. There are also fusible resistors, like #7711, on that side. There are NO pico fuses in this area.
Check the fuses on the Power board. This is the board on the left when viewed from the back of the TV. You can remove both boards in the carrier by carefully unplugging all connectors, noting their locations and routing.
To remove the high voltage wires from the splitter, mark them for position then grasp the boot and turn counter-clockwise about 10 degrees to unlock them and then pull up while holding the High voltage splitter. The small high voltage wire can be removed from the flyback transformer by pulling hard while holding the flyback.
STK392-110 can be replaced with STK392-120, STK392-180, STK394-160.
I have found most of the parts at newark.com. Also check out this site for some very good info: http://www.hometheatershack.com/forums/diy-repair-maintenance/5600-crt-based-rptv-convergence-repairs.html
btw: I am not affiliated in any way.
Make sure that while you have the boards out you look for any bad solder connections. A lot of problems arise or return because of this.
I hope this helps, I have been doing a lot of searching to get this info and hope it helps you. Too many people want to trickle the info and pretend they are giving you gold. A few hobbyists or people that can't afford to pay $300+ for repairs are not going to hurt their business.
Be safe and share knowlege freely!

its the fault in the power supply board . initially unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the circuit board are getting short tracked within few minutes of working. in this case the circuit board needs to be checked with a multimeter.the faulty and burned out component part should be detected and then should be replaced with the help of soldering iron.to make it proper. to avoid further damage i suggest you that do not on the tv again and again as it will short some more tiny components and the reparing cost will increase as per that.at present its the normal circuit short problem in the tv get it repaired before using the tv again.
also you can get new replacement power supply board.this clears the problem completely.
you can get the required board and components at ----- www.partstore.com -------- or from ------ www.radioshack.com ----
if you are not familiar with doing this you can get it done by local tv repair technician familiar with this model tv.
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

Could be either an amplifier failure or a short in the speaker connection. For the latter, try removing and cleaning the speaker connections at both the unit and at the speakers. Then reconnect the wire, being sure to return the leads to their former location such that you don't accidentally reverse the leads.
