Question about Toshiba 42H81 42" Rear Projection Television

2 Answers

Where can I getr a hyper board or fix the hyper card?

Hi,

My set has the horizontal jags! Everything syncs except for the video. The only way I can describe it is the frame buffer has sahiftess that creates multiple horizontal saw tooth waves that run vertical down the screen. It does it in all modes. Replaced the caps already.

    JSavage Here! Well, my Hyper-board was shot. I sent it to PTS to have it repaired and they rejected it for cracked runs. I was able to find another TV with the board and I bought it for $75. It fixed that problem. At least I can whatch HD stuff!!



    My sugestion is, by a new TV, but wait for the prices to drop some more. I have seen 42" LCD TV's drop more than $700 since December 2007. The 42H81 is an OK TV when it works, but the new technology of 2007-08 is much better. HDMI is the way. Most component players will not play at the correct frequencies for the 42H81. That really sucks!



    However, There are devices that will put out 480i, 720 i, or 1080i. anything else will not work on this set.



    In my oppinion, the set is not worth fixing unless it cost you less than $200 as it did me.

Another guy with the same problem, replaced the Hyper Module capacitors (not the whole module) and the convergence amplifiers.

Vizio E470i_A0 shutting off after loosing horizontal frame sync


It could be several things but I'd start with a main board, the fact its shutting off kind of drives me away from Tcon as that shouldn't shut the set down if there was an issue there, it also could be power supply, you could test the voltages from the board once it starts giving issues and if some are off then change the power board.

Toshiba/ 42H81 / hyper board


You can either yrplace your Hyper board, or replace all the serfice mount capacitors in it. The cap replacement fixes this 90% of the time.

Yeah to sync the controller all you do is find the little button on the back on the controller on the left handle thing and hold it and the sync on the xbox. I had trouble at first two. But its a great controller.

I still get error message with Hyper R4i


Go to http://www.hyper4i.com/

Download there the wright kernel and the newest firmware for your hyper R4i.

Delete on the memory card, downlisted folders and files.

Folders:
_system_
moonshl2
SSTATE
Files:
_DS_MENU.dat
_DS_MSHL.nds
HOW TO USE.txt

Put the new kernel files from the archive to the memory card and from the other archive de nds rom that contains the new firmware.
Boot using the new kernel and run first the new firmware rom, turn off the ds when it tells you to do so, this makes the Hyper R4i working on DSi's with firmware version v1.4.

Delete the firmware rom from your memory card because you won't need it anymore.

The Hyper R4i should now work as it should.

Note that the SAVE folder contains your safed games, if there are still problems, try to delete this folder to.

Succes.

Removing the hyper board


I ordered a Next HYPER Board, PD0264A (as seen in the service manual). I ordered it from Vance Baldwin Electronics (vancebladwin.com) The only part available is a substitute, PN 23148017 MODULE, SCAN CONVERTER. The cost was 219.50. It was backordered so it did not arrive for almost 3 months. Install is a little tricky. It is accessed from the back. You need to remove the input board, the video processor, and some brackets to get to the Hyper board. The hard part is putting the TV on either its front or back (much eaiser if its laying on the screen, although more dangerous) and then desoldering for tabs that go through the signal board. There is a lot of solder on these and two of them have been twisted for some pain in the **** reason. They are difficult to twist back without damaging anything. When it is desoldered and twisted back, the board should come out. Be careful not to crack the signal board when pulling this out as I did. See above for what it does. I found a slight chip in my signal board and it took some difficult board repair to get the runs connected again (please be careful, as the repair is difficult and not nearly as relaible as an unbroken board.

Anyways, install your new board, put everything back, and power it on. I'm sure you'll have to do a convergance and some other adjustments, but if your doing this fix, a convergence should be cake. My problem has been fixed and I'm thrilled to not have to trash my TV.

I would think that the signal board would be more suspect than the hyper board for the symptoms you're describing. However I would recommend getting the service manual and doing some troubleshooting rather than just replacing circuit boards.

Hyper module


no it does not need to be reseated. Most likely there are bad capacitors inside of it. The Hyper, or whats really a scan converter, is located right behind the input board. It is a square silver box. Good Luck

Horizontal sync


zeutaluras, My guess would be the same as yours because the horizontal osc. is synchronized when you apply the signal to the HD inputs. I am assuming the signal with embedded horizontal sync and composite video passes through the tuner boards as you mentioned. I'll confirm with the schematic once I see it. If it is a separate board can you get one to substitute? I think you may be able to locate the problem with an oscilloscope and schematic if you can access different points in the schematic. I'll try to help once I know more. My problem prevents any type of built in diagnostics since the set doesn't power up.
