Removing the hyper board

Got everything off but the hyper board itself. I am not sure how to get this part off. Can someone explain this process. I have a Toshiba 57H82. And are the caps inside the hyper board? Thanks

I ordered a Next HYPER Board, PD0264A (as seen in the service manual). I ordered it from Vance Baldwin Electronics ( 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.

Picture flutters vertically

Many of these sets (57H84 etc) had a problem with the "Hyper" board.

It is a circuit in the set that processes all signal from the tuners, and all inputs.

Most of the time this problem shows up when the set is first turned on and after several minutes the picture goes to normal----the delay if you have this problem slowly gets longer and longer.

The hyper board is NO LONGER AVAILABLE-and the only way to correct it is remove it and send it out for rebuild.

There are about a dozen very small "surface mounted filter caps" on the board that dry out and cause the problem.

2 people with this problem were able to remove the board and replace all the tiny caps but IT IS NOT EASY AND NOT A TASK for a do it yourself person unless you have some real skill.

The problem usually looks like noise lines from left to right across the whole or part of the screen---if it started gradually---it is a bad Hyper board.

Let me know by responding with a comment if you need help or advise.

Picture tearing in first two minutes after power on.Toshiba 65 H81 rear projection.

65H81 along with several other models has a problem--I have the Toshiba Service bulletin that explains this.

Basically the set you have and others like it use what is called a HYPER board (circuit board) that processes all signal for the set from all inputs---the way the problem usually begins is lines/noise for the first few minutes and then it clears up---as time goes by the length of time to clear up becomes longer--at some point it will not clear up at all.

The Hyper board is Soldered in in most of these sets and not a do it yourself repair---yes--I had one other person who was on this site with the same set and problem and with directions and the photo of the board from the bulletin he was able to repair the board himself.

What is happening here is this board uses several surface mounted filter caps that begin to dry out and fail---caps that have lost value tend to try to function better after they get hot--hence the delay until the problem goes away.

This board is NO LONGER AVAILABLE FROM TOSHIBA--only two choices if you want it fixed--send it out to a company called PTS ELECTRONICS and they will repair it for you--last time I checked cost for them with shipping was over 200 dollars plus someone has to be able to get the board out safely and install it back after it is repaired.

Second choice is to find someone who can replace the 10 caps indicated in the bulletin (there is a photo showing which) which should cost under 25 dollars parts wise--Understand--most sets use filter caps that have two leads---the leads go through the circuit board and are soldered to the bottom of the board--these sets use tiny caps with little tabs soldered to the TOP of the board--you have to be very careful removing them not to damage the board.

If you want I will try to post the bulletin for you to look at--it is acrobat reader and may or may not post well.

The screen is shaking horizontally. It does this when I first turn it on and gradually gets better after about 30 minutes. There are also 2 or 3 vertical lines going side to side while the picture is...

42H83 is a Toshiba first made in 2003.

What is wrong (98% chance) is the HYPER BOARD in this set is now failing----all signal from all inputs is processed thru this board.

Considering the board is now only available on a rebuild basis----and the cost for this is well over 200 dollars not counting labor to remove--replace--set, unless you know someone who is VERY GOOD AT SOLDERING-----not worth repairing.

What happens here is this board has close to 20 surface mounted filter caps---with time and heat they dry out---usually the time before the problem clears up will get longer and longer---leaking caps may start to function to some degree after they get hot--hence the time from dead cold until the set works.

Most caps have 2 leads and are soldered through the circuit board----these are very small caps with tabs on them----and are soldered to the top of the board.

I am sorry to give you not so good news--but based on your description---I am sure it is your problem.

Call around your area telling them model number and you suspect it is a bad HYPER board---if a shop can actually fix it(replace the caps) parts cost would be under 30 dollars---

Any authorized Toshiba repair shop can go online and see the service bulletin for this--they have a large color picture of the board and indicate which caps have to be replaced.

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.

Toshiba 57h81 location of hyper board and remove procedure

Hyper board is located directly behind the input board, this is where all the tv conections are, then they are two tabs soldered from the bottom of the board then it simply unplugs, But replacing all those capacitors on that board can be a little tricky, replace all 10up @16volt caps and that usaly repairs the board

Toshiba 65 inch projection TV

Yep, sure sounds like a tuner pproblem my friend. good diagnosis! If you have any soldering experience and know how to work on solid state circuit boards, then you should have no problem replaceing the tuner for this set. Now it could also be a problem with the HYPER PCB assy. This is what controls the tuner and some sets the tuners on the hyper board. the complete HYPER board is avail. at for about 165.00 + shipping. You can also check with for a rebuilt hyper board assy. If you have no experience with TV repair PLEASE stay safe and call in a trained servicer to assist you with this problem. Good Luck
