We have a 57H82 Toshiba set about 4.5 years old. Asking if it easy to take the metal box apart and does the new HYPERBOARD pop in. Easy to replace those 16v/10uf caps or best to buy the board. If so how much would the board cost?.
Dougers, I am next door, in Alberta. I have fixed my hyperboard by
replacing the surface mount caps myself in my workshop for a fraction
of the cost of a replacement board. See my other thread for more information.

Re: Wavvy lines, wiggy
The hyper board part #23148024 is NLA. There are 2 solder tabs on each side of the board that have to be usoldered from the signal board and then the hyper board will unplug. I do not recommend changing the capacitors as they are surface mount and it is very easy to damage the board beyond repair. PTS electronics will repair the board for you but will not do so if the board has already been damaged. I have one in stock.

this is known as hyperboard or hypermodule problem. Now toshiba knows about this problem (common) and has issued repair instructions for service centers. The bad news is this repair is quite labor intesive. When this fault first occured the thing to do was to replace the cuircit board. as time went by the board became more difficult to find. So the discovered and intructed how to fix this board on the component level. The repair involves removeing the board. This board involves removing alot to get to it. Then replaceing 11 micro capacitors. Let me just say it takes very experience tech some time and a large magnifer with twezers a few hours to do this. i have repaired a few and i still have trouble. it is very easy to damage the board. IT CAN BE FIXED and labor cost might add up. our shop repaired about 2 of these of month for around 300 and most of that was labor if you choose not to fix it it might last 6 months or a year.
Is a common problem. Your hyperboard has failed. You can get a repair kit from www.TvRepairKits.com or buy a used hyperboard - but it will also fail someday unless it has been repaired with better parts than what the factory supplied.
Sounds like a bad tuner/decoder on the Qam analog side of things. You can bypass this with a Clear qam converter box or a analog to digital tuner box or simply having this repaired upwards of $200 bucks.
You can try setting the convergence for your tv which will be explained in the manual (if you don't have it anymore you could try the support page for Toshiba). I had a model like this, and when they get old you can get alot of dust inside which can affect the tv, and just years of use can sort of wear them out. I am a certified installer, and to get mine back to an old tv with a good picture was going to cost me $250 for the parts necessary. An electronic repair bill could be in the hundreds of dollars and you would still have an older tv. If you don't mind the slight inconvenience of waiting for it to warm up or the lines, that option doesn't cost any more money right now.
It's sent via Pando and you should get a link to it in your mail. To open it you'll need Pando, it's a free download if you don't already have it... The hyper module on that has about 10 caps that are common in that failure. If you need anything off board don't hesitate to ask.

Service manual won't help much in the hyper board and that's likely the problem.. Simply remove the hyper board and open the can. Inside you'll see a number of smd caps. There are 11 10mf/16v that need to be replaced...
Heres your link for the capacitors
Loads of info here about the board
This is a somewhat common problem having to do with the hyper module, Toshiba p/n#23148024
There are a gouping of 16v/10uf caps in the hyper board that fail causing the distoritions you're describing here. At first, as the module begins to go bad the distoritions are present and usuallly go away or fade significantly as the set warms up - - this gets worse until the distoritions don't go away at all... From what you're saying you're at stage three already. :)
You have a few of options: (1) local repair shop pull the board and replace the caps or module; (2) Pull the module yourself and repair or send it in for board level repair; or (3) pull the hyper baord, order a new one and put it in yourself.
For 2 or 3 you'll be better off having the service manual and if you need it just email me privately and I'll send it. Make sure in your request to tell me the model number and reference something of this repair so I have a clue of what you need.
BTW the hyper board is on the left side of the unit mounted vertical on the signal board inside a metal can.
