Thanks for the info. However, I will say that if you pay big money to purchase a product from a
manufacturer you should have access to all service information pertaining to that product.

Hi Iciallo, As I mentioned, I'm having problems with my tv (I posted it here). In scouring the internet
over the last 10 months, I've seen numerous post where people have referenced documents for toshiba rptv's to that website.
When you go there it ask for a user id and password. Now are all these people (I've noted at least a couple dozen of these) authorized toshiba service people? Must be huh. I have the service manual for my set (57hdx82). However, if this site has service tips, service bulletins and training, I would and should have access to this info. I might read of or discover something that will help me fix my set.They can make their disclaimers for safety and the chance that a person can screw up their set worse if they don't know what they are doing. Fine.So be it.That should be up to me and not them, if I want to risk it. Maybe they do this and make it a big mystery so people will buy new. I don't know. We all know about poor soldering practices, poor design and using inferior parts. They put out service bulletins when these problems are discovered and they get enough complaints about it. A lot of times, this happens just outside of the warrenty period. After this happens, they don't make this info available to the public. This isn't right.
I don't want to take away work from anybody. If I had the money I would of called someone in to get a quote. If it was to high, I would push this set to the curb and get something else. Being you asked, I thought I would get this off my chest. Thanks for replying

Hello again. Thanks for the insight. I did the first repair on the hyper and botched it. I then sent in to the guy on ebay to repair. Make no mistake, I feel this was my fault. I did something to the set that screwed it up worse. At least I know I'm not missing anything on that site now:)

Icaillo, Here is what happened. (kinda long). About 6-7 months ago, when I first turned on my set, the picture would be all wavey with jagged lines. After about 10 mintues, the picture would return to normal. However, I noticed that letters on the screen had a jaggedness about them. This was on standard definition. High definition was fine. So I started combing the net for answers. I came across this thread with a bunch of people with the same problem.

I been following this thread for six months. Most everyone indicated this was a problem with capacitors on the hyperboard. Change some small smd caps on the board. Alot of people done this and reported that this took care of the problem. I decided to attempt the repair. I followed the instructions from a guy who did it on this site:
http://www.dshosu.com/how-to-fix-toshiba-rear-projection-hdtv-wavy-lines/
Before I began, I vacumed out the back of the set. As I didn't want to disturb anymore of the wiring on the board than I had to, I tipped the set over on its face (laid blankets down), removed chicken wire on bottom and unsoldered board from there. Some people have said I shouldn't have tipped set over, but I've read of three people who did it this way and didn't have a problem. Who knows. I bought some caps and opened up the hyperboard.(Its in a metal can). This is where I made my mistake. When I seen how small those caps were I should of stopped right there and sent it out to repair. There is a guy on ebay named ken (search hyperboard) who replaces the caps for $75. Being the dumb I am, I didn't want to wait a couple of weeks without my tv so I prodded on. I ripped up 4 traces unsoldering those smd's. I connected the traces back to where I thought they went with small wires. Wasn't comfortable with the whole repair. I put the board back in the set and tried it. Nothing. I think the first time I powered it up the red light blinked a few times, but everytime after that it would just stay on steady and then go off in about 15 mintues. I then took the hyper out and contacted ken on ebay about fixing my botched repair job. It cost me $180 at this point. He said I had a couple of wires going to the wrong places. He replaced all the caps and I got the board back in under two weeks. He doesn't test the boards in a set after repair, he says he does continuity test on everything or something. Most people I read about swears by this guy. When I got the board back I soldered it back in and tried it. Nothing, same condition as it was before.
This set has two main board, power & signal . hyper is on signal. I took the signal baord out the second time and reinstalled the hyper I got back from ken on my workbench. Should of done this the first time. No blown fuses anywhere. I got high voltage. Nothing comes on the screen. I have a gentleman on another board helping me along with this right now. Its time to break out the scope.
I borrow'd one. Hopefully he can walk me through on how to use it. That is where I stand now.
Hope i explained this right. Thanks for your interest:)
