Question about Toshiba 61H70 61" Rear Projection Television

1 Answer

Convergence when hooked to HDTV

The convergence on my Toshiba 61h70 works great. However, when I hooked up a HDTV Cable box using component cables, the convergence becomes totally off. The red and blue wont line up while using the component cables and they become slightly bowed in the middle, but are still lined up when I switch back to a coaxial connection.

    How do I realign each one? I can use the remote to realign it in regular mode, but the red will not line up when its in the HD mode with the remote.
    Is the realignment something I can do? Or does a technician need to do it?

Your set needs to be realigned in each format, then settings saved

    you can do it yourself, you would definately need the service manual as its a detailed process done in the service mode. If you would like a link to purchase a service manual let me know as I can post a link where they will email it to you after purchase.

Convergence off on Digital Cable


convergence for the rca itc222 is set individually for digital and analog tuner. Most of time the set will have to be converge in service mode. as a tech i would not recommend getting intoservice mode. but the key is the the convergence has to be set indiviadually for each tuner. You could try autoconverging in digital or even manualy converging

Toshiba 61H70 Weird Convergence Issue?


They may have gotten some cheap convergence ICs, thats a real possibility. I would recommend switching the two origional STK392-110 with some STK392-150 they will run alot cooler and last alot longer. Just use a good coating of heat sink compound on the back of the ICs. I will post a link where you can get top quality Convergence ICs and they provide free instalation instructions with pictures so you can do the job yourself in under an hour and save quite a bit of money. Heres the link.

Toshiba 61h70 Picture Problems Hello, I have a Toshiba 61h70 TheaterView HD Projection TV, and was recently having some slight convergence issues (red was out of alignment and could not be adjusted). So I researched and found that the IC?s (STK392-110) needed to be replaced. I initially purchased them on eBay, to later find out that they were cheap clones and did not work (they made the convergence worse, actually). I then purchased 100% Sanyo IC?s from a reputable dealer and replaced the IC?s again. Once finished, I then entered the service menu and adjusted the convergence alignment. Once the alignment was perfect, I hooked back up the TV antenna, the DVD player (composite), and the S-video from my computer. The convergence is fine, but now I?m having a totally different issue ? the video is ?scrolling?. The menus will show up fine, however any incoming video inputs will show up okay for a split-second, but will then flash and the picture starts to scroll in different directions. This happens with any of the video inputs. I checked and changed all the service menu items to factory defaults, however this had no effect. I have pasted a link below to a short video that illustrates the issue that I?m having. Please note that the video starts off with a black screen, showing the ?input? menu, and then I selected the ?TV input? and changed the channels. You will see the picture fine for a moment when the channel is first changed, but then the picture will start to scroll. Any ideas of what would be causing this? And how can I correct the issue? I?m not a TV repair expert, so I?m not even sure where to start. Any help would be greatly appreciated. http://s75.photobucket.com/albums/i303/hybrydmike/?action=view₪t=TV_Troubles.flv
