Question about Projection Televisions

2 Answers

Convergence problems Several weeks ago we moved our tv when remodeling and also when we were scraping up the old flooring which made a lot of vibrations and noise our tv's convergence was messed up. We tried to fix it by using the convergence 1 and 2 but the red is shifted to left and cannot be adjusted. The green seems to be aligned on convergence 1 and the blue is fine. Please help.

Re: convergence problems

Hi 4isenuf.
You have a problem with the convergence ICs.
It your Tv dosent fix by useing the convergence or autoadjustment, that means you have to replace your convergence.
If you want to know more about what to change and you are wiling to open it up, let me know i can help, you, but if you dont have experience in doing that, i strongly recomend you not to open it, but call an expert.
They may charge you something relavively expensive (above 200 maybe) but its better to pay them that than risking your TV and breaking it furthermore.

Re: convergence problems

The problem is in the convergence integrated circuits.(chips) There are two of them that need to be replaced and I recommend to consult a local tv repairman. Because the old ones must be unsoldered and the new ones soldered back in with a soldering iron of good quality. Requires proper tools to unsolder

Tv has double image color red and a curl line on left upper corner also sometime in middle of tv it has line

This sounds like a problem with "convergence" of the TV. Convergence is the electronic aiming of the Red, Blue & Green projectors. Typical convergence problems look like double or triple images on part or all of the screen, wavy lines, curled edges, excessive red, green or blue color or tint, etc. Sometimes, convergence issues can be corrected in a menu setting of the TV that has to do with "Picture Settings" or "Advanced Settings".

If the colors are out of alignment a great deal or went out "all of a sudden" it will probably not be repairable via the menu adjustment described above - but is certainly worth trying.

If it does not straighten out with the menu adjustment, it will probably require replacement of the convergence integrated circuit(s) chips located in the TV. This was a big ticket repair years ago, but can be done sometimes for as little as $40 in parts. Don't let the low price fool you though.. It can easily take several hours (or more!) to access, remove & replace the components and reassemble the TV. Soldering skills are a must - and I'm not talking about soldering plumbing pipes here either. These are delicate electronic parts and need a 15 - 30 watt soldering iron and desoldering braid or solder ****** and LOTS of patience to perform CORRECTLY. As such, it is another "not a DIY project" unless you're willing to turn your TV into a large floor model paper weight. If you decide to attempt this repair, you should google your TV brand and model along with the term "convergence". Parts, costs and procedures vary by TV. Unplug the TV for a day or so before starting the work to let capacitors discharge fully - just to be safe. Lastly - don't forget the heat sink compound - it is an absolute *must*!

Toshiba 53h71 Blue Shadow/Shade problem

If the shadow is off to one side then it's a convergence adjustment. If it is a blue outline it may be your blue focus. There should be focus knobs behind the speaker cover. They are usually covered by a piece of black tape. The convergence screen should have a prompt for changing the color you are controlling, possibly exit button. Toshiba has several of the older owner manuals on their site as archived models.

Problem after replacing convergence board

Yes, you do need to set up the convergence in order to get the picture geometry correct. the antenna and maybe some other settings will need to be restored through the appropriate user interface screens. You will need your owners manual for a guide.

You need to most likely replace the convergence output IC's probably STK392-110's and check associated resistors around it. HD is not mandated for 2009, only digital braodcast it is at that point all analog television broadcast must stop.
