Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Hitachi TV 43FDX10B has yellow line with blue curve line above it


It sounds like your convergence ic's are messing up

They have a kit for this tv it is available through local parts distributors
If you can't find it locally just Google HITACHI CONVERGENCE KIT

If you are not good with de-soldering and soldering do not attempt this repair. Remember to replace all the resistors in the kit

If you are not sure about doing this repair you should have your local tv guy do it for you

Hitachi 46f500 screen messed up after welding on same circuit


If you did manual conv. You have to redo it when you replace the bad parts. Them being conv. ic's replace them and check 1/4 watt resistors that are low value right beneath amps. Careful not to solder any foil pads together or you will have major problems. Very common for do-it-yourselfers. Good luck, Russmann.

Has a wave in the picture half way across top of screen


You most likely have a convergence chip bad. In our shop, when we are working on projection TVs, we find that about 80% of the repairs we make are the same problem you are having. You need to replace the convergence chip ( there are 2 of the same chips on the convergence board, and I suggest you replace both ). If you are going to attempt the repair yourself you'll need to remember to use lots of heat sink grease so you don't have the same problem again. Also, try to get original parts, as there are times that the after-market ones don't work well. As a precaution, always remember to unplug the set from the wall before you do any work on the set. Good Luck
