Convergance Problem Troubleshooting

I'm having convergence problems. I pulled out the board that has the converg. IC's and I'm getting some new IC's soon, but I have read in other threads that the resistors may also be a problem. I see a bunch of big, probably 1 watt, resistors around the area. Is there anyone with a schematic so I can test these resistors. I guess I could de-solder the end of each resistor, but that would take a while. Service manual or schematic would be of great use.

Its almost always a convergance inverter that has burned out. The IC chips as they are called aren't too cheap, Even the repair shop would suggest a new tv as a cheaper route in the long run. To make your set reliable again the convergance board needs to be rebuilt with all new chips, and pico fuses.

Convergence problem


Usually what happens is that the convergence IC goes bad or the fuse going to the convergence ic goes bad. Pico fuses they are called sometimes open up. You may want to open it up and pull the board out and check the solder connections on the convergence IC. Sometimes these get fractured or cold soldered and aren't making connection to the PC board.
Let me know if you feel comfortable with pulling TV chassis out or pulling the board that has the convergence IC on it out. Then you can resolder convergence IC OR replace it.First thing i would do is check to make sure there is between 22vdc and 25vdc on the fuse or the convergence IC. Let me know if this helps out any.... Sincerely HDTV GURU JAY

Hi,

Hitachi Convergence

Check out the Convergence Gallery. If you see the colored outlines or color shading as in the Gallery, you have a convergence problem.

The repair for a Hitachi requires the replacement of the defective IC or ICs and any damaged or smoked resistors. Some models don't have a separate convergence board and the board is not usually available for the ones that do have a separate convergence board. Usually there is little alignment required after the repair. If you play with all the adjustments before the fix, hours may be spent re-aligning.

If you change the original ICs with substitute "new and improved" parts that are talked about in the blogs, you will probably create problems. Use the original ICs and resistors.

Don't monkey with it.

This is a delicate and difficult repair. If not done by someone with some electronic repair experience, the TV will likely end up as junk or cost considerably more for a tech to fix the damage done.

If you live in Calgary, call me. If elsewhere, find a competent tech.

Convergance chip


Thats the regulator chip for the convergence circuits thats the one youre most likely needing, as your chassis doesnt have convergence ICs. You can get that IC at the following link and they will provide free installation instructions and free on line tech support just in case you need assistance. Here is the link.

Tv is dead


Hi, Yes! the convergance board can stop the unit from coming On. No need to change the board, just change the ICs. This is what it looks like,you will have to remove the board from the unit take note of the wires before removing them, -794a500.jpg
