Toshiba 50HX70 Convergence reset

Hi,

Suddenly I get a red shadow over the pic. Managed to reset convergence manually for all numbers (1 to 9) except 2 and 8.

The red line refuses to go further right to merge with the blue and the white crosses.

Help please?

    Same problem for a 2nd time. First time cost $360 for repairman, just 2 years ago. It happened again last night. Is this something you can do yourself?

Ghosting or a 3D image. A yellow and blue ghosting or shadowing image. Looks much like the top picture in the "picture ghosting image" entry. Is this a convergence problem?


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Did you check the two pico fuses on the G board? Usually at least one will blow when the original ICs failed. I am attaching a pic that shows the 2 pico fuses on the G board.

Toshiba convergence


There are kits available online, which include the chips and the soldering iron too.......Just a word of caution, convergence chip replaced is more difficult on Toshiba #1 the chips face other boards that must be remove first. the main one is the convergence generator (which the sheild is soldered in placed) Also the signal board (which is what everythings mounted to is very fragile)..............Good Luck
