42H83 Convergence


Yes the convergence ICs need to be replaced, however so dont the six 1.8 ohm 1watt resistors as Toshiba recomends replacing those six resistors when the ICs are changed. You can get the 50H71 / 50H82 Convergence repair kit as the 42H83 is identical to the 50H71 series, so the kit will work for your model. Heres the link where you can get the kit.

Toshiba 42h83


It is common problem in this unit. Toshibia has a service bulliteen to service shops about this unit. It involves replaceing 11 16microfared surface mounted capacitors on the cuircit board known as :HYPERMODULE. I am currently got one of these in front of me now at the shop and the repair is rather difficult .,, removeing the board take alot and then repair the board take some doing ... you must be an expert at soldering surface mount components, i would not recomend this for a non tech. but on the good side your set is repairable.

Toshiba 42H83 Hyperboard 20 minute Wavy Line Repair Snafu I have repaired several tvs, this one has been more of a challenge due to lack of only service manual without a schematic. I replaced the caps on the MVPU14 Hyper board. Those that I found bad with ESR meter. I am fairly certain I botched this the first time using surface mount capacitors and possibly shorted something out when I re-installed. The tv came up with a blinkng red power light problem where the tv would not turn on. I removed and re-worked the Hyperboard using thru-hole parts instead, much easier. I still have the blinking red power light with 1 second intervals problem. In trying to isolate the problem I was able to do the following: A) Removed various boards and powered unit up to watch for changes in operation. B) I found out with the DPC Unit (PD0077) removed and all other boards installed, I am able to have the tv respond to the remote and front panel buttons, have sound, but no picture. I was able to hear a DVD player playing in the background that I had connected. C) No Menu can be seen on the screen, the bulbs don't light at all. D) I still haven't ruled out a faulty Hyper board yet as I don't know if its operation is dependent on having the DPC unit (PD0077) installed. I have not found any signs of damaged components, so now wondering what is the next target place to look at. Notes: 1) TV was working fine with nice bright picture before I started repairing the Hyperboard, so I haven't considered convergence issues and such. 2) I have been focusing more on the theory that the first repair of Hyper board had a capacitor shorted possibly up near top of board by LX229. 3) I did check all the pico fuses I could find and none of them appear open. Since I don't have a schematic, if you suggest checking a voltage, please advise part number and pin to check. I was thinking the 5Volt line should be checked, but not sure where. I do notice a 9V signal temporarily upon power up but goes away when power light begins blinking. Thoughts?
