I have a Toshiba 50HX70... I fixed the convergence issue around 6 months ago. Now the sound does not work... I turn it all the way up and you barely hear anything... I did move it recently, did I know...


Best best would be to try the following:

Start with taking the back cover off of the tv.

1) Verify if you can hear any sound whatsoever out of the speakers. If so, that would indicate that the speakers are still connected to the circuit board. If not, then trace the wires from the speakers to where they plug on to the board.

2) if you hear sound (hiss) in the speakers, but not the audio signal from your program you are watching, then look to ensure all connecters are fully seated around the RCA jacks in the back.

If those two do no produce results, then could be a solder joint on the board finally failed after moving the tv, or the amplifier for the speakers has failed. If you hear sound though as in step 1 above, i would doubt it is the amplifier IC.

Remote and volume not working on toshiba 50hx70 after changing out convergance chips


Howdy,
It sounds like you may have not have plugged something in or one the connectors are not "seated" or securely properly/tightly.
Make sure there is not any cables and modules are properly (tightly) secured and tightly secured.

Good Luck, big IRISH.

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

Hi, you`ll need to call the tv guy then, you have a short in one of the power supplies, or possibly broken solder connections, either way the board has to come out and board repaired or parts changed, BMW Rider
