Thomson DTI550 set top box problem


Hopefully those of you who still own their DTI550 had it operational this last weekend and picked up the download that fixed this? If not, it should be repeated some time soon. So don't throw your 550 away yet!

Intermittent vertical jitter on mistubishi tv 65000


Good Day, sdkhanmd; Replace C2P05 100 UFD 16 VOLT off pin 3 IC2P01 and IC2P01 part #270P466020 (9 volt regulator). Both are on the signal PCB. Also, check other caps in area for leakage. Hope this was helpful, this common for this model. Good Luck, big IRISH.

Issues with the big screen


This is essentially a convergence problem and will continue to get worse. If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heatsink and should be marked STKxxx.

Keep us posted on your progress.

Jittering screen


Chassis will need to be pulled by a skilled technician.Some specific area hand-soldering is needed and the STK convergence IC's need changing w/OEM or better quality parts.You have a good set worthy of repair.
