Runs for a while, then locks up. No functions work. (*All functions inop*)
*Autoprogram slow*, one channel per second.
This set uses the MTT004. Found C677 (5V run filter) and C654 (11V Stby
filter) leaky. Excessive ripple was locking up the microprocesser. Other
MTT modulles have similar capacitors but the nomenclatures are different.

> When first turned on the OSD will stay on with the channel number and I1
displayed. After a bit will change to I2 and then I3 and then all the
functions lock up, you can not change channels. Then after a while the TV
will shut off. Sometimes the TV will turn on by itself.

> I have resoldered all connections in the MTT003 and replaced the 5
electrolytic caps in the MTT003, replaced the 15uf 50v cap C11 in the VIPUR.
I have even replaced the keypad.
