Units made around 1999, have seen common CRT failures. Model # TXJ2750X/XAC, Chassis # K51A. Units come in with 2SD1880 horizontal output shorted, & CRT arcing orange inside tube, replace horizontal output, set works for a couple of days, & the replaced CRT also starts arcing. Sometimes the CRT's lose the vacuum, other times, they arc, for no aparent reason. Sometimes, if you hit the CRT hard, the problem will show up. Anyone see the exact cause for this fault? High voltage & B + is fine, & horizontal output runs at normal temperature. Dani.
