Good day, i have an intermittent problem on Hitachi TV 60FX20B. Seem to be a convergence problem. Bow on top and bottom of the screen, color not aligned. (look like picutre seen on web related to convergence problem). The tv can be OK few days and suddenly the problem show up. Sometime turn off the TV and turn it back on, problem go away or sometime i turn it off and wait few hours and than it turn on OK. I check for cold soldering or bad connections on boards, nothing found. I replaced 4 capacitors 470uf on the convergence board, no success. When the problem is present the sound is still OK. I order 2 IC stk392-110 for replacement (expected for this week). do you think this will solve the problem?
Is someone has an electronic schematic for that model, other ideas?
Thank Marcel |

Sounds like a plan. _________________ You're over there, I'm over here. |

Make sure you check the bias resistors also. |
