| Re: CRT based RPTV Convergence Repairs Icaillo,
First off thank you so much for all the detailed information on repairing convergence problems with replacing IC's and resistors. I have a Hitachi 57F500A, rear projection TV with the infamous convergence problem. Bought the SANYO IC # STK-394-160’s kit with the resistors. I removed the old STK392-150 and replaced with the new 160’s. Checked and metered the resistors on the board and all seemed fine. Installed everything back together and I get no video and no sound.
The original problem was a convergence issue but I had video and audio. After replacing the IC’s, the TV turns on but no audio and no video. What did I do wrong? Do I need to replace all the resistors? The soldering on all of them looked fine. I recently did this same repair on a 55” Toshiba and it worked like a charm.
Please help. |
