The standby is blinking continuous . this indicates that there is no reply from the jungle IC (data bus is busy), shorted to ground or held high or the IK video path is defective. This is according to sony's trouble shooting. I can't find this chip or device and Dont even know if its in fact bad. Can any one help me in this adventure.

The Y/C JUNGLE chip is IC301 on the M board. It's the second largest chip on the board. The M board is mounted vertically in the middle and on top of the D board, which is the large horizontally mounted board in the middle of the set.

What did you take apart! Did you merely remove the M board and reinstall it? If so, that means that the whole problem was a poor connection!

In order for me to take apart the M board I needed to remove at least seven connections. Once back together the T.V worked and then quit again. When I opened the back of he T.V up to take a second look, I noticed a cable that was half connected. The cable that was half connected is located on the stem at the back of the CRT, I think it has five wires and is an inch in size connector. Once I plugged that back in, it worked. It could have been a coincidence but I have not had any problems sicnce.

The first step in troubleshooting is to conduct a thorough visual inspection. Well done!
