|  Jvc AV-48WP74 green tube lit up but not image display I have a AV-48WP74 JVC tv I recently was working on the convergence board.. it had a few blown resistors. Before I started any work on it. The green red and blue had display but the red and green had slopes and bowed. I now have the red in line with the blue in the convergence menu. But now the green wont even show in the convergence menu. All tubes light up but the green will not display images/picture? I have checked all connections but on this TV the blue and red tubes are T'd into the green circuit board on the tube. What could be the problem? Blown resistors or circuitry on the board attached to the green tube? | ||||

| Re: Jvc AV-48WP74 green tube lit up but not image display You likely pulled something loose or damaged something while working on the convergence. Go over it more carefully. Note that we have now begun moving vendors to the new pull down option at the top of the forum pages. You will find it between "Shack Shopping" and "Glossary". This will represent a great improvement in the vendor reference database, making it easier than ever to find what you are looking for. Contact me with any suggested entries, category recommendations, or additional information about the vendors that we have. If you are a vendor and want your company listed, there is an option to provide us with the information. | ||||

| Re: Jvc AV-48WP74 green tube lit up but not image display I some how I had cracked the whole circuit board on the green tube. I was able to solder her all back together. Now i have picture again. But now i still have a slope in the green display and two blown resistors on the convergence board in the green section. I am aware that is probably the problem but i dont know where to get these resistors. I know one is a 220 ohm. and the other says 1.8 ohm. | ||||

| Re: Jvc AV-48WP74 green tube lit up but not image display DigiKey and Mouser are good sources of resistors. Just about any electronics supply house should have them. You might check with B&D as well. Note that we have now begun moving vendors to the new pull down option at the top of the forum pages. You will find it between "Shack Shopping" and "Glossary".
