Its power regulator section circuit ahs the fault. If you want to repair this section, you must have through knoledge in electronics and work experience. Most of the components in this section are very dangerous to touch. It is fatal for an unexpereinced one to try to repair this section. If you are confident, download the repair manual to your set from internet and follow.
The convergence ICs have failed. You can get the JVC AV48WP74 - AV65WP74 convergence repair kit from www.tvrepairworld.com which has the ICs and resistors plus the CD with detailed repair instructions.
It not the bulb,it still good.Ur tv have a problems known as convergence,"have colors shadows,colors misalinement,picture look like 3D" it dead.This convergence problems it happen to all DLP TVS sooner or later. The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts in the convergence board must be change to fix this.The shop will cost u $300-350 for parts and labors.
Yes unplug the TV for 5 minutes and hold the menu button down while powering it up for 1 minute then release the button and press volume up 6 times followed by down volume key 4 times.
You have set the DVD to progressive output for your big tv. The little one will not accept this.
Your manual will tell you how to reset it. The remote may be needed. Reconnect it to the big tv and check the menus.
Yes, one of your convergence IC's have gone bad. They are located on the convergence board inside the tv and there are two of them. They are inexpensive and easy to replace if you know how to solder. Watch out for the JVC booby trap sensor on the dvi input card. Don't run the tv with the back panel off unless you have disconnected the DVI card from the main board. I would even cover the little sensor with black electrical tape. Then it is safe to work on the tv when it's open and on. Well safe for those who know what they are doing.
