I had a TV do that about a year ago, the repair man said it was the color wheel inside the tv. I changed the bulb to see if he was BS'ng me and eventually got the manufacturer to send a color wheel and I change it myself, was very easy...TV works fine ever since. Hope this helps
When you had gray screen and flickering you had only one problem - color wheel. After "putting everything together" you have totally different problem, caused by multiple possibilities like: forgotten connectors, cut/jammed cables/wires, lamp not being inserted properly, lamp door not being set properly, disconnected color wheel, etc. Try to open rear cover and redo what you have done. Remove optical block, check everything visually and slowly put everything back. If still no luck - then only skilled TV repairman may (or may not) help.
the color wheel may spin but if you hear noise when it spins it's bad. the jumper is used when replacing one type of color wheel for a nother type. so donot remove jumper unless you've replaced the color wheel and the picture is bad. if the color wheel is good replace the DMD board. if the DMD is not available replace the optical engine.
