My luxor keeps turning on and off

SOURCE: toshiba 42wt29b. screen keeps turning blue

MMMM Hard call here. The fact that it does try to come on blue maybe an indication that the power supply regulator circuit is good. It could also be a shorted blue tube and when it comes on its overloading the screen drive and the set goes into overload protection shutdown. The real way to see Would be to pull off the blue crt socket as well as the Hi Voltage lead on the crt and see if the set comes on without blue. If it does Your gonna need a pict tube. If it dosent then troubleshooting along the switched power supplys would be neccassary.. BUT I advise you THAT IF YOU HAVE NO EXPERIENCE TROUBLESHOOTING TV SETS PLEASE SEEK A PRO TO ASSIST YOU AS THERES VERY HIGH VOLTAGE INSIDE THESE SETS EVEN IF THEY ARE UNPLUGGED. GOOD LUCK

Attempt to start without sim. Try without memory card as welll.

I generally fix this by re-seating the bulb housing. Take it out and put it back in. Look for cracking at the base of the bulb on the mirrored surface. It could be a barely functioning bulb that isn't busted, but can't initialize. I would take it to a shop that has the same bub type in a housing and make a quick switch.

This is caused by the BATTERIES insert some top quality one better than durcell .
remove the memory card then do a reset which is the hole next to the trash can button you need a papper clip or a pencil shame the companys gone bust .
hope this helps
