OldLes:
Yesterday, a visit to the local amenity site yielded this very tidy looking set. It even had a helpful note suggesting "faulty inverter board, ideal for spares".
At switch on, brief green LED, 9 orange LED flashes (booting up period?) and a green LED. Screen "Wakes up", and an OSD message suggests CVCS-1 input (I think), followed by shutdown.
When I looked inside, I saw evidence of some overheating at the two connection points of the inverter board to the top two of 18 lamps.
I have yet to see if I can find any component faults, but if none, can I simply leave the top two lamps disconnected for testing purposes.
I am inclined to remove the two plastic clip connection holders, and wire these two lamps directly.
I don't see any superficial evidence of damage to the ends of the lamps compared with the ones lower down.
Any comments on this procedure? (If successful, I will be keeping this set for me).

marky mark:
Do you mean the white clips that go into the screen? If so, just replace them.

OldLes:
Mark, the little white clips had overheated, but a repair attempt had been made previously, with an extra thin sliver of copper soldered onto the inverter board's contact point. However, in its original overheat, the temper was obviously lost by the clip, and it was obviously unsuccessful.
I checked all the fuses, compared resistance readings of all the bigger semicons, but found nothing amiss.
So I dismembered the two plastic clips, bent the back part and crimped a short length of wire to each one. I then removed all the overheated connector area of the pcb, and soldered the wires directly.
Connected back up, but still the same.
There was one page from a service note in the back of the set, which says that if there is a fault on the inverter, after five start up attempts, it will be blocked. Maybe this has happened.
I will search for a service manual (or does anybody here have one?) and see what to try next.
I don't have a remote, so not sure if I should buy one. I don't want to throw good money after no money, but it may be necessary.

downunder:
Most likely a faulty lamp. To check,remove the front plastic cabinet section, remove the LCD panel and diffusion sheets under it, to expose the lamp cavity. Best disconnect the Flexis from the T-Con to the panel. Dont need them for this test and you dont want to tear them. At this stage the set is operational but has no LCD panel.Lay the set on it's back, switch it on and wait for the lamps to switch on briefly. After repeat switch-ons you should be able to identify any lamps that do not ignite or light with a pinkish glow. Even 1 lamp below par will trigger the protection on these. Nor can you run them with 2 lamps disconnected.

Kilroys:
You had to do a lamp error reset,
The best way is to change all the 18
lampsocket, becourse sooner or later some of the others
will do a bad connection with the inverterboard.
