LG 42ld450 repair tips

OldLes:
You say the CCFL tubes come on for 2-3 seconds. ALL of them?
OK, I know it is LG, not Sharp, but my experiance with the latter has been lockout due to failed tubes, where just one, or maybe more fail to light.
I bought a tester, but they all test OK, though they are not quite right.
Just a thought.

Hi Les,

Remember your Sharp well, as I had one with a similar problem - sorted by hard wiring every tube to the inverter panel, as edge connector/panel print - mostly cremated.

Had a look at the LG Power/Inverter board on the Flea, and noticed just two connections to the backlights.

Had similar screen in a while ago and discovered that tubes were connected in parallel. My tube tester can only manage one tube at a time, so guess it's a matter of taking the screen apart to check, if keen.

Other thought is - Wonder if the P/I could notice if just a tube or two wasn't firing up when perhaps the other 10 were - All fun - Chris.
