Re: samsung LE40B551A6W black screen with sound
the tube was from ebay same model of tv. i shall be dismantling the tv again tomorrow checking bulbs and connectors incase anything loose causing a short.
if i take front off down to the tubes can i attach power invertor board and power up. would this be safe to see what happens or is this a NO leaving the tubes exposed
thankyou for your input and also to others who have given me advice on this tv...
