help needed with easy touch tv
jimca007:
stick a pic of th tcon board ( the screen interface board ) just incase someone's got one cheap they can let you have to try
labrat:
will try to get a picture of the board when i have more time as i have to go fetch kids from, nursery now
i must say thank you for all your help im sorry ive been a bit of a dunce its the first time ive ever dismantled a telly at home
im not sure how to check the caps on the power supply, something does appear to be making a popping noise but there is no obvious buldging caps or anything like that
the effect ive been getting is
ive retried all the function buttons they seem to work apart from chan+ which now powers the telly off (wont power it on tho)
jimca007:
I would def be looking at the power supply for combination your describing when you get time up load a good big close up of the psu to see if it's one me or some of the other very talented guys on here recognize incase its one thats got certain caps going down regularly cheers
labrat:
that i can do while i put it back upstairs as i havent put the back back on yet
the other boards a little problematic to do quickly as its under the power board and metal work
whole board
numbers close up
oh and if anyone can tell me how to test parts with a multimeter ive got mornings off for the next few days so i dont mind sitting there testing caps
jimca007:
if you've an old analogue meter you can "charge " the caps by testng plus to plus minus to minus then reversing the leads of your meter and retesting each time you reverse the leads the needle should climb a little higher ( set meter to high ohm scale ) oh aye and make sure the caps are discharged before going near them. If its a digital meter unless its got cap test facility you can really only test for short or open circuit.If the rest look ok and you've got a spare, changing the big smoother cap in the primary is always a good place to start.
