hi dennis more than likely to be the inverter sometimes it will light up for about 1/2 secs then go out but could also be faulty caps in the psu ie bulging from the top rgds dave

Hi Dave,
Thanks for the info,new to this,did a tv course umm 100 years ago,still had valves then.
There seems to be one cap with a raised head next to the two diodes (smoothing?)Could that be the problem?Would it be best to replace the psu board?best regards Dennis.

i have replaced the caps that are faulty and the board is fine, if you can test the caps and find them OC or diff value to spec can save lots of mooney

hi you could change the faulty cap first but to be honest id say it was more than likely the inverter panel .i do have a few if you can get me the number i may be able to help .incase you were unsure the inverter is usualy a long line of tx's on the left side of the screen as you look with the back removed .pr could be 2 panels a master and slave either side let me know if you need any more help.dave

Hi folks,

No-one has yet said what the panels are - Folks can seem to chat happily for ages without any useful input - Just a thought in hopes of some resolution and, time is pressing.

Now awful old, and might pass over B4 any repair - holding on, just fer this one (and for Sparky to make that needy pound, at last) - Chris.

Hi Dave,have changed the cap in the psu,still no joy,would like to try your next suggestion and try changing the inverter board.
Board No. SS1320WA16 0.6 one long panel that slots in on the right of the screen.Have you got one,remembering that Im a pensioner without a lot of the green stuff,thats why Im trying to repair it instead of throwing it in the bin and buying a new one.best regards Dennis.

Hi folks,

Note that no-one has yet admitted to any panel numbers or piccies.
 
Leave it to Davenjax and other youngsters - they have the time to train Turkeys

As a Norfolk chap - and after a famous local demise - have some doubts about eventual success - Chris.

Hi Dave,

Noticed that afterwards - but no piccies - love piccies (LCD or Plasma - too old for anything else) - Chris
