1. Service Manual

2. Try a hair dryer to warm some of the components on the first couple of boards.  It is usually capacitors that cause the problems.

3.  Be careful

4. Keep the external good parts and buy another TV for next to nothing and make 1 good from 2 bad!

Could be a bad cap in the tuner section or AV switch...

Hmmm, check it with the AV port, connect a VCR or DVD player.

Both the RF connection and AV port are the same.

Did you already check http://www.repairfaq.org/sam/tvfaq.htm ?

Great website with lots of info on fixing TV's, symptom oriented. Has been a great help for me! (and I learned a lot from it!)

Thanks for the link, I wil have good look through it later. Welcome to Beoworld BTW.😕

The white flash you get at switch off - does it look like a line across the screen centre the split second you see it?  If so, it's probably field collapse ie no vertical scan  (I'm assuming this set is a CRT type - will have a look when I get a minute) = Brian (Northumberland)

hi,

try to rotate (just a little) the G2 regulation pot and watch to the screen if something appear...

Yes, as Onyx has indicated - turn the lower of the two pots (not the Focus one) clockwise little by little - if it is loss of vertical drive, you will see a bright line across centre of screen, but first mark the position of the pot so you can put it back!  I am assuming that you can recognise the LIne Output Transformer, as this is what we refer to.  Let us know what happens -  good luck = Brian (Northumberland)

More to think about = If it does turn out to be loss of field scan, the next test is to check for 24 volts between pins 4 and 10 of IC2 (the vertical output chip).  If the 24 volts is missing, you would need to check the supply circuit which comes off the LOPT at pins 12 and 4 - two diodes (D39 and D40), two safety resistors (R74 and R75) and the two electrolytics (C44 and C45).  I'm assuming you have a multi-meter and know how to use it!  It can get very interesting - and frustrating!!  Let us know how you get on =  Brian (Northumberland)
