Resolder the vertical IC that is whats making the CRTs go blank. Its a safety issue where the CRTs blank when there is no vertical deflection. Just resolder the output IC that should cure your problem

High pitched squeal


Hi...

Does the squeal come from the TV cabinet or the speaker?
If from the cabinet , it's most likely the Horizontal high-voltage section of the set.
Find someone that's good with hand tools,unplug the set from the wall outlet, let it sit for a good 30 minutes.
have someone open up the back of the set and dust out and vacuum out any dust from inside the set.
Put back together and try it out.

NO HIGHT VOLTAGE


sounds like the LSB is defective as that controls all the high voltage and deflection circuits. If you go to the following link and leave them a email with your model number they should have a LSB board for your model.

You have got to have a cold or cracked solder joint. Get a strong light and go over the chassis with a magnifying glass. Solder everything that doesnt look shiny but be looking for hairline cracks in the solder especially near the vertical output IC and associated components.

Powers up no pic


You have a bad solder connection in the Vertical deflection circuit. Try re-soldering the vertical output IC and the Vertical yoke pins. You may have to look over the Vertical circuits with a magnifying glass to actually find the bad solder . A hint if the solder looks dull re-solder it.

Volume buttons stuck inside


hi , first i want to say that the tv is not a game it is hazard set very high voltage inside so if you don't have any experience please dn't try to , but you can do it your self just took outlet off and took case off and try to draw the chasses towards you to behind then look inside to the place of the buttons you will see aplastic tips which will push the volume switches that are soldered on the chasses and with your fingures try to push out the plastic tips to relocate it to the original state it is too easy and the please try to be away from the cable that is fixed to the screen cause high voltage is it, refix chasses and cover and give me high rate insted of £40:) regards
