Power supply failure, scans failure, short in one of the circuit areas, and or bad CRT causing possible protection shutdown.

If you can have the service manuals, have the test facilities, and have a lot of TV service experience you should be able to service the set. If not, I recomend sending it out for proper service.

No picture, no menu, black screen, no raster, sound ok


From your detailed description, it sounds that the main chroma processor IC has damaged. Raster means nothing, but the lighted screen that appears, when a TV is switched ON. For some brands, there will be a blue screen; when there is no signal input, and some others will have a bright white screen with some snow.
I advice you to contact any service technician, to get this TV repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

Nothing appears on the screen when turned on.


Do the obvious first, and pull the board out and check all your solder grounds...especially on the verticall IC. And check the 200,250 volt 1Mf to 4.7Mf elctrolytic caps on the deflection part of the board. This is always a good jump to start the repair work. And leave the more complicated stuff for a TV tech.

Visual transparent lines at top of picture


You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer
