How do i Fix the complaint of no picture and only plain raster. CD playing is O.K. Philips CRT TV, Model No.21DI4210/94R

So many possible reasons from part failure to faulty connections inside.
I would imagine it has OSDisplays so are they there and working OK.
My only thought other than a service engineer would be to turn it fully off overnight then try again but I would think its an age related problem (heat causes bad connections or part failure)

sorry thats all I can think of.....

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".

Sharp tv valeo no raster osd ok

Check and replace the video-IF IC. In most cases, this stage circuit will be a combination of its chroma IC. If so, that IC should be replaced.

Picture cutting after 5-10 min-raster OK sound OK

The vertical ICs on this particular model have by now bad grounds. You will have to resolder this, and check any and all grounds on ICs mounted on heat sinks! Bad grounds are common and plentiful. Good Luck and thanks for asking!
