I have PHILIPS TV 29 PT8861/75/R made in Singapore. Please, anyone have a Schematic diagram to help me a fix problem with picture clarity. Thanks to all.
CRT is OK because blue screen and teletext is very clear. But signal from TV and DVD is a shadow and saturated by blue and red color. RGB transistors is OK. Any idea where is this fault. Thanks. R. Djonovic
For the life of me I cannot understand why respected TV manufacturers would change to surface mount parts. Unless the set is very well designed and the Micro/Jungle is extremely well protected and will not fail when the PSU fails due to some crap happening. Or the Line Output Transformer has a BCL winding problem and feeds too much Voltage back to the Jungle I.C.
I will say this however:
I have a huge soft spot for Renesas. I see lot's of sets coming in from unknown Chinese TV manufacturers. Many using Renesas surface mount IC's
I have yet to see one of these chips fail. Despite various Manufacturers using them in as cheap as possible design. Simply bullet proof.
We get lot's of these sets built around this beauty in for repair. Always other problems. LOPTX, PSU etc.
You can't have applied much thought to it then - it's dean simple
It makes manufacture of the set a LOT cheaper. Any manufacturer trying to compete using obselete manufacturiung methods can't survive, unless they use slave labour, or are heavily subsidised.
