Mitsu CS27303
This set when first turns (most of the time) turns on with no sound
no osd, good video,channel change. When I push the menu button screen goes blue and that is all. Pushing it again may restore it to its previous condition Does this sound like micro processor trouble? I have read alot of posts on this faq site about these sets having alot of bad caps. Once in a while leaving it off for a day or two,(unpluged from power.) it will come on working perfectly until menu button is pushed, then it goes into the blue screen mode and when it is pushed again goes into the above described action.. |

Mitsubishi T.V.'s are known for all kinds of bad electrolytic
capacitors, look closely, can cause many problems. Rono. |

Every polar electrolytic cap needs to be inspected for leakage and any that
are in circuits relevant to the problems need to be ESR and capacitance tested. You will find about a dozen leaky caps in this model. Don't bother to do any real troubleshooting untill the leaky caps are changed, the board is cleaned of residue, and repair to bad traces and connections is made.
