If you would give make and model number we can give you very clear instructions. However, here is general idea: Go into on-screen-menu and make adjustments to brightness, color and contrast, etc
What is your question? So, you replaced the lamp? Why did you do that? Was the lamp indicator showing? Did you follow exactly the owner manual instructions on the replacement procedure? If the set
The loss of picture and raster is most often associated with high voltage failure. The high voltage circuit is driven by the horizontal output amplifier/transistor or module. Thus, the repair will involve
Without the model number I can only give some general comments. Warranty lasts one year; if it is under the one year mark they may help you again. If over one year I think they will say no deal to warranty
Seems you have a convergence circuit gone bad. The cost of repair is always around $300 plus. It requires replacement of two Integrated Circuits called STK392-xxx chips and some testing. Since the
