My husband recently purchased a plasma tv and decided to give our 32
inch, 10 yr old, GE tv to our son in his room. After hooking it up, however, the picture was dark and out of focus. After messing with the controls I was able to get a decent picture, but the lettering, logos, guide, etc. is really blurry and out of focus. Should I dust it out, someone told me to check the focus control on the high voltage transformer inside the set. Does this sound right? Any advice would be greatly appreciated!! Thanks, Kiani Pierce |

Thanks, Kiani Pierce Dark might indicate that the high voltage is low. There is a focus voltage and an accelerating voltage ... both must be correct to achieve a sharp image. Dusting it out is probably a waste of time and could cause more grief. At 10 years, it is about at the end of its useful life. I advise that you NOT adjust things internal to the TV. Some repair shops offer free estimates ... check into that. |

I remember about 10 years ago when Thomson started making the plastic around the focus and screen controls the same size as an RCA jack people/kids would try and plug in the Nintendo into the focus and screen control holes and invariably move the controls and sometimes even break them. |
