I have an RCA CRT TV, 19", Model #F19426. Lately the video contrast (or brightness) keeps changing. There is no regularity to it - sometimes it stays either brightness for a long time and sometimes it keeps changing rapidly (flickering). Sometimes if I bang on the case or wiggle the cable input connector, it will temporarily revert to the original contrast. The audio is not affected.
If it's affected by wiggling the connector, it must be the connector's problem. You'll need to get it repaired (or probably just replace the CRT; hardly anyone will service those anymore). RF modulation is an option too, but probably not preferable because of the lost quality.

there is a casing stat which senses overheat. this can be due to lack of ventilation if a built-in type or a fault with the fan

During a recent move the remote was lost. I have the 6420FF in my son's room and trying to set up dvd and wi console set up, but cannot adjust tv via menu button on tv. Is there any way to set-up game system and/or dvd without remote?
