white flickering lines & snapping noise

1993 27'' Mitsubishi....when turning tv on, white flickering lines flashes horizontaly with snow as well, and when flickering sound snaps out of speakers. When warm enough it stops but it keeps getting worst for the past 6 months. Now it can take up to an hour before the flickering and snapping sound stops. Opened up the back, cleaned everything up very carefully with small paint brush to get all the dust out, but in vain. Are some solid connection loose? Should I just get rid of it.

Thanks a bunch!

Power Module Adapter for a P42 Vizio Plasma HDTV

 I acquired a model SP42A on EBay with a power outage problem.  So I acquired another P42 with a damaged Plasma screen but it's newer by almost two years.  The power module adapter board has all the same outputs, size for mounting, but the total amperage output is less then the original board by almost .5 AMPS.  It's a newer design, I mean completely different layout !  Should I use it?  Is the older model in need of that extra power ?  The difference....4.5 Amps VS  5.0 AMPS, and 300 WATTS total VS 330 WATTS total at white scale.

availability of RCA television parts

I purchased a 38" RCA widescreen HD TV model F38310YX5 in Nov 2002.  It recently shut off and smelled hot and would not turn back on.  After taking it to the television repair shop, I was told that the two parts needed (part #248598 High voltage block and part #250789 Fly Back)were no longer available.  I called RCA and was given a case number and told to look on internet for parts because they had none available.  In shopping for a new television, I was informed that this is a common problem with RCA and that it was thought that they had a class action suit against

Mitsubshi model VS55601

Our TV has intermittent white bleeps while playing.  Also if there is a power outage, it takes the tv 12 to 24 hours to get the picture back even though we get the sound.  What can we do to fix this?  We have 4 cable hook-ups and the other ones don't do it.
