Question about Sony FD Trinitron WEGA KD-27FS170 TV

1 Answer

Intermittent reception problem

When my tv is first turned on, the cable feed is inconsistent, resulting in a scratchy, static sound with no reception. It will cut in and out in a staccato fashion. When I jiggle the cable which leads into the tv, even when the reception is clear, I can create this interference. Once the tv is "warmed up", it usually goes away, but can happen again after any length of time for no apparent reason. I know it's the tv & not the feed because other tvs work with no problem. Maybe there is a loose connection inside? Is it worth my while to have this checked or is it an expensive problem to fix?

I think you have a loose connection inside the tuner. Sometimes this can be repaired by removing the tuner and soldering the connections. Sometimes the tuner will have to be replaced. The cable connector which sticks out the back of your set could be broken loose inside the tuner. This type of problem is very common. You never know when it's going to happen. IT will change with temperature. You need to have a technician check it for you. Stargazer

Volume switch on Panasonic radio has scratchy static sounds

Sounds like oxidized contacts.
If volume is a turn-knob, then wiper-track (inside potentiometer) is worn.
If it's a PTM (push-to-make) standard button, the button contacts may be dusty/dirty/oxidized.
Suggest you:
buy a contact cleaner such as Servisol,
open case,
identify controls
and squirt liberally to wash out any gunk.
Move/press/wiggle scratchy one to help 'scrub' the contacts clean.
If this doesn't help try have control replaced.

Records snow/static - intermittently

Intermittent problems like this really suck.
I have a simular problem on my Toshiba DVD recorder. Once in a while it just doesn't record anything at all.

Unfortunately, there really is no solution. It sounds like a glitch in the unit to me. Wether or not it's present in all the units of that model or just yours, only Panasonic knows for sure.

Tv connector cable plug slips out

you need to replace your wall cable outlet. This can be purchased at any Radio Shack or Home Depot store. You will find two mounting screws , remove them and you will have access to the junction box. If the cable system was installed in the proper manner you will find a double male connector attached to the face plate by a single securing nut. Remove this nut and replace the double male connector. simple job, hope this was a help to you.

Scratchy sound

Some channels broadcast on diffrent sound channels and power. I would bet the ones that have static sound are the high frequency channels that broadcast in dolby surround 6.1 or are sending High Def signals.Before tearing it down I would check to see if the cable box or satellite reciever is out of date. If they are the company you go through should replace it for you. This should fix the problem. If not then you have a problem with your sound sending hardware.

1996 RCA Color TV model G27720tn

If you are on cable, first run the cable wire from the wall directly to the TV, eliminating any cable box and/or VCR. If channel 2 is snowy but the rest (especially 3-6) are clear, it is most certainly a cable problem and not a TV problem. The TV uses the exact same circuits for channel 2 to 6 (VHF-LOW) so if the tuner was bad and 2 was snowy, 3, 4, 5 and 6 would be snowy too. Bring a second TV into that room, disconnect the cable wire from the RCA and connect it to the second TV. Is channel 2 on the second TV as snowy as it was on the RCA?
