Question about Panasonic CT-27E13 27" TV

1 Answer

Tuner problem? I have this TV hooked up to cable via the coax tuner. Everything worked fine until a couple of weeks ago. I get grainy picture on channels 20-48 but all other channels show flawless picture. I first thought it was the cable and replaced it. Same problem. Then I thought it's the splitter and hooked directly at entry with both old & new cable, same issue. I connected both old and new cable to another TV and everything works great. This is how I go to conclude it's the tuner at fault. Does anyone have any ideas?

This is an indication of a bad ground connection. Since you have replaced the cable and splitter, it suggests an internal grounding problem. If you can solder and can get to the tuner, resolder the ground points within the tuner and update this with the results.

How do you replace a coax antenna port that was pulled out from the back of the tv


On most sets the tuner has to be removed for this to be done-a new fitting or a new tuner can be installed.

If the set has the standard RCA audio and video jacks for input you can hook a cable box or even an old VCR to those and BYPASS the coax fitting--hook up to those inputs--select them on the set and leave set on that input and change channels with the box or VCR.

Much cheaper than replacing the fitting and gives a better picture.

What do I do to get my signal back on my westinghouse TV that is hooked up to dish cable


If no signal via the cable fitting try hooking set via one of the sets of jacks on the back (audio/video or component) to see if coax input or tuner is bad.

If the set works with a DVD etc hooked to one of those inputs and your cable is good--maybe a bad tuner in the set---also if using a box try hooking cable direct to set to rule out the box.

RCA 27 inch ColorTrak Plus. TV is hooked to cable. I can produce the problem by wiggling the coax connector. The screen goes through various degrees of snowy-ness until I find the sweetspot on the coax....


The failure with this TV is due to faulty ground in the tuner that is why when you wiggle the cable connected to the tuner the picture clears up. If this failure is not repair, it will corrupt the data on the eprom until the TV will not power ON anymore.
Check the info from this link to find more info on the failure of your TV.
Let me know if you require further assistance.

Hitatchi 42HDF52 only receives channel 5 and 6 on analog RF input


If you have tried autoprogramming and have found nothing it may be a bad tuner. Is your VCR is hooked up via coax or into a video input? If it is hooked up via video and is working but the coax connection direct isnt it will be a bad TV tuner. Easiest cheapest fix is to use you VCR to change channels or get a Digital Cable Terminal from you cable provider and hook it into video or compnent.

Denon avr-1907 sound from TV stopped working


Help with hooking PS3 to a Denon Receiver. It worked before, but I had to move everything to a different location and when I hooked it back up the PS3 has sound but no picture. I have it hooked directly to the receiver with and HDMI cable (the receiver is hooked up to our cable box which is directly hooked to the tv via HDMI cable).

No Tuner hardware !


The PC must have a cable tuner card installed and connected to be able to record and show TV.
The extender uses the PC for showing the (recorded) TV.

Screen just went black


Think your set tuner is bogus. The other tuner that you used should work, but if it is not a cable tuner configured to your system it will not work either via the rf outputs or the audio video outputs. If that cable box works with another set then you have a real head scratcher on your hands.

No cable signal on 32" flat panel Olevia tv


When you write 'tuner,' do you mean the internal TV tuner or do you have a cable box between the wall connector and your set's input?

If you are connected from the wall to the set, then the sensitive circuitry (it may only tolerate a few volts max video) is damaged.
If your set was a couple of decades old, it might be fairly easy to repair.

If the set was damaged via the cable service, you may have some recourse unless your cable provider has seen fit to absolve themselves from liability, I suspect they have.

I do not know your set but it is not impossible that the video input circuitry for cable and antenna is on a smaller assembly that processes it before reaching the main board.
The latter has obviously survived since you still have the other functions.

Lost channels 2 through 52


I think the low band (Channel 2-6)in your tuner is not working. This could be in the tuner itself or in the band switching circuits. Possibly she deleted the low channels or locked them out. Stargazer
