Question about RCA F27650 27" TV

TV won't stay turned on, no picture, started making high pitched noise

We used the TV yesterday AM without problem. In the evening we found that power button light on front of TV would flicker briefly then go out, no power to the screen. Tried turning on manually and with remote. We tried unplugging and reconnecting as suggested in the manual, no change. Then it started making a high pitched noise which stopped when we unplugged it.

That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing. In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's You'd need to take to a tv shop and have it checked out. Stargazer

The TV will bring to turn on but then it sounds like it loses power and makes a high pitch noise and powers off, no picture ever comes on the TV, the screen stays black the whole time. The TV is a RCA...

it could one of two things. The power supply is failing which is most common. Or the picture tube is gone. Both would most likely cost you more to fix than the TV is worth. Call around and get a few quotes. Good luck

Need the code to set the technika remote to ma toshiba telly

Maybe you could try the auto-set. Found this using google:
Auto code search

1. switch on the TV and select a channel eg. Bbc1 on the TV itself
2. press the appropriate device button eg. TV
3. press the green SET button for approx 5 seconds until the red light comes on.
4. release the green SET button and point the remote at the device to be controlled, the remote will emit a test signal about every 2 seconds.
5. when the TV switches itself off briefly press the green SET button to store the code found.
6. when the red light goes out the search is ended.
7. try out the remote if it works follow the same steps to set it to other devices eg. DVD. If it does not work follow the steps again.
cover other remote sensors on other devices when setting the remote.

After a power flicker our TV Has a large black square in the middle of the screen. Problem is that the commercials are AOK but as soon as regular programming box. HELP!!!PLEASE!!!

You have the closed-captioning turned on and set to "text" mode. It probably got set this way because of the flicker. Use the remote (or front panel menu buttons if this set has them) to get into the closed-caption settings. Turn captioning off and the box will be gone.

In case you're curious, the reason this happens is that the set clears the screen where the text will be displayed, but there's no text. On programs or channels without captioning the box disappears.

When my rca 36F530 tv is plugged in it makes a high pitched buzzing noise picture does not come on

There is a short circuit in the high voltage circuit. the transformer who helps to create the high voltage or his power transistor is damage. replacement needed. the repair is not expensive, because the parts are average repair. Ask for an estimate.

A shorted horizontal output transistor or shorted flyback. If the flyback is shorted replace also its HOT.

High pitch noise from the flyback

You can tell to some extent what it may be by listening carefully and trying to identify the location. If you, remove the back cover of the set; stay away from danger, just listen to where it seems like the sound is coming from. If it is coming from inside the high voltage cage it is the flyback. If coming from around the main power transformer it is one of the power supply parts.

High pitch buzzing.

Hi there
Let's make ur problem a bit clear. "white lines" how? where?
meaning retrace lines with full raster or a single vertical line?
buzzing sound? without even turning the power switch of the TV to "ON" or when u just plug the power cord?
I'll check for schema, mean while can u tell me where the resistor leads to? is it a fusible resistor? if so , to which area the resistor suppliers power?

Turning on TV after power outage

Not sure what you mean by "older", but I assume it's a CRT display. It takes some time for a picture tube to come up from a completely cold start. It has to get all of those electrons hot enough to start flying around, and also build up a high voltage on the screen. You don't notice it in normal operation because the power button doesn't really turn everything off, but just puts the set in standby mode. Unplugging, though, lets everything cool off completely.

If you're talking real antiques, with tube-type amplifiers, then the warmup time could be even longer. I remember as a kid watching the blank screen for a couple of minutes before a picture appeared.

What you describe sounds like normal behavior for a CRT television. Not sure what's up with that flickering red light, though.

Letterboxing: The top and bottom of the screen are cut off I originally obtained this TV from my Bro who passed away from cancer at age 31 a few years ago & I was never able to find out what he did with the manual. However, I was able to find a manual online but after viewing it, I still wasn't able to find the info. that I am trying to obtain for the correct settings to get rid of these black margins at the top & bottom of the screen. I am trying to find out what video output format is supported by this TV model, as far as the resolution and output format, specifically for a Cisco or AKA Scientific Atlanta 500GB HD-DVR through Cox cable? My available settings with Cox cable & the DVR I have( Cisco or Scientific Atlanta 500GB model)are the following-Resolution:480i, with output format of either:Zoom 16:9 Pic or Letterbox 16:9 Resolution:480p standard, with output format of either:Zoom 16:9 Pic. or Letterbox 16:9 Resolution:480wide, with either output format of:Stretch 4:3 Pic, Preserve 4:3 Pic or Sidebar 4:3 Pic Resolution:720p wide, with output format of:Stretch 4:3 Pic, Preserve 4:3 Pic or Sidebar 4:3 Pic and finally, resolution:1080i wide with output format of:Stretch 4.3 Pic, Preserve 4:3 Pic or Sidebar 4:3 Pic? Everything worked fine with the screen size when I had a 160GB Motorola HD-DVR with Cox under the video output settings of:resolution:480i and video output of:Zoom 16:9 Pic until, I grew tired of constantly running out of space & had them switch me to a 500GB HD-DVR. They were supposed to install another Motorola HD-DVR but just with 500GB version but when the Cox maintenance employee showed up to swap them out and install the 500GD HD-DVR, he only had a Cisco/Scientific Atlanta 500GB available on his truck, which is I guess what they use for the Contour service but he attached a filter to the back of the coxial cable to make it a regular HD-DVR without Contour(even though they tried charging me extra for contour for 3 months before I finally got that straightened out since the maintenance workers & billing dept. are often not on the same page as I found out at Cox. I have tried calling Cox for support & they say that I need to find out & know my TV's video output settings. I explained to them that it worked perfectly fine just weeks ago with 480i resolution and output format of Zoom 16.9 Pic before they switched to the Cisco/Scientific Atlanta HD-DVR from the Motorola DVR and that I didn't have the manual and I stated why and they basically said, too bad, figure it out yourself. Can someone please help me out? I have the TV set up for the correct zip code, cable box-Yes, the cable box output channel-video 1/Aux (since that is what the TV manual I read online said to use if you are using the 3-color coded cables instead of the coxial cables to plug in from the TV to the HD-DVR) & I have the Cable box remote control code set to code 008 (Scientific Atlanta) that I verified to be correct by checking it through the TV's automated code search. The serial # for the TV is:C306B2084 and the Chassis # is:ATC113BB1 and its the 27" RCA Entertainment Series Guide Plus Gold Gemstar that is X-Box ready. Thanks so much, Todd
