Question about RCA F27650 27" TV

1 Answer

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.

    My RCA has been turning itself off and on for a few days now. It has a history of the picture shrinking horizontally then snapping back to full size. Sounds like the transistor problem mentioned here. My question now is: Is it worth fixing? It's 6 years old.

    lameastra, we just encountered the same problem as you. Our RCA F27650 32" TV was working this afternoon. When we got home this evening and tried to turn it on, the TV would not turn on and the power light blinked green several times then stopped. We also heard a clicking sound each time it blinked. We tried unplugging everything and turning on the TV, but that did not work. The toll free RCA troubleshoot department has been no help either. We would greatly appreciate any assistance on this!

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

I turned on my Samsung PN51D7000FFXZA recently it had no picture and started making a high pitch buzzing noise coming from inside the tv. What could be causing this?

Unfortunately, it's probably the power supply board. Usually one of the transformers or coils on that board.

Get a quote from a TV repair shop, should be able to quote without bringing it in. Check reviews on the repair shop.

Don't open it up yourself! There are hazardous voltages even when the TV is unplugged!

Barb, noise may be from a power supply/ transformer on it's way out.

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?
Regards

High pitched noise

The power supply is starting to fail on your LCD. The noise you hear is because the circuit is trying to provide the proper power to the rest of the circuitry and is forcing itself.
The noise does increase if you tune to an HD channel because of more demand for power for a brighter picture.
Let me know if you need further assistance.

Hi there

Try replacing the electrolytic capacitors in the power supply section. I started with replacing (2) 860uf 180v caps just after the bridge rectifier and continued along the circuit. Some (15) or so capacitors later,it finally cleared the the horizontal bars and lines and the high pitched noise. It also fixed another intermediate problem of no video, when turning on the power.

Here is a picture of what they look like:

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

tv screen is stretched too wide comin back from a week vacation, i turn on my rca f27650 to play xbox and i realize that my screen has been stretched out of proportion! i cannot see sides of the proper picture. i swith it to tv mode and the channels on the top left only show half of the first number! after trying to play around wit the menu settings to see if anything can be done to play wit the parameters! i went on my xbox 360 because i knew that there were settings in there to change screen fittings! what i found as a success (somewhat) was that when i changed the xbox screen format from normal to widescreen, the picture was formatted and actually fit the screen....kind off! the screen was no longer stretched and i was able to see the whole screen. even wit this somewhat succes, unfortunately the corners of the image were warped and appear compressed to fit format! i have tried troubleshooting from online but i have been most disappionted. ~ i have kept it unplug for hours / days to try a reset.fail ~ i have researched on how to acces the service menu for my model so i can adjust it but i seem to be finding only instructios for the generic rca service menu! the steps: hold menu, press release power, press release vol up, release menu i havent been able to get to the service menu at all! i thought that i might have already activated it but the screen jus didnt let me see it so i went and tried to acces this generic service menu on my other rca tv! it was a truflat rca model f20t10 ! similar guidpluss menus and all but i believe a bit newer! even on the rca f20t10 i was still unable to acces any service menus!...if you got any info on how i can fix an fit my screen please please let me know! thanks in advance
