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

Hi I have a Toshiba Regza 55" flat screen TV Model 55ZV65OU. Yesterday we had a power outage a quick flicker Off the power then on came the power but my TV won't turn back on.Note I use a power bar w


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

No Picture/No Sound


This is very possibly a power surge, can you tell me how many times the light blinks, you probably have a bad power board now if you had a power surge.

Booting Problem


Could be a power supply problem but suspect its a problem with the motherboard. Unless you have a spare power supply or testing equipment I would suggest you take this to the local repair shop. For $30 they should be able to give you a good idea if the power supply is shot (cheap fix) or the motherboard (more expensive). Be aware that I also found lots of cases where a bad Emachine power supply also damaged the motherboard as well.

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
