Question about RCA F27650 27" TV

1 Answer

Tv turns black and white

Hello, I have a 27" RCA, it's about 4 years old. When I turn it on it's fine, but after it's been on for a while maybe a hour and half it turns black and white. If I leave it on the screen becomes totally distorted. Could the tube have gone bad?

Re: tv turns black and white

No, the tube is not bad. There are a couple of very small surface mount components mounted by the main microprocessor that could be causing what you are seeing. They are very small and quite hard to unsolder and replace without losing them. The set should be serviced by a qualified tech familiar with the new RCA chassis.

No picture or sound

Does it make a squeal sound while plugged in to power? If so, possible horizontal output shorted. $150-$200 about.

No Picture - Black Screen. Intermittent Sound

I repaired an RCA same model with a very similar symptom. I found bad connections on the printed circuit board at L411 and L 412 (coils) in the horizontal drive circuit. Give the set a good Fonzie ( Happy Days) smack on the side and see if it comes on. LOL. Bad connections are common with that model. It is probably worth fixing and no, lightning didnt do it.

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock. Be careful !!! Stargazer

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
