Advent HT2751A display no good until after 1-2 hour warmup - maybe
All inputs, will not display video, although the audio does come through. When in RF/TV channel mode, the screen shows a picture with lots of horizontal tearing. Eventually it just displays a random, static spotty colored picture. After a good hour or two, the set may actually begin working - although the picture quality is not perfect by any means. What info I've gathered suggests it's power supply/flyback related. It's strange that heat actually helps the set begin working correctly. I believe the problem to be more related to a bad IC than a power problem. From what info I've obtained, this problem is not unique. I have to believe someone out there has faced and fixed this problem.

After 3 years, I finally decided to open up the TV and do some troubleshooting. Found out the problem, It was a blown capacitor Location C554 Capacitor value is 2200uF 16V - costs about a dollar to replace yourself and the TV works brand new.

the following steps must be carried out in the correct order:
Turn on the radio - the word "SAFE" appears in the display.
Press the FM 1 and AM buttons simultaneously and hold them down until "1000" lights up in the display. Release the buttons! Do not, under any circumstances, continue holding them down or press them once again. This would cause the radio to consider the number "1000" to be the input code number.
Use station buttons 1 to 4 to input the code number on your Radio Card. Use button 1 to input the first digit of the code number, button 2 to input the second digit, and so on.
For technical reasons, the first digit can only be a 1 or left blank. The following three digits, however, may be any number from 1 to 9 .
Once the code is shown on the display, press the FM 1 and AM buttons again simultaneously and hold them down until the word "SAFE" appears in the frequency display. Release buttons! Soon afterward, a frequency will be displayed.
Should you inadvertently input the incorrect code number in attempting to release the electronic lock-up, the word "SAFE" will appear in the display - first blinking and then continuous.
You can now repeat the entire canceling procedure once. The number of attempts will be shown in the display.
If you input another incorrect number, your radio will be locked up for approximately one hour . The radio will not play. Leave the radio switched on. After an hour, the display with the number of attempts goes out and you can cancel the electronic lock-up as described above.
This cycle - two attempts, one hour lock-up still applies.
This is the best solution for your problem as a 40 year experience with wires etc.
Go to the source of your cable signal connector .
Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires.
Hi, although I have all sony tvs in my house, every room brand new, when there broke there like a opened bottle of wine ,FLAT, no good!! A 27 is so cheap its worth buying a new one. UNLESS you live where you have friends that fix them on the side. I do and if you ever get to seethe inside of the tv you will wonder what your paying for there is only a few parts in them now and my friend chks them with a machine in 10 minutes if it is worth fixing he has the parts on the shelf and it must be under 100 or its going in the barrel. I have had 1 fixed 10 minutes still good other 1 he threw it out. That's all I can do for you from here, sorry, good luck, Frankie
The green steady power light is a good thing, how old is the TV?
If you are routing your audio and video through the audio receiver, make sure that the inputs are correct on the display of the receiver, ie. IF you are planning to watch your DVR and it is hooked up on Component 1 for video and Coaxial 1 for audio, make sure that the receiver is still programmed for this in the input of TV/Video 1 or whatever the input. I have ran into this on countless occasions, simple fix, but a headache until it is tracked down. Double check the connection to the TV as well.
Hi. You could look up reviews. I personally usually never offer advice on choices, because what I like, may not be what you like..its a matter of personal preference. But in this particular case, I'd go for Panasonic. Why? Better features, better service, easier availability of parts, and better resolution.Plus some nice features. If this answers your question, PLEASE don't forget to rate as fixed. I'd really appreciate it. Enjoy your new tube!!!
