Samsung TXJ2754 27" TV - Answered Questions & Fixed issues

Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here.

some channels dont work or support closed captioning and only a few vhs tapes support it.

Hello

Your TV displays the closed captions that are broadcast with some

television shows. These captions are usually subtitles for the hearing

impaired or language translations. All VCRs record the closed caption

signal and most pre-recorded commercial video tapes provide closed

captions. Check for the closed caption symbol in your television

schedule and on the tape's packaging: .

1 Press MENU repeatedly until you see the Setup menu. Press CH
to select "Caption."

2 Press VOL+ to open the Closed Caption menu.

3 Press VOL + to turn closed captioning on.

Misspellings and odd characters can occur in captioning. Also, there may be a

captioning delay after changing channels. Neither situation is a TV malfunction.

4 Press CH to highlight "Mode." Press - VOL or VOL + to choose

"Capt." (captions) or "Text." In caption mode, captions appear and

cover a small portion of the picture. In text mode, information unrelated

to the program, such as news reports, are displayed and
often cover a large portion of the screen.

5 If you wish, use CH , CH , or VOL + to change the captioning

channel or field. Then, press DISPLAY to return to normal viewing.

 Different channels and fields display different information, such as additional
languages or supplemental information

This problems the FBT-the Flyback Transformer have cold solders.Must resolders the FBT.The right side wall of the FBT-the "H" horizontal transistor,must be also resolder too.

Check SMPS power supply DC voltages like +12, +5, +24 etc. If you are trouble shooter your self, you can try this with your multi meter.

But one doubt: When you say only horizontal line is visible there should be sound from the selected channels audible!!!!
If circuit is not available note down the IC numbers, track them in Google.
Note down the supply pin nos. You can check the voltages accordingly.

hi! i have here a couple of codes for your tv. just try them 1004, 1005, 1011, 1014, 1018, 1019, 1061, 1072, 1073, 1074, 1097, 1098, 1156, 1161, 1297, 1314, 1323, 1360, 1363, 1364, 1490, 1492, 1510, 1019, 1171, 1172, 1173, 1174, 1175, 1197, 1198, 1199, 1200, 1245, 1246, 1325, 1327, 1352, 1354, 1443, hope this helps! goodluck!

From your description, it sounds like you may have solder joints on the board connecting to the tube that needs simple re-soldering.

Look up your model number of your television on the internet. Look up how to reset the v-chip.

Search for the website of your universal remote manufacturer to see if they list the codes online. Since you did not provide a remote make/model I am unable to search for it for you.

MY SAMSUNG 27# MODEL TXT27820 ONLY NINE MONTHS OLD SHUTS OFF BY ITSELF AND WILL NOT START AGAIN

Sounds like a bad connection on or in the vertical output circuit, or the drive circuit. Could also be the vertical output IC or the surrounding componets going bad. Good Luck

Hi, maybe just maybe something screwed in the yoke. Other than the vertical deflection coil, you may want to try to check the associated components. Sometimes they have diodes connected as a limiter/shunt. Again maybe... Pls post back, curious too. Good luck.

Assuming you have picture on the TV when hooked up to cable, antenna or satellite I would take the DVD player to a friends house to see if it worked on their set (using your cables of course). If you can't get a picture on your TV no matter what, then it could be either the Jungle IC or EEPROM IC inside the set. Since it displays "No Video Signal" on the screen, that leaves out the High Voltage section of the TV. My main suspicion would be the video cable or settings on the DVD or TV.

bro you should take it to the repairer,No other options you have. it can't be fixed by doing anything accept changing it's screen or repairing it, if it's possible

Hello. You can check HDMI cable in this case. If you're using an HDMI port that's not working well or has been damaged, it could result in a darker-than-usual screen. If you switch the cable or change devices and the TV is at a regular brightness, this is the case.

It sounds like you might be dealing with backlight bleeding or an issue with the LED backlighting in your TV. This can sometimes occur over time due to normal wear and tear or manufacturing defects. If it started as a faint single brighter section and has now expanded to four, it's likely a hardware issue. While it may not be an easy fix, contacting the manufacturer's customer support or a professional technician would be a good next step to diagnose and possibly repair the problem. If you'd like, you can share the pictures for a more accurate assessment.

All I can advise is to take it to an authorised Samsung repair shop. A list is available on the Samsung web site.

The old yellow, red, white RCA cables are analogue signals, while HDMI cables only carry data. They are in no way compatible. You can buy active conversion boxes that will convert analog to digital, but simple cables cannot work

It can't be done. The Samsung remote will be single frequency for that Samsung device only and the LG remote for that television (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television. If you have lost a remote or it doesn't work, this is the answer https://www.fixya.com/support/r29872378-universal_remotes_no_facsimile_remote ..

These LEDs are very susceptible to static electricity damage. What happens when they get zapped is a tiny threading fault starts in the LED crystal. The aluminum contact metal starts migrating into the crack, makes it wider and longer, and eventually goes all the way through the LED and shorts it out. When that happens, the metal overheats and burns out the LED so the entire string goes dead. What this means for you is that the original LED may have been may have been zapped at the factory. The replacement strip likewise, or when it was removed from another TV (if it is a used part), or when you put it in. It should have been in anti-static packaging. You have to be very careful not to touch any of the circuitry on the LED strip, and make sure you ground your hand to the TV metal both before picking up the LED strip and right before connecting the strip to the TV. Better yet, use an anti-static wristband connected to the TV frame. It is possible that the LED driver for that string is pushing too much current, but that's not likely. You would probably notice that part of the screen is unnaturally bright.
