Question about Samsung HCJ552W 55" Rear Projection Television

TV not responding to remote

TV stopped responding to remote. I can turn on manually and adjust but there is no external switch for digital function, only on remote. TV responded intermittenly to remote before it stopped responding completely. I have the original remote and a universal. I have tryed both and am pretty sure it is the TV. I have looked for the IR circuit and sensor but am not skilled in this field. I have a service manual and am an X-aerospace assembler. Is there a circuit I can manually switch to enable the digital function so I can watch HD again? Or is this a pretty easy fix to the IR input circuit?

    My Toshiba 50H81 also stopped responding to remotes, Tried several remotes and none worked so I believe is the IR sensor circuit. Removed the front cover and read two p/n's on the PC Bd. On the green side got 23546754 on the tan side (component side) have 23537944. Searched for both modules, which I think should not be expensive, and could not find any, Please help.

The power button that lights up on the front of the set is also the IR receiver. Clean the little center spot on the power button. This fixed the problem. It gets dirty from pressing the button with dirty fingers, got kids.

The remote control could be bad and the most likly trouble maker. If you can't get the universal remote to at least turn on and off the set, then most likly you have problem in the remote sensor circuit, all the way up to the microprocessor IC. The proper way to trouble shoot this circuit would be to connect up an isolation transformer to the A/C plug on the TV set, and then get a ocilliscope, and start to trace the remote sensor data output from the sensor. If the signal looks distorted or very low or is not present at the remote sensor data output, check the b+ going to the remote sensor. Most of time it is 5 volts. Some sets a little higher. If the data signal is present and looks strong, trace the signal along the Printed circit board. Thru all the jumpers ,capacitors, ect., up to the input to the microprocessor. If the signals good all the way to the processor ,sorry to say the IC is bad. If it turns out you need a remote try 1-800-remotes or http://www.remotes.com Good Luck

I think what you are describing is a form of line paring which is caused by a defective IC in the video circuit those inputs are feeding. Post a email link ad I will send a pic of a screen that has this problem and you can let me know if thats what your experiencing.

SOURCE: Samsung DLP tv w/ black picture will not power off.

If you are not able to bring up the TV's onscreen menu as well, it appears you have a problem with the TV's mainboard.  You didn't mention if the TV had any blinking error codes so if there aren't any lights flashing on the front, are there any on the sides or back to indicate the problem?  Not all TV's present error codes, but since the TV is maintaining power, it's worth a shot to look.  You could try a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power button.  Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
If this still doesn't resolve the issue, service would be required so you would want to contact Samsung regardless of your warrant standing for service options.

After reviewing the service manual for this set, the problem is is in the DIGITAL BOARD. To get the right Digital Board you will need the Version number of the TV.

Good luck

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Cant get cable tv


Hello
First connect the cable to its cable input socket at rear.
Turn the tV On and enter its Menu option window. Press UP or DN button on the remote control to select 'Cable'. Selecte EZ scan [channel search]. The TV must scan for all available channels, and will stop after all the channels has been stored in its memory. You have to wait till the search function stops; no other functions with remote cannot be done, and the set will not respond any external command, either by remote control or by its front panel control, except the mains power ON/OFF switch will work. OK.

What must i do to start programming my remote to my tv


First look up your TV code in the manual (link below). Some TVs are manufactured by another company, so you can try codes for the manufacturer's TVs as well. Funai makes a number of brands (including Emerson); your TV manual may indicate the manufacturer.

Then turn on your TV, if possible. Then press and hold Set (just below the LED) until the LED blinks twice. Enter a four-digit code with less than 10 seconds between key presses. Press the Power button and check if the tv turns off (or on). If the TV does not respond, try a different code. When the TV responds, check if the other functions of the remote work.

One For All remote manuals and code lists are available here: http://www.oneforall.com/support/manual . Use the drop down menus to select Universal Remote and then the model. You may need to change the Region at the top of the page.

The direct link to the URC-1050 manual is: http://www.oneforall.com/uploads/support/71565305a95bc645c30a7af2b6994b71.pdf .

Please note that the manual for this remote has a copywrite date of 2002. Most universal remotes are limited to codes for devices released 6 months or more before the remote was programmed. If your TV is newer than your remote, you may need a new remote.

I hope this helps.

I need a code for a memorex dvd


Your code is not listed on the manual . Try searching for the code. Here is how: (P.S. if the search function does not work you may have to try a different brand of universal remote.) SEARCHING FOR YOUR CODE If your device does not respond to the remote control after trying all codes listed for your brand, or if your brand is not listed at all, try searching for your code. NOTE: Before performing a code search for a DVD player or a VCR, turn on the device and insert the required media. For example, to search for a code for your TV: 1. On the remote control, press TV once. 2. Press and hold SET until the LED (red light) blinks twice, then release SET. 3. Enter 9 - 9 - 1.The LED will blink twice. 4. Aim the remote control at the TV and slowly alternate between pressing POWER and TV. Stop when the TV turns off (after pressing POWER). If the device does not have a Power key, you can substitute another function, such as digits 0 ~ 9 , CH, or PLAY). NOTE: In the search mode, the remote control will send IR codes from its library to the selected device, starting with the most popular code first. 5. To lock in the code, press and release SET.The LED will blink twice. 6. To search for the codes of your other devices, repeat steps 1 through 5, but substitute the appropriate device key for the device you are searching for. here is the manual for your remote:

I need a 5 digit code for a Craig 13'' TV model DXAI8580-3 for my Directv remote.

If that does not work try this:

1. Turn on the TV.
2. Slide the MODE switch to TV.
3. Press and hold the MUTE and SELECT keys at the same time until the green light under the selected switch position flashes twice, then release both keys.
4. Enter 9-9-1 followed by one of the following four digits:

Stereo Receiver/Stereo Amplifier - 3
5. Press PWR, or other functions (e.g. PLAY for VCR) you want to use.
6. Point the remote at the TV and press CHAN+. Repeatedly press CHAN+ until the TV turns off.

7. Use the CHAN- key to step back a code.
8. When the TV turns off, stop pressing the CHAN+ key. Then, press and release the SELECT key.
NOTE: If the light flashes 3 times before the TV responds, you've cycled through all codes and the code you need is not available. You must use the remote that came with your TV.
