Question about Sylvania CL772 17" Flat Panel LCD Monitor

Open Question

CL772b Model 780 Sylvania Monitor

In the top left corner of the screen is the following:

HD772 L6502
HTCH TX43D

The only way I can get it to go away is when I press the Menu button on the side of the monitor.

How can I get this to not show up at all?

Thanks!

SOURCE: Sylvania CL772B LCD monitor has no power

The board with 200-100-SH700 on it may be the problem. I came up empty trying to find anything with that number, there should be some other number either ink-stamped on the board or on a paper sticker.
Google can be your friend if you find the right number.
Somewhere there may be someone with one of the same with a broken screen. Ebay?

Testimonial: "I'll watch for a broken one on eBay as you suggested, but it'll probably end up getting recycled. It's not worth putting any money into it. Thanks."

SOURCE: cl772b sylvania (model 780) go to white

You get white screen glow when the T-CON board on the LCD panel does not receive the +5dvc feeding it or it has blown fuse on the T-CON board, see picture of the T-CON board and the fuse here:

Look at the logic board to see if the ribbon cable may have come off the LCD panel or the logic board, also look to see if you can see any bad caps (leaking/bulging top).

Unable to unlock Nuvi 780 screen. The slideing button on the top left dosen't work, it lost the grip and just move on either direction with out any action. Please help


Try to remove the battery and re insert it back in to see if it will work. Or hold down the power on/off for about 15 seconds, that should do the job.


If that does not do it, then you have to calibrate the screen. To calibrate the screen, follow the steps below:
  1. Turn off your nuvi,
  2. Press your finger on the upper left corner of the touch screen,
  3. While holding your finger on the touch screen, turn on the nuvi.
  4. Continue to hold your finger on the screen for about 30 seconds until the calibration screen appears(white screen with touch dot),
  5. Then follow the on screen instructions.
That should do the job for you. hope this helps.

Blue numbers on screen in the upper left. reset only helps for 5 sec.


The text reading on the screen is 772S L7025 AU M1 70ES05 and are always present over applications? If restoring factory defaults, changing resolution does not help then the monitor will need to be repaired, sorry.

Sylvania 780 wont stay on for more than 10 seconds than I have to press the on button again and it goes off after 10 secons again.


If you are going to DIY repair, please read below and look at the pictures in my albums.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I have a sylvania monitor model CL772B. The light is green and flashing after a power outage. The manual doesmnot describe this condition. There is no screen image. How can I correct the problem? If needed...


This seems to be issue with the Computer not the monitor. Check the monitor with different computer or you can check the monitor also. For this take out the monitor cable from the tower and turn on the monitor alone, if you get any message on the monitor screen it means that monitor is fine. Try this and let me know.
