    After a while, the picture just goes - even though there is still sound. Strangely, if I switch off at the mains, rather than the tv itself, the picture usually returns (for a while!).

    This Pentus piece of **** is just over 2 years old. I bought from Currys in Liverpool. Never again. Pentus or Currys.

    I'm told that even a diagnosis would be costly. I think I'll just take it to the tip - and read books instead!

SOURCE: philips 50pp9202, no picture but sound is fine.

I have the 51 inch of this model and I have found that usually it give you some indication before going completely out. Like color problems, sound, or just video disappearing. Most of the time it will be the convergence amps going bad, but you should have seen some color distortion. If not then it could be the vertical output. TDA8177 needs replacing and check caps around and diode, If not this then look for open fuse in HV line to crt's. Also power supply fuse like 1900, 2004, 1300, etc.

Same problem with Channel 71 CBeebies. Tried rescanning which worked initially for a few weeks but it's back and rescanning does not fix the problem now.

SOURCE: i have a Samsung LE26R72B.

Solution that worked for me:

Enter the service menu:
1 - turn of tv with remote
2 - press and release in the following order on the remote: Info, Menu, Mute. Make sure remote is pointing at the tv
3 - turn on the tv from the remote
4 - you will see the service menu. using the down arrow on the remote select the Reset option. Using the right arrow button at this point will do a hard reset.
5 - Wait a few seconds, turn TV on
6 - you will have to rescan analogue and digital channel but it should be working now.

If this Tv is a model year 1996 or 1998, It is quite possible your vertical IC needs resoldered. It is located on the small signal board. This board [quite large anyway] is the board on the left. I don't know the location off hand. The IC has seven pins and located on a heatsink, It is a TDA series. Resolder any and all grounds you see. May as well get the Large Signal board [On the right] resoldered. The other problem would be the P I P board, a small board standing up, that can be removed and replaced. But try the earlier first. This is tedious, but will produce results.

Digital tv tuner not displaying picture


. Try putting you tv set to channel 3 or 4. Try your tv in all modes. Check the back also to see if in the right spots with the wires. Check your channel scan status, try it on anntena and try it on cable, run channel scan on both. good luck. Try vcr wires if cable wires dont work. vcr wires are yellow red and white. Try another cable cord sometimes they get old. Try looking at your remote and setting it to tv.
