Philips 26PF5520D/10 TV Now, after 2 perfect years,when switching on, the picture is fragmented into narrow horizontal bands which flicker up and down for occasionally only 8 minutes, but mostly 20 - 30 minutes before settling suddenly to clear picture. Clear non-geek advice appreciated. Nick

This sounds more like a connection problem IF you can solder, try looking for any solder connections that appear grainy or have rings and resolder them. It is possible that there is a heat sensitive component as well, but lets start with the simple stuff first.

Keep us posted on your progress.

Horizontal problem


Hi
The narrow picture is often related with a dried reservoir capacitor, the big capacitor placed in power supply section. You can test connecting in parallel a good capacitor with the same capacitance and working voltage (generally 400VDC). You shoul take all precautions required on working with high voltage such as discharging capacitors before dessoldering anything from the board, not touching the "hot" parts, etc.

Picture flickers for 5-10 minutes then goes black


in the back of the t.v. there is a mother board. on the mother board ( im not sure what it is called so i will describe it)
it looks like a black tune. it has a red wire comeing out of he top going to the front of the t.v. connecting to the picture tubes. now see what happens is that tube will heat up and sometimes loose connection. what i found to be helpful is to stick a peice of cardnpard under it so it gets a good connection again. but do becarful because it is high voltage....... so if you decide to try to work on the t.v. please unplug it first.

For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,etc..it's can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

Hi.

If the picture & sound are ok in analogue mode then chances are you have problem with digital tuner.
This may be expensive to repair so I would advise connect external freeview box or sky etc to get digi channels using scart to connect to your TV.

Tube TV - one thin horizontal line of bright light


Vertical defection failure. Common failure. Pretty easy to repair ($50-75?). However, my general rule of thumb is not to waste any more money on TVs over 10 years old. Too much other stuff in there ready to fail as well.
