Thanks for the 1k resistor tip had one today stuck in standby, fitted the 1k  resistor to the invertor chip and it came up nicely ! One to remember

Just love those Vestel IPS -they're all triffic. Had a problem where backlight cut, got a new spare board from Daz then discovered the tubes suspect from cold so did the 1K duff tube sensing mod. In my case set didn't cut to s/by but if you want a nice newish 17IPS02-2 I have one.

All the best - Chris.

Hello,can  you  explain what is   1K duff tube sensing mod?

Thank you

no need  to answer,I found  it

"Hi mrfriss
The 1k resistor mod is a possible cure for a lazy ccfl backlight tube. If this was your problem you would have the symptom of sound ok but no backlight illumination. Switching the set in and out of standby would not be an issue.
Seem to recall that the documentation about the standby switching voltage was incorrect in some way but can't remember the exact details.
Think your set is exhibiting a fault different to mine because it appears that you are able to bring it out of standby. From the description it sounds like a corrupted eeprom IC stuck in some sort of test mode. Try holding the menu button on the remote control for a few seconds while the screen is flashing. Sometimes it can act as a reset.
Checked on the circuit for c536. Assuming the numbers are the same on this version c536 also decouples the standby 3.3 volt line - just a bit further downstream. So upgrading it would have the same effect as either of the capacitor mods you have tried.

John. "

Thanks  anyway
