Goodmans GML22W29HDVF / Vestel 17mb29 main board

<< < (8/8)

mrfriss:
Another thought... could someone guide me through the menu structure to reset the chip?
I believe my set is fully working, but stuck in a test display sequence.

So after pressing 'menu', '4', '7', '2', '5', how many ups, downs, left rights do I need to do a "INIT NVM"?

What other options do I have in this service menu?

Thanks!

Hi mrfriss
From memory- MENU 4725 should bring up the service display. Scroll down to RESET option. Press right scroll button. You should see another screen that tells you to press the green button. Press green and it should reset the software before switching itself to standby.
Best of Luck
John.

Thank you, but not exactly what I meant...

I need exact button presses to reset the device (or do something else that could get my device out of display test mode).

So if anyone has a device with this main board, please enter the service menu and post the options or take a picture and share it, somewhat like this (including sub menu's): http://www.djsmiley.com/got/pics/techwoodtv/hires/dscf9824.jpg

Frustrating that the set fully works, except displaying the images (sound works and it responds to button presses)

HI again guys. I didn`t have enough time to have look back on these sets but fault is definitely on the PSU board,that`s my opinion. Like I set before, I tried change couple working chips but without change.Few months ago I change all those Big caps,for value at least half more  like they was.One of these sets is working over good few months with no problem at all and customer is fully satisf. Guys, do not put tv into the INIT NVM reset mode .That is only wasting the time.I did this on other two sets before and then I has to reprogram all settings in Service mode.Every f...... step.reset of all factory settings so this is a bad idea for me.My Set is coming on after about 10 seconds when blue light is off,self test or something like that,no idea but then working perfectly. I`ll have the same unit for repair on table this saturday.Caps should have a Value of around 1200 uF per 1 Amp floating current DC.These G-Luxon,Teapo and similar family of 85 °C chineese  piece of shity caps are not suitable for switching power supply. Use real low ESR 105°C selected brands of caps and also check the datasheet.Main board rechecked for bad caps and dry joints by ESR and other eguipment.1000uF replaced by 1500 and other with higher value. Do not exceed too much,double value my cause some fault.Try this ,works for me :34:.Good luck.
