Tyris Model: F179
No Power
Purchased an AsIs non-Working Tyris F179 from Goodwill for $15. Opened the case, found no swollen capacitors. Tested the capacitors on the power board and found C203 680uf 16v and C202 680uf 16v only partly working. Could not find a pair of 680uf caps and since they were in paralell on the same traces I removed both of them and substituted with a single 1500uf 16v capacitor. Next, the video board does have a Novatek chip much like the Novatek chip in the Samsung 710n but look closely at the 5 and 6 legs, they are not being used in the Tyris design so the 5/6 50ohm resistor fix is not needed here. Did find C107 , C16, C50 weak, all 47uf 16v, so i replaced them. Reassembled and now have a great picture again.

i'm not an expert at anything...x'cept maybe dumpster diving. God Bless

Sounds like a bad inverter or CCFT(s). Adjust the brightness to the darkest setting. If the display stays on longer, the you have a bad CCFT(s). If it still goes out the suspect a bad inverter.

What should the tyre pressures be on a vw sharan vr6, 225/45/r17?


Tyre pressure is given by the manufacturers for both ride comfort and wear. For comfort, most are recommending 32 PSI, I personally have found with the lower profile sport tires, that running 35PSI gives the best ride and tyre wear.

Screeen comes on --then goes blank


Your inverter circuit is faulty. This controls the lights inside the screen so you can see what is happening on the LCD panel itself.
If you shine a torch into the LCD from the top at an angle you will still see the images on the screen. But with no light inside to project it outwards, it's dark.

A local TV repair shop should be able to do the reprair fairly cheap, but it's best to make a few phone calls and check they will work on an LCD monitor firstly, and secondly a rough quote.
This is a very common fault with LCD monitors.

Hope that helps =)

Monitor is blank/black


It is probably the inverter board inside the monitor.
(if the screen does properly display ever then it is not the screen)
It CAN be fixed but I do not suggest anyone open up a monitor (LCD or CRT)
who is not "technically inclined." If you really want to fix this
particular one then take it to a local tech and get an estimate first. If it's almost as much as a new monitor then buy a new one.

Screen goes blank after 2 seconds!


Blank Blank or can you see shadows?
If you see shadow images then the backlight or inverter has failed
If it is blank blank then graphics card or connector/cable problem
Does that help
