Lots of good information here.DeleteNeoxyNovember 1, 2013 at 7:04 PMUf. I've got a lg tv 26 inch 26LB75-ZE. Metal shield Unplug these cables When you are finished with CCFL cables, unscrew the LCD module and carefully unplug LVDS cable from the module.

Whenever I turn on my pc, the monitor turns on but no display, the screen changes colors from pure black to white, red, green gray. And now for the triple whammy: when I wave the pointer across the lower part of the screen, you see normal pointer travel. The chopper transistor and PSU transformer were getting quite hot D920 (PSU secondary HT rectifier) was s/c. You can take the LCD module appart and try applying some preasure to flex cables and see if other part of screen appears. official site
This is a TFT panel fault (probably one of the flex cables connection that go from TFT driver to TFT panel is bad)you will have to replace the whole module. SMPS Faulty capacitor here is visible Next use your multimeter and measure the resistence of high voltage side of the inverter. this could also be the case because of interference from high voltage source.
Sry for the late response. It only blocks the blue led light underneath for about 30 minutes before it shows the desktop, now for two days it doesn't show the desktop at all only blinking. this link is very helpful...ReplyDeleteAnonymousJune 7, 2013 at 8:43 AMHi there I have samsung syncmaster 633nw. Do you have any troubleshooting tips to share?
I can read text on it but its annoying watching videos. All capacitors from them look good. Use 10M Resistor on insulated crocodile clips and place on capacitor terminals. http://www.pcadvisor.co.uk/forum/helproom-1/lcd-monitors-advice-99142/ DeleteJuan PabloJanuary 4, 2014 at 4:58 AMOk, thks!DeleteReplyNeoxyDecember 11, 2013 at 3:16 AMThis comment has been removed by the author.ReplyDeleteUnknownDecember 20, 2013 at 8:58 PMHello.

Every time I run into any electronic device that has some bad electrolyte capacitors I make it a point to replace all electrolytic caps. click here now Besides replacing them there are 2 keynotes about the replacement (based on my experience). You can read about this here: http://www.febalcdrepair.com/?title=tcp_tab_bonding&menuid=13I repaired one monitor with this symptom and what I did was, that I stuffed a rubber piece between a LCD module frame and panel SMPS filter capacitor does not discharge at all Suspect the flyback transformer (K.
I tried this with Lenovo and Acer monitors and both are working fine by just replacing the thermistor. have a peek at these guys This is dangerous and a fire hazard. CRT Trinitron ...or TFT... Is there a way to find the schematics of the boards or the expected values of different points i can test?
From my experience, the main faults are:- 85% faulty capacitors- 10% faulty inverters- 5% other issues (faulty buttons, main board, LCD module, CCFL, FETs) Fixing this problems is very easy Conclusion, fuses suffer from metal fatigue and fail without a serious fault being present. Q001 was also faulty (F630), replaced with IRF630 this cured the fault (Leon Guthrie, electronics tech - Borders college. check over here I'm >not sure what to look for in the newer slimmer monitors.>All advice appreciated.>John Slevin. >By flat screen do you mean the TFT flat panels??

It was always the weak spot for such faults.
we can fix vertically/horizontally lines on LCD and many other issues. And why should you? Only one of top or bottom will be burned out. Or there is a weak connection in VGA cable.
Visible arc burn present. Then I'm afraid there is something wrong with the main board or the LCD panel. I like the Sony TFT monitor- but I found this about them.click here Rayuk 19:04 20 Jul 03 A little more info on dead pixelsclick here Djohn 19:04 20 http://neoppidum.com/advice-on/advice.php Sound works perfect.
Makes you wonder what the "fail rate" is on Sony Viao flat screen doesn't it.Thanks again. If you find them replace them too.

But I agree, if the LCD is in your own possetion you can open it and change capacitors when they die again... we are up and running. If it is the problem is in LCD panel or connection to it. You can get capacitors and buttons in your local electronics store.
I replaced the thermistor and its working fine. It was in warranty, so they took it back and fixed it. I also recomend that you replace all capacitors on voltage lines on SMPS even if they appear to be good. This thread is now locked and can not be replied to.
Replacing with a BA159 cured the fault (Simon) Belinea Monitor Model: 10 20 10 Dead, power LED flashing and ticking noise Q422 (2SC5297) Line Output Transistor was dead short.
