Sceptre X9G-NagaV I need to know the value of R88 in order to replace it, and is there a list of components for the parts on the power supply board

replace the power supply

May i know the exact detailed model/maker of your unit...?

Hello,

You have a power supply that is about to die. If you can solder you should be able to repair the monitor yourself. The problem is caused by blown capacitors on the power board. Go to our web site at : www.ccl-la.com/badcaps.htm We have pictures of what to look for. Open your monitor and look at the power supply board for any blown capacitors, replace all that you find. The replacement parts can be ordered from several places on the internet or we can supply them for you. The replacement parts will need to be high temp and will be marked 105c. The values you need to get will be marked on the sides of the ones you take out but will be something like 220uf, 470uf, or 1000uf etc. and then a voltage rating. When you install the new ones be sure to insert them with the polarity stripe going the same direction as the old ones come out. If you don't want to do the repair yourself we do offer a repair service for $35 plus return shipping. If you have any questions just let us know

I hope this helps if so please rate our solution.

I would suspect the capacitors on the power supply board. Other sites show that power up problems are due to the aluminum electrolytic capacitors on the power supply board being defective. Replacing the four 470uf 25v capacitors (470 micro farad, 25 volt) on the board usually fixes the problem. Sometimes also the two 1200uf 25v capacitors could be the culprit. I suggest changing them all. The price is about $7 for the parts online at Mouser electronics plus $7 shipping. I just fixed mine. I bought two 1200uf 35v capacitors, Mouser part number: 647-UPJ1V122MHD6 and four 470uf 25v capacitors Mouser part number: 661-EKY250ELL471MH2 These are slightly larger than the originals but still fit and they were in stock. You will then have to open the unit (relatively easy) remove the power supply board by removing four screws and disconnecting the connectors (Make a note of wire colors and where the connectors came from before removing). Then you will need to remove the old parts by desoldering them and then solder in the new parts (somewhat easy if you have soldered before)

This board is out of my Sceptre X9G Komodo. The 740uf capacitors are clearly marked 25V. The 1200uf Caps are 10V. I ordered parts for mine to try. The darker 740 has a slightly "popped" top.
470 is about 10mm dia X 16-17mm long
1200 is about 10mm dia X 20? long
two leads on each about 5mm apart. They are soldered to the board.

My Sceptre Komodo 19 would turn on for less than a second than turn off. Eventually, I could get it to stay up. But after a month, I couldn't get it to stay on anymore.
I found the solution on this website. There are some bad capacitors... 4 of them for about $2 worth. I replaced all four and the monitor works fine again. They are soldered in. They are polarized; they need to be installed the right way. The white stripe goes towards the “wall”.
2 are 470uf 25v and 2 are 1200uf 10v.
I ordered mine for about $10 with shipping from Mouser.com
661-EKZE250ETD471MJ1 and 647-UHE1A122MPD

1000uf 16 VOLT

check out any dry solder or burnt and re solder it , hope it helps AJ

Go to ebay, type X9g kimidi logic board. Usually, some seller might have pulled working parts from other monitors and sell them individually. If you cannot find them, google "buy x9g komodo logic board". Some website, I'm quite sure will sell them.

I recently came accross one of these monitors (Planar PE191M) with the identical issue. The resolution was to replace the two 470ufd 25V capacitors that are located on the main power board. The main power board also contains the audio circuit and more importantly the inverter circuit that drives the CCFL backlighting. The suspect caps were identified using an ESR meter; if you happen to have one of these meters you can confirm this is the issue with your unit(s), alternatively you can just replace the two capacitors and see if it resolves your issue. Hope this info helps someone out there.
