Problem with green tv would not turn on

Thanks fo the help! Now my question is- I found the ics stk392-040 but I also found a replacement board that the ics and heatsink is located on. It is called a sub delf board part #aa95-00705a, now will that come with ics allready installed on it? And will that fix the convergence problem and allow the tv to turn back on?

The tv will flash a green light and will turn off, it doesnt turn on either when you power it on


if the green light is a flash on screen with retrace lines most likely the video driver ic on the green crt board , just take the speaker grill .
theair should be a way to get to crts. the one in the center is the green crt. the green video driver ic is an inline 24 pin ic.
to test unplug the video drive plug leading to green crt board turn tv on .if it comes up its a bad ic.
if not unplug the crt socket ,and try to turn it on if it comes up
bad crt internal short hope this helps, butler

palmer_band,

Due to the fact that you recently replaced the convergence ICs I would look at that area. Check all the resistors, diodes and semis for any problems. If none are found use my tip at http://www.fixya.com/support/r6396176-projection_tv_troubleshooting to help troubleshoot your unit.

Thanks for using FixYa and for the great rating.

My LG HD tv screen suddenly went green. sound is


Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

I have a panasonic PT-47wxc43 projection tv. I have green and purple halos coming up from the bottom. The screen has purple and green double images which are worse from the bottom up.


Hi,
This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

LG plasma have an amber light when turning on then green then red


After all the research I found out that the IC on the Z board is bad and new board was ordered and replaced. The plasma work fine after that and picture is excellent with the new board. This forum is great, without this I couldn't fix it myself. Thank you.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.
