Is there a repair manual for insignia NS-LT-DVD-26?


Service manuals are hard to find now a days, even service parts. Check the link provided to find the main board for your LCD.
Finding the tuner alone might be hard or if you do, it might cost you the same as replacing the entire main board.

Instrument cluster black


If you have the 3-Panel Digital Cluster, with the Fuel on the Left.., Speed in Center.., and Odometer on the Right.., and the Cluster is going Wacky.., works one minute then craps out the next.., take the dash apart and remove the Digital Cluster. Take your time when unplugging the harness behind the cluster, use a mirror if you have to.., to unplug it correctly.

The problem with this Digital Display is the Solder Connections.., at the 14-Pin IC Chip.., which is directly behind the Odometer Display on the main Circuit Board. When you get the Cluster removed.., again.., take your time.., and take the cluster apart.., so you get the main circuit board out. The 14-Pin Integrated Circuit (IC) Chip is marked with an IC2 on the main board.., which as mentioned is behind the Odometer Display. The IC Chip is usually Black in Color.., and is '@' 1/4" x 3/4" You will need a Soldering Iron.., @ a 30 watt with a pointed tip.., don't use a Soldering 'Gun'., too hard to use and too hot.., you don't want to cause yourself more problems by messing up the board circuit tracks by overheating them.., so it's best to use a smaller iron. It is a good idea to have some fine strand solder on hand.., but you should not need it.., all you want to do.., is to 'Re-Tin'.., or 'briefly' melt the Solder at all 14-pins of the IC Chip.., on the back side of the board.., to Re-Flow or Re-Solder the Connections of that 14-Pin IC Chip to the Circuit Board. That's all it is..!!!

I just repaired my 1991 Olds Cutlass Supreme 3.1.., 3-Panel Digital Instrument Cluster in this manner.., and it has been "Perfect" for a month now..!!

Take your time.., get it all back together.., and my bet is that it will be good to go for many more years to come..!!

Good Luck.

I replace the convergence chips and all the resistors,and still got the warped picture,What i need to do now ,please help.Tanks


You did not supply a model number so can't narrow this down further. However it could be several things which may be:

1) The STK chips you used were defective.
2) When removing the original STK chips you also removed a surface mount resistor in the area
3) You have a fuse blown either on that board you did the work on or a power board
4) Check for good solder joints and make sure you didn't short out any pins to an adjacenent pin.

If I was to guess, I would say in order I would expect it to be item 3 above first, then 4, then 1 then 2.

Pmp3000 got hit by lightning 1 leg of the ic2


Th TOP221P chip is available but I can almost guarantee you have other damage as well. I assume it is pin 5 that burned. D7 and C16 would certainly be destroyed. IF IT IS ANY OTHER pin, you will find many other parts destroyed. D7 is a common 1N4007 and C16 is 4.7mfd/450VDC. Remember to carve out any burned baord material as it is conductive.

For the chip you can procure it here:

Dash board keeps blinking on and off


It is not the computer.

If you take the dash apart and remove the digital insturment panel.., use a soldering iron and re-tin.., or heat the solder connections on the back of the circuit board.., just enough to briefly melt the solder.., to re-establish good electrical connections. You specifically want to pay attention to the IC Chip on the circuit board.., which is a 14 pin IC chip that is Black in color.., and measures about 5/16" x 3/4" usually labelled IC2 on the printed circuit board. You can start with this component and re-try connecting to the harness in the dash to see if it works.., if it works.., great.., if not.., just go ahead and re-tin all of the solder connections on the back of the circuit board. The 14-Pin IC Chip is usually the main source of the problems with this digital dash panel.

No picture


Had the same problem, Insignia 32 would click on then go off. About 6 months ago I found (somewhere on the net) a guy who explained that he changed blown capacitors. As I recall he even posted a picture. I found the blown capacitors and replaced them with larger capacitors (less than $20) problem solved...
But now my screen image is showing only half a picture and is pulsing on a off.

Norcent not working


We have ten LT-2722 with similar power problems, at beginin the monitor turn on and off after few minutes or hours, then no turns on at all. But the problem is not at the Power Board, is a bad contact or damage in a integrated circuit U403 (GM1501-BD) at the Main Board, unfortunatelly this IC´s pins are unaccessibles so you must replace the all Main Board (Part Number CBPFF84KMGNCT)
Good Luck.
