This fault is not related with power board replacement. A firmware update is necessary. Contact any service technician, or the authorized service centre for Insignia. Electro help

SOURCE: DOES PLASMA TV HAS 120HZ AUTO MOTION PLUS

This particular model has a 60Hz refresh rate. At this point there are no broadcasts or video sources outside of special labs that can generate enough data to produce a refresh rate of 120Hz. Expect this to become available in a year or so. Please realize that the human eye can not see changes faster than about 30 frames per second. The current standard refresh rate of 60Hz is twice that. The only change you could see (unlikely) would be a slightly smoother flow for fast moving scenes. Typical movement on the screen will not likely see a difference.

SOURCE: replacing power supply main

your best bet is to check owneres manual and keep with what they suggest however when ordering you may want to ask for tech support to see what they say but i would stick with what you had especially if it worked great that way you dont want to overpower your tv if that is what it was used to ..if it ain't broke don't fix it i hope that helps

SOURCE: 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.

SOURCE: avol ALT42FD120 - frame rate change 60-120hz?

Hi. It is entirely possible that the set is already running at 120Hz after all. The display 1080p 60Hz is merely the signal it is receiving and the earlier TV's that used to claim 100Hz/120Hz merely did so using line doubling only to give a clearer picture by filling in the blanks between scanlines. If your picture is already very clear, then I wouldn't worry about it

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.

I have a Insignia NS-L32Q-10A that will not power on. Now power on light or standby. I have replaced the power supply already. All caps look good and fuses check OK. What next???


ok, when you plug in the set, does the power light come on? Assuming you ordered a power supply in good working order, you may very well have a faulty main board. The power supply produces standby power that the main board uses to power the standby/power on light. Your main board also uses the standby power to provide the "ON" signal to turn on the rest of the power supply.

Have paint spraygun 60hz. want to use it in 50hz area. what can i do


Unfortunately, products are designed to work with specific voltages and frequencies. Some devices have broader ranges of voltages and frequencies because they use electronic power suppies (often called "switching power supplies") as opposed to the costlier, heavier transformer types. Nearly all devices that have motors or have a transformer will be designed to operate on either 50 or 60 hertz - not both. Use of these devices with a frequency other than what it is designed for will run too fast / too slow and will overheat to the point that it may become a fire hazard. Unlike voltages that can be easily stepped up or down with a transformer, there is no easy, inexpensive way to change frequency.

You should replace your "60Hz only" equipment with 50Hz or 50/60Hz equipment, or if a short term relocation, rent the correct 50Hz equipment instead.

I hope this helps & good luck!

Insignia quit working after storm


Check the fuses on the power supply board first. They usually blow when you get a power surge. You may be able to replace them and get the TV running for a few dollars. If the fuses are good then the power supply board will be the issue. The main board should not be damaged because the surge has to go through the power supply board first.

Insignia 24E730A12 Won't turn on


let the power supply discharge..for an hours..


Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

A 37 inch insignia tv won't turn on after i plug my laptop for some music.then after unplugging my laptop it won't turn on.please give me best possible answer.( tv is about 2 years old)


This is the basic guide that can be applied to most LCD flat panel TV.

First, try unplugging it from the outlet for about an hour to see if the TV will reset itself since the minute the TV is plugged into the wall, the power supply and processor will be running 24/7 and the EPROM can get corrupted by spikes and surges. Try using good quality surge suppressor to see if it will help if it happen often.
Look for burnt brown hot spots on the circuit boards, capacitors with leaking/bulging top or seals. Loose wires and connectors. Blown fuses.
Notes: We are dealing with high voltage that can kill you! so if you are not sure what you are doing, please have it fixed by the pro that has proper tools and safety equipment. Try to use GFI outlet and isolation transformer when work around the TV set and DO NOT DEFEAT THE GROUND PIN OF THE OUTLET/POWER CORD.

1)The power supply module (There are 4 regulated output voltages:- Standby 5vdc, switched 5vdc, 12~16vdc, and 24vdc).

The power supply converts the 120/230vac 50/60Hz into DC, then the high frequency (50~100kHz) switching circuits convert it back to AC but at high frequency which allows the power supply to use smaller and much lighter weight transformers (Ferrite core instead of heavy iron core), then this high frequency AC voltage is fed to the rectifier Diodes to get the DC output and filtered by DC filter capacitors that must have low ESR (Equivalent Series Resistance), if general purpose electrolytic caps are use, they will fail within a year or less due to high ESR.

The power supply has Standby 5vdc (5VSB, this is a MUST have before anything else will work, when this voltage is not present, there will be no any indicator light on the front panel) which is always on the minute the TV is plugged into the AC outlet, so it is on 24/7 and that is why the power supply will fail even though you may use the a TV not very often. It will see all the voltage spikes and surges 24/7.
This 5vdc is used to power the Processor and the Infrared remote receiver module which will be waiting for the command from the remote control or from the power switch, when the Power on command is received, the Processor will send the turn on signal (3.3~5vdc) to the power supply module (PSON pin) to the switch on the main 5vdc for the rest of the logic and Tuner circuits, 12~16vdc for the sound amplifiers (mostly Class D amplifier for efficiency and small size) and for the T-CON board (interface board between the LCD panel and the Logic board), and 24vdc for the Back lights inverter board (if there is no 24vdc then no back light).
Common failures:
Blown main AC fuse due to shorted out Diodes, transistors.
Bad capacitors leaking or bulging tops:
Shorted Diodes, transistors in the DC output side.

Most common problems in the power supply board are dying to be dead capacitors.Check all those dying capactors,for bulges up on it tops or puffing up on it tops.Replacing these capacitors,95% ur tv will,get power back and work.
