    My same tv shut intself off, will not turn back on, green llight flashes. When someone has found a solutiion, and/or had it fixed, I would appreciate the details, including who fixed and cost. I called BB and they said that I could being it in and pay for shipping to and from Insignia, they were unable to provide cost. My fear is that with shipping and repair, that it would be too costly, and maybe throwing good money after bad. Thanks, M

    yes I have the same problem. Went to turn the tv on and had not power, with the same ticking sound. I took it to a local electronics repair and they said it was the power supply, but they were unable to get the part to fix it. So I did some calling but so far am unable to get the part from Insignia. They directed me to a national part supply for best buy but they did not have that part. So far I am out of luck. I wonder is there is a power supply from a different company that would work with this tv?

    Same problem. Two year old IS-TVHD30 clicking sound, flashing green light, electrical smell. This is the LAST Insignia product I will ever purchase. TVs like this shouldn't be failing like this. Called Insignia, but sent me to Best Buy. Best Buy says that they'll charge $100 for diagnostics, $170 for T/S, and then the cost of parts. This comes close to what we paid for this piece of ...

    I have the same problem with my Insiginia TVHD30 model. It does not turn off. I called BB and repair cost just to come out are in excess of $100. I wrote customer service and the home office and they are not willing to help. Basically they say should have purchased the extended warrenty. I am now trying to find a repair manual in hopes my husband can attempt to repair. It's a shame that a TV that cost me over $400 died this quickly (less than 2 yrs).

Insignia tv-30 inch ---model is-tvhd30 has burned capacitor-c359--need to know the value in mfd's.

If it is in the power supply better check the rest of them. most should all be the same value so you may be able to get the value for the burnt one from that. good luck

Insignia lcd 37''powering off and right back on by itself!

Hi Ed,
Since the TV is less then a year old and still under manufacturers warranty, I would suggest to take back to the vendor to get it fix because this LCD behavior is not going to get any better.
The failure on this TV is related to a power supply in most cases if the TV is turning OFF by itself or needs to be unplug to let cooldown and it works afterward.

I fixed the problem with the "no power on, low clicking noise". The NPN transistor (2SC5931) was shorted. This transistor controls the horizontal hold. The shorting caused the power supply to overload and restart, then recycle. This was the cause of the clicking noise. Unfortunately this transistor was over $50, most likely due to the extinction of CRT's. I did find a replacement transistor 2SC5552, which only cost $2 (but I was able to get it in Mexico). The location of the transistor is located on the left side of the TV (looking from the back). Directly in front of it is the high voltage transformer which powers the CRT (should have a thick red wire). The transistor is attached to a large aluminum heatsink. To remove the transistor you will have to remove the entire electronics assembly to you can easily get to the underside. This was the solution for my TV, but there could be other components damaged.

Prague 49011G, automatic wind watch - stopped ticking

I also have a Prague automatic watch (not the same model) which I purchased in 10/06 and have had it repaired twice. If you purchased the watch new, a little white warranty paper should have accompanied it. If not, you might be out of luck. Anyhow, each Prague has a two year warranty. My warranty instructed me to send the original receipt, a check for $10 (for return shipping) and the watch to Croton Repair; 195 Anderson Avenue; Moonachie, NJ 07074. There of course is no phone number to call them. Make the check out to Croton Repair. The warranty also says they do not guarantee they will fix the watch, but they guarantee they'll send you the watch back if it cannot be repaired. It took about 5 weeks and my watch came back repaired. Unfortunately about 6 months later it broke again, same exact problem (no long self-winds, ticks or keeps time, my watch also has a diamond at each hour, two of which fell out)... I've seen a lot of the issues people are posting seem to be the automatic watches not working. Probably duds, the inner workings seem to be very sensitive.
