Question about Insignia I-LC23Q1 23 in. HD-Ready LCD Television

2 Answers

Insignia TVHD30 The TV has worked perfectly for a year and a half or so, but a thunderstorm passed the other day, and now it does absolutely nothing......NO lights, NO responses to switches or remote. The TV is plugged into a surge protector strip along with a DVD player, Satellite box, and VCR. Those all appear to be working; at least they have their "ready" lights on. I suspected a fuse, and took the case off the TV and found a line fuse, but it checked good with an ohmeter. There are no burnt smells, and no unsightly capacitors or other components inside. What should I check next? Thanks

Call insignia and tell them that your TV IS-TVHD30 smoked out on them and ask to have it fix. This problem happens a lot they should fix it free of charge.

I have sound and picture distortion (like what happens during a thunderstorm) in my 42 inch insignia lcd tv but not during storms. started about two weeks ago, happens intermittently. driving me nuts. is...

Your probably having what cable guys call a SNR ( signal to noise ) issue. There's no way to know unless you call your cable provider. The SNR should be 32 and above with zero pre/post errors. In case you want to ask the tech what they are.

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

Sounds like power supply problem (either poor connections or bad capacitors).sometimes they look deformed or you have to check them with an incircuit capacitor tester.

No picture

Try a "hard restart". which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent.
You can also visit the manufacturer's website or call their tollfree number for problem solving info.
Hope these suggestions help you out.

IS-TVHD30

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.

Take a look at D517 in the power supply for faulty solder joints. That's a common component problem in these units. Otherwise, if enough transient voltage got by to do any harm you might want to test the following: V504 = 2sa1668 R523 = 56 Ohm 1w N502 = Tlp421 optocoupler IC D509 = 1n4148 If any of this has you scratching your head it's probably shop time... Hope this helps, let me know... Bill
