The Ohms are ok but the wattage should have been the same or higher.A 1.5 with only 5 watts is not sufficient.

Chassis is completely dead


Hi,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

The tv will not power up, I pluged it into an outlet by itself and nothing. Could it be a fuse?

Hi kfulcher247,

4.If you see that the fuse is intact on the board, don't attempt to touch anything because there somefatal components stored electricity enough to hurt you with a simple mistake only.

The next steps should be done by an expert or qualified technician because isolating the problem on the power supply is quite technical.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Panasonic TV model CT 27D10B fried by lightning surge. Where to start looking?


Hi There,

I am unsure as to "where to start looking" means? Do you mean parts to fix it or new TV's?

If you are looking to fix it, you will end up spending a lot more than you prolly want. The surge could have blown a board, Power Supply, fuse, capacitor, transformer or a combination of them all. These TV's are only 27" and if you look on government websites you will see they start the bidding around $5 for the whole TV. If you are looking to upgrade I would suggest balancing a budget that works for you especially with the economic issues going on. 1080p is the latest being talked about, but that doesn't mean it will work for you. I went to Walmart and spend $600 on a Visio HDTV 1080i and I have not had a problem yet (knock on wood). I would not suggest buying a Panasonic HDTV but that is my personal opinion - the majority of issues I have resolved at my full time job came from Panasonic Projection TV's and HDTV. At the same time they were able to shoot out one of first 103" TV's but that just means some tech will have a bigger TV to fix in the future - LOL..

Hope this helps and feel free to rate me..

Happy Holidays..

CT-27SX11E Fixed but need advice on R value


I have already responded to your first question in relation to the Ohms and wattage,It worries me that maybe you can not see an answer to that question.The wattage rating should be the same or highier.

CT-27SX11E Fixed but need advice on R value


i would not recomend replacing the 7w with the 5w, beacuse the resistor will allways run hot, hotter then the resistor should be. the resistor could possible melt anything that touches it & will not last as long as the original before it goes bad. find a 7w, if just for safty reasons.
