Having problems with your Projection Televisions ?

Ws 55511 no blinking light possible lightning run in. checked pico fuses and glass fuse-both ok. I have no continuity across pc9a21. Everything was plugged into a surge protector and nothing that was plugged in there works anymore. Satellite box, dvd player and the tv. Outlet is good. I have the chassis out.



Answers :

Just what kind of component is PC9A21. In other cases, check all grounds on the under neath of both the power supply and the convergence board. You must really inspect for these, grounds in this case are far to common on this TV. The next board to inspect will be the convergence board. I was surprised at how many bad grounds this board will have. The pins connecting the convergence IC to the board are also in need of resoldering! And, most certainly, really eveball the connections that have jumper cables connecting these two boards. This area is terrible for grounds. If one side is bad, you know the connection on the other, is also bad! Before you reinstall these boards,please check you capacitors ESR. You will need to have an ESR meter for this. One bad capacitor can cause a dead TV symptom.This meter may be purchased for about $50.00. This will be a very good investment. You will be able to repair many, many electronic gadgets with one! Thanks for asking and show all hands of support!

I just purchased a Vizio e420vl. When i first plugged it into my surge protector, it worked fine, for about 20 minutes. Then it lost power completely. I went and bought a new surge protector, one made for home theater set-ups, and the same thing happened. When plugged straight into the wall outlet, it works fine. How can i resolve this and still have surge protection?

But red light comes on on TV when plugged in but no response from remote, no picture, no sound, nothing. Checked capacitors and no bulging or leaking from hem. Help please. TV only 14 months old.


The first thing (after unplugging the set) to check is whether you have a shorted diode in the main power section of the power supply. Test each diode with an ohmmeter to verify it conducts in only one direction. I assume from the red light that Stan ... Samsung 52 in. Flat-Panel LCD HDTV

I just got a WS 65807 from a family member who didn't want it anymore. By the time we moved it to our home, it doesn't work at all - no lights, no error blinking, nothing. The only thing I can notice is that when I plug it in, I hear a slight "squeak" so I know that electricity is getting into it but I don't know what to do from there. Any thoughts or should I just go ahead and contact a repair guy? ('cause it's a really nice TV if I can get it working)

I have had a Pioneer Plasma TV Model PDP-4271 HD for about 4 1/2 years and now it does not work. I went to turn on the TV one day and it did not work. There was a faint picture and then the picture cut out. Now there is no screen picture, no sound....nothing. I believe this may have happened when we had a thunderstorm and thinking maybe lightning hit the breaker. I did not have my tv plugged into a surge strip.

My TN61X81 cannot start. When plugs in, there is a "click" sound like relay action, but nothing else happens, screen is black, the front red LED flashes (not in a constant pulse), front "power" button doesn't work. This kind of problem happened before, but it could be solved by re-connecting the power. This time it didn't work anymore!

No picture I replaced the lamp and it worked for 3 months then I lost picture. Pulled it out and saw nothing wrong with it but when I put an ohm meter to the bulb it was an open circuit. I ordered a new one and it lasted 2 hours with the element exploding. Is there something wrong with the TV or are the bulbs junk? They are not from Mitsubishi and the bulbs are not Osram. I have had the TV since 2006 with no other problems. The TV is protected with a Monster surge protector. Any help would be gr

TV has worked just great since purchased in 04. Sat down this morning, grabbed the remote and nothing happened. I replaced the batteries in the remote, tried it again and nothing.
