My television makes a screeching noise and you can see a light in the front, it won't turn on

Whoever seabelow is, doesn't know about tv repair. You have a projection tv with 3 picture tubes. It doesn't have a color wheel. Maybe he is a tv salesman needing commission. Anyhow your tv has a major problem. The sqreeching noise you hear is probably a picture tube arcing. What happens is connections on the circuit board break free and the high voltage goes too high causing the tube to fail and spark. If you want to confirm this you can remove the rear cover which uses star type screws. Then remove the 6-8 screws from each side by speakers. Pop off front cover and remove small door in middle of set. Get extension cord and stay back from set. When you plug it in and apply power you will see which tube is arcing. Unfortunately, if this is a correct diagnosis, you will probably end up replacing the set unless you find a used picture tube to replace the bad one. Even then you still need repair to the deflectoin pcb. This is about a 400.00 repair. Sorry for the bad news but I though you at least deserved a compitent response. Good luck, Russmann.

Panasonic PT-61LCX65 61" Television Set Popped, Now Left with a Cicking Sound

Your problem more than likely lies in your lamp. The whirring noise you hear is the ballast trying to fire up the bad lamp. The lamp part # for your set is TY-LA1000 and can be purchased online at vance baldwin. This is something you can easily replace yourself and your owners manual will give you instructions. Hope this helps

Repeated convergence problem or something new?

Sounds like you lost the High Voltage. The beating sound is the power supply trying to start up. After a predetermined time it will quit to protect the set. This is a very common problem and typically not that much to repair. If you are not an electronics repair technician you should find a reputable repair shop and enlist their services. I would not think the cost should exceed $150.00 to repair. Good luck.

Jumping picture for a few minutes

theres a bad capacitor off the sweep power supply or possibly in the main power supply. Most likly though it would be where i mentioned first. There are no user serviceable parts inside this set Unless your a repair person so best thing for you to do is call in a pro to assist you in this repair. Good Luck
