P50pdtv10a will not change channels stuck on channel 3


Hello
The system memory IC of your TV has damaged. This is one, which stores all the setting we have done with remote control, including channel memmory. This IC works in conjunction with the main system control IC. When we switch OFF or do any other adjustments with the tV, all the data will be stored in this IC, and tetreived from it to main system IC to process when we switch ON the TV. This is a non-volatile memory chip, ie, even the power is OFF, the data stored in it won't lost. This is a very small IC, can locate very near to main system control IC. Will have 8 solder terminals [normally], and ver cheap to buy too. Even though it is a very cheap and small one, the function of it in the circuit is great. In some Vizio sets, this IC will be of SMD [surface Mount Device] type, and on othere will be a DIL [Dual In Line] type pin confujuration. If your TVs memory is of first as stated above [SMD], replacing it will not be an easy job. If it is of second type, it can be replace easly.
Anyway, this is not a work that can be done without skill. If you have enough knldege in electronics, and have a concept of desoldering and soldering, have all soldering equipments with you, you can do this work by yourself at home. Otherwise you have to seek assistance from an experienced service technician. OK.

When you trun on my panasonic PT-61LCX65 tv it makes no sounds the light blinks green. and then red and turns off. what is wrong. i have looked at the buble and it looks fine.


Hello,

does the TV bring out sound even as the screen display is dark?

How long have you been using this TV and have you ever changed the lamp/bulb? Problem should be from the TV lamp/bulb.
Have the lamp replaced and hopefully, your screen should be perfect as before.

Let me know if you need directions in replacing the lamp, even though it is very simple replace.

Yours sincerely.

We have a picture but no sound, it is hooked up to our surround system and the dvd and radio work and we have sound coming out of the speakers but no tv sound....help


Try switching the external/internal speaker switch on the back of the tv to internal. This way you should at least get sound (from the TV not the sound system) when you change the volume of the TV itself.
Explain your set up if you need more help. By that I mean what do you have hooked to the TV and sound system, Satellite or digital cable box DVD ?
Make a note of where all the inputs to the sound system come from.

Tv will turn on but no picture and sound.


If its still both picture and sound there is a few things.First your T.V. could just be mallicous and could be trying to kill you via annoyment.Not likely.The second is the cords in the back are mixed up.Usually they are in the colors of Red White and Yellow.If they are in the wrong analog slots then even though they are plugged in,they wont work.Or it could be age,frayed wires,or any number of things.Hope it helped.

Tv wont respond because device menu is changing through each device


I had a similar problem: my WS-55511 would not respond to the remote and the front control buttons (with the exception of Power) cycled through the Device Menu. I solved this problem by disconnecting the front panel. Here's how to do it: 0. Unplug the TV
1. Remove the speaker grill from the front by pulling forward: there are no screws. 2. Disconnect the two cables that are exposed after the grill is removed. 3. Plug the TV back in, wait for 5 minutes to reset. 4. Try using the remote.  Hope this helps!
