My Panasonic DLP television suddenly lost picture, went to snow and lost audio. What is wrong?

Couple things. If the color is going out, you probably need new bulbs. Easy to change, get em on Ebay for pretty cheap. I had an LG DLP and the pic would go out with big changes in the barometric pressure, and also from over heating. Call manufacturing and let them know you're not happy. They extended my warranty for me.

Hiya!

Sounds like it's on the wrong input, maybe it's analog tuner. Have you tried changing it's input?

It's the optical block (color wheel) and the same thing happenned to our Philips 50" DLP. From what I've read, it's not worth the trouble & $$ to fix. Dig a hole!

Well the LG tv is not getting the cable signal.Unplug the cable box about an hour.Replug the box let the software to upgrade the cable box.The LG tv should get the signal back as normal.Not,than the LG tv Tuner board have problems it dead.Tries Websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.

you have lost one of 3 things,Antenna/Cable, Tuner or part of your tv's power supply

Did you replace the lamp because the picture went out (black)?

check the backlight inverter and the Y-sus board the one to your left. if those are fine check the bottom right buffer board

Check your lamp; it may have blown. Sound, no picture and a red light are classis signs a lamp has failed.

Mikey,
There are any number of possible failures that can cause the symptoms you're describing. For example, C509 a .47uf/250v mylar cap has been known to fail in those units causing the wavy lines. On the other hand convergence amp failures can do the same thing. That unit uses two STK392-110 Sanyo amps at pos# Ic7001,Ic7002 Panasonic p/n# C5aa00000203 and more in that circuit needs to be tested and signal traced to isolate all of the problem if the amps are the culprit. In short, I don't think this is one you want to tackle with less than a 20 mhz scope and some serious background in electronics.

CHECK OTHER TYPES OF VIDEO INPUTS. IF USING COMPONENT VIDIO CHECK YOUR CABLES ARE ALL MAKING GOOD CONNECTION, YOU CAN USE AN AUDIO CABLE TO CECK INDIVIDUAL COMP. VID. CABLES TO MAKE SURE THE CABLES ARE GOOD.
