Question about Mitsubishi WD-65638 65-Inch 3D-Ready DLP HDTV

Open Question

DLP screen is pulsing. Shouldn't be a lamp issue.

My issue started out as an occasional green tint that would flicker across the screen. I assumed it was the color wheel, so I replaced it. No change. I put the old color wheel back in, and replaced the DMD board (not the DLP chip). Still no change, so I put the original board back in. The problem has now progressed to what seems to be a pulsing of the screen. The picture appears to change saturation in a constant flicker. I've tried replacing the lamp itself several times, with no change. The TV has never shut itself off or displayed any warning lights. I hate this TV...

SOURCE: Lamp Light Red - No Screen Image

It could be the a problem with the lamp ballist circuit, or just a bad lamp socket, or simply a bad lamp. The only way to tell is to call out a servicer as that would be alot less expensive then to get a new lamp and then that not be the problem. These problems can be a little hair pulling at times, thats why i have no hair left!! LOL Good Luck

SOURCE: Replaced lamp and now can't get a picture

Hi Sally Jo, Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 3. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977010 4. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977010 5. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977010 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 934C148001. Hope this helps!

Wd65738 flickering


I had a TV do that about a year ago, the repair man said it was the color wheel inside the tv. I changed the bulb to see if he was BS'ng me and eventually got the manufacturer to send a color wheel and I change it myself, was very easy...TV works fine ever since. Hope this helps

I have a hitachi 50vf820 with green tint to it


Its a DLP type set that uses a lamp for a light source.

With the color turned to zero stand back and examine the image.

If mostly all green or areas are green you may have a issue with the optical light engine--either damaged inside from the heat of the lamp or the portion that processes red, green, and blue information bad.

DLP RCA HDTV is displaying bars from top to bottom of screen, with green tint. Is this the light engine going bad?


Hi

Thanks for using FixYa. This issue can happen due to a faulty light engine or due to a a faulty DLP Lamp. However, it can be an issue with the video driver card of your Card. I'll suggest to use a DVD player and check if the tint is still there. If the tint disappears then its an issue with the video driver card.
However, if it doesn't correct the issue its either a DLP Lamp or a faulty light engine.
Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Before performing any repairs i'll suggest you to try and reset the TV by unplugging it for 8-10 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

Blue Flickering Screen - Which Repair Kit?


yes they provide a free service manual with their kits. the symptom of the blue screen could either be the signal or the FMT as they can both cause those symptoms, My professional guess would be the signal board as the FMT will cause distortion lines across the screen with no picture.
