Did you get a 5 error on the led? If so that is caused when both pin 95 and 96 of IC6902 on the G2 board are both low. You will need a new G2 board. If you go to the link I am posting here they can get you a new G2 board 169.84. You just have to hit the contact them link on the lower left side and leave your model number along with the board youre needing. I bought one last week so I know the price of thier boards.

I have a JVC-HD projection TV model 56G786 and all of a sudden it will not power on. When you try to turn it on the blue light on the power button goes on but after a few seconds it starts flashing and...


Hi,

The JVC 56G786 users manual will not give you a clear or specific answer about confirming bulb failure with the LED lamp or power indicators located on the front of the TV.

If the TV was operating normally for an extended period of time (months or years) and will not start, the problem is almost always bulb failure. If the "Lamp Replacement" warning previously appeared "On-Screen" and the TV will not start, bulb has failed.

The first step in a "no picture" situation with a JVC LCD Rear Projection TV is bulb replacement. There is no way to measure the bulb. Sometimes the bulb is visibly broken or damaged when it fails. Remove the lamp cage and have a look.

The JVC Lamp Gallery has all the JVC models and lamp numbers listed. There is also a link to DIY JVC bulb and lamp installation.

If a good bulb is installed correctly and the TV still does not start, you need a technician. There are no user serviceable parts other than the bulb. Failure of ballasts, power supply boards or controller boards is rare in these TVs.

The lamp light is blinking once every 5 seconds. The manual says that " Lamp will not light or light is abnormal"


HI,

Panasonic PT50LC13 lamp indicator blinks to tell you the lamp is faulty.

You need to replace the bulb or TY-LA1000 lamp assembly. This link displays all Panasonic TV Lamps and TV Bulbs. This page shows Panasonic lamp location and How to Replace TYLA1000 bulb. TY-LA1000 Bulb Replacement requires the use of a long Philips Screwdriver to reach screws within the lamp cage.

Unplug AC power before removing the lamp and re-install all doors, etc, correctly before starting the TV. Vacuum any visible dust or lint from air vents and lamp area. Do not used forced air to blow out dust, big problems may result.

The user's manual has a description of what the Blinking LED indicators mean.

Whre is the location of the bulb on the tv?


I found the location to get at the lamp. If you are loking at the front of the TV there is a small panel at the bottom of the right end. Two screws, remove panel, two screws inside and a small handle that lifts so you can slide the unit out. 4 screws on top of the cage that the lamp sits in, carefully slide up the silver bracket holding the bulb, be careful the edges are sharp. Remove the bulb from bracket and remove the 2 cables attached to the bulb. Now just do the same but in reverse. Make sure you wear plastic gloves that should be provided because if your fingers touch the lense you could be out the price of the lamp.

Nothing happens when I try to turn tv on. The protect LED keeps flashing on board and thats all.


You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

Replaced old bulb with new bulb (same model), and the TV doesn't turn on. The bulb cage is in, and the back vents are on. For what ever reason the circuit must not be completing because it's not turning...


if the old lamp is still working, try it on just to make sure the new lamp is working, which more than likely it is GOOD. If you hear a clicking, buzzing. you may have a ballast problem. Meaning that this small board is responsible for providing your lamp w/ the correct voltage, and it might not be able to light up your lamp.

Samsung 50" DLP - Lamp Light Blinking after bulb replacement


Listen closely. The tv should make a high pitch whine as it turns on. If it does wait and see if it tries this a few times. If yes then check the bulb, I have seen cases where the lamp shoves the power connector back into the set. If the tv starts with a grown or heavy vibration noise, then your color wheel may have broken and needs replaced.

Lamp(lite bulb) is dead - need to buy replacement and install it


Click here to find the lamp for your TV. You will still need to use the existing cage assembly, once you remove the old lamp you will be able to see how it's assemble.
For the lamp replacement instructions, you will need to download the owner's manual and go to page 16 to 22 to know how is done.

Good Luck.

I have a viore monitor ipt46dl30 which just went black but we can still hear the voice.. help?


I'm in the process of ordering a replacement bulb for a friends set right now. The information below is exactly what's needed to get the correct bulb for this DLP television.

TV Make: Viore

TV Model: IPT46DL30 (Confirmed to be on TV label)

Bulb/Lamp Model: SHP70 (This number is right at the top of the bulb/lamp, where the wires connect)

Housing Model: 140-1027 (This is also known as the Ballast which houses the bulb/lamp)

Now, I've managed to locate the bulb/lamp from a few different sites. Unfortunately, there doesn't appear to be a reputable manufacturer making aftermarket bulbs for this DLP model. The original bulb type is all we have to look forward to. The cheapest price that I've found so far is $120.00. I have also found these particular bulbs for as high as $295.00. Needless to say, I'm going with the former.

http://www.replacementlightbulbs.com/lampshp70.html - $120.00 (Buying)

http://purelandsupply.com/140-1027-Bulb-Akai-DLP-TV-Lamps.html - $277.90 (Too much)

http://www.encompassparts.com/products/?140-1027 - $295.00 (Too much & very skeptical)

Lamp location


No, that was wrong advice. On this model, there is a large door on the right side (as you face the screen) of the TV at the bottom. Remove several screws to take the cover off. Inside, looking along the back of the TV (not toward the screen), you'll see what looks like a wire bail (handle) on a square inset piece about 3 inches square. Remove the screws and pull on the wire bail and the lamp housing will come out with the lamp contained inside. Make sure you unplug the TV before doing any of this. If you are replacing the entire housing with a new lamp you can just plug in the new housing and replace the screws and cover. If you are placing a new bulb in the existing housing you take off 4 small screws and remove the metal cage from the housing, remove and replace the bulb the same way the original is in there, put it back together, and you're done.
