Dome/Map/Cargo Light

1. Disconnect the negative battery cable.
2. Remove the bulb from its retaining clip contacts. If the bulb has tapered ends, gently depress the spring clip/metal contact and disengage the light bulb, then pull it free of the two metal contacts.

To install:

1. Before installing the light bulb into the metal contacts, ensure that all electrical conducting surfaces are free of corrosion or dirt.
2. Insert the bulb into the holder. If the contacts have small holes, be sure that the tapered ends of the bulb are situated in them.
3. To ensure that the replacement bulb functions properly, activate the applicable switch to illuminate the bulb which was just replaced. If the replacement light bulb does not illuminate, either it is faulty or there is a problem in the bulb circuit or switch. Correct as necessary.
4. Install the cover until its retaining tabs are properly engaged.
5. Connect the negative battery cable.

Instrument Cluster Light Bulbs
The instrument clusters installed on these models are one of 2 types and distinguished by the instrument lighting color, either green or blue.
On models with green instrumentation, only the control light bulbs are replaceable. Should any other failure occur, the instrument cluster must be replaced.
On models with blue instrumentation, none of the components are replaceable. Should a failure occur, the instrument cluster must be replaced.

Map Lights

1. Disconnect the negative battery cable.
2. Remove the bulb from its electrical connector.

INSTALLATION PROCEDURE

IMPORTANT:

• Replace a high beam bulb with another high beam bulb. The high beam bulb has a red gasket.
• Replace a low beam bulb with another low beam bulb. The low beam bulb has a gray tip and a yellow gasket at the base.

1. Install the new bulb to the headlamp assembly by twisting the bulb clockwise in order to lock in place.
2. Connect the electrical connector to the bulb.
3. Install the headlamp assembly.

Hi,

First step is to unplug the 120 vac power for a few minutes to clear any corrupted data that may be present in the controller circuits.

If a "power" reset doesn't help and the lamp or bulb is installed correctly, you most likely have a failed replacement bulb. The symptoms are all standard indications of a failed bulb.

Reduced lamp life can be caused by:

1. Lightning and other 120 vac power bumps.
2. Collisions with vacuum cleaners or other incidental impacts while the TV bulb is operating.
3. Starting the TV without a complete cool down. Bulb will consume a small amount of mercury with each start. Excessive consumption occurs when bulb is "Hot" and turned on.
4. Wrong bulb installed as replacement.(Philips original replaced with Osram or El Cheapo)
   
5. Poor quality or damaged bulb installed as replacement.
6. Bulb damaged during replacement
7. Bulb installed incorrectly at replacement.

Almost all Hitachi 55vs69 "No Picture" failures are related to the bulb.

Many of our service events are with customers that purchased El Cheapo bulbs from "shopping cart" websites or picked up a bulb from a small "local" TV shop. Many small shops stock of 3 or 4 bulbs and try to substitute or cross reference to fit more than 200 models of TVs from 7 different manufacturers. If a premature bulb failure occurs, they have the opportunity to sell you some expensive service.

Release the locking ring, then withdraw the halogen bulb from the headlamp assembly


Removal & Installation

This procedure only applies to replaceable halogen headlight bulbs (such as nos. 9004 and 9005); it does not pertain to sealed beam units.

1. Open the vehicle hood and secure it in an upright position.
   
2. Unfasten the locking ring which secures the bulb and socket assembly, then withdraw the assembly rearward.
   
3. If necessary, gently pry the socket's retaining clip over the projection on the bulb (use care not to break the clip.) Separate the bulb from its socket.
   

To install:

1. Before installing a light bulb into the socket, ensure that all electrical contact surfaces are free of corrosion and dirt.
   
2. Line up the replacement headlight bulb with the socket. Firmly push the bulb into the socket until the bulb is seated. If so equipped, make sure the spring clip latches over the bulb's projection.
   

WARNING Do not touch the glass bulb with your fingers. Oil from your fingers can severely shorten the life of the bulb. If necessary, wipe off any dirt or oil from the bulb with rubbing alcohol before completing installation.

1. To ensure that the replacement bulb functions properly, activate the applicable switch to illuminate the bulb which was just replaced. (If this is a combination low and high beam bulb, be sure to check both intensities.) If the replacement light bulb does not illuminate, either it too is faulty or there is a problem in the bulb circuit or switch. Correct if necessary.
   
2. Position the headlight bulb assembly and secure it with the locking ring.
   
3. Close the vehicle hood.

HEADLAMP BULB REPLACEMENT

REMOVAL PROCEDURE

CAUTION: Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:

• Turn off the lamp switch and allow the bulb to cool before changing the bulb.
• Leave the lamp switch OFF until the bulb change is complete.
• Always wear eye protection when changing a halogen bulb.
• Handle the bulb only by its base. Avoid touching the glass.
• Keep dirt and moisture off the bulb.
• Properly dispose of the used bulb.
• Keep halogen bulbs out of the reach of children .

NOTE : Avoid touching the bulb or letting the bulb come in contact with anything damp. Oil from your skin or moisture on the bulb can cause the bulb to explode when the bulb is turned on. If either comes in contact with the bulb, clean the bulb with alcohol or a suitable degreaser and wipe the bulb dry.

1. Open the hood.
2. Remove the headlamp. Refer to Headlamp Replacement .

1. Remove the access cover from the rear of the headlamp.

Fig. 5: Once the bulb is removed, inspect the socket for corrosion
To install:

Before installing a light bulb into the socket, ensure that all electrical contact surfaces are free of corrosion or dirt. NOTE: Before installing the light bulb, note the positions of the two retaining pins on the bulb. They will likely be at different heights on the bulb, to ensure that the bulb is installed correctly. If, when installing the bulb, it does not turn easily, do not force it. Remove the bulb and rotate it 180 degrees from its former position, then reinsert it into the bulb socket.

Insert the light bulb into the socket and, while depressing the bulb, twist it 1/8 turn clockwise until the two pins on the light bulb are properly engaged in the socket.

To ensure that the replacement bulb functions properly, activate the applicable switch to illuminate the bulb which was just replaced. If the replacement light bulb does not illuminate, either it too is faulty or there is a problem in the bulb circuit or switch. Correct if necessary.

Install the socket and bulb assembly into the rear of the lens housing; otherwise, install the lens over the bulb.

Insert and secure the lens assembly into the body of the vehicle.
