HLR5667w - Video goes blank after 1 hour, but audio still works; no error message; already replaced lamp; happens with both analog and digital sources

I would guess that it could be the main board going bad. Check all our connections and wiring. You should call places like Tri-State Module and they can probably send you a part or repair for way less than 500 bucks.

The sattelite box have issues,tries unplug,replug the box back like about an hour later for it to reboot and resetting and upgrading it softwares.This tv problems switching modes to digital and to analog again back and forth should be solved.Still happening the box have problems,call ur sattelite provider change the reciever box.

Part 1

Let's establish a couple of things first.

1) You already have the turntable part working.
2) Your receiver has a defeatable Tape Loop.

Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.

The connections themselves are fairly simple but it pays to understand what happens in the loop.

In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).

Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.

The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.

EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.

In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? The rest would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that

The tv projection lamp inside the tv now is already been in it like a 1 1/2 or 2 years already?Yes.Than the tv projection lamp life is up and over.Replaced the tv projection,should solved this problems.

two things to check here:

1. remove the lamp and examine it to make sure it is not shattered inside.

2. if the set had a high pitched or fan like noise before it failed, the color wheel needs to be looked at--I can tell you a easy way to do this.


Look at the lamp first--life span is 2000 hours.

I am here to help and the more you tell me the better I can help you.

Yo learn how to replace the lamp go to link below and page 133 will tell you.

Hi,
Well for what you're describing it could be 2 things,It sounds like the lamp is acting up on you,basically if you have a generic lamp it could last you from 3500 to 4500 lamp hours and if you have a Phillips lamp that could last you from 6,000 to 8,000 lamp hours,Now if you have already replace the lamp and you still get this problem it could be that your ballast is to weak to power the new lamp.you can go to http://www.fixyourdlp.com/?click=52978 they have really good post and videos.

Good luck

Digital-to-Analog Converter - DAC When referring to Audio, DAC is also short for Digital-to-Analog Converter and is the process of converting a digital signal into an audio signal.


Random Access Memory Digital-to-Analog Converter - RAMDAC Pronounced Random Access Memory Digital-to-Analog Converter, RAMDAC is the ... the digital data to an analog signal to be displayed on a computer monitor.

Good Luck, Please dont for get to Vote/Thank you.

repairs up to 50 % of replacement cost are reasonable , if warranty is same as new ( if warranty can be extended - resale improves ) ;
