Dead No Display.

Dear Techs, I have the above mentioned VCR, and I know where the Problem lies. I am an experienced tech. of 32 Yrs.I found 3 bad Caps, two Rectifier Diodes, No Problem with these parts, but I found 2 Shorted Zenner diodes, and I cannot make out the Volt& Wattage on these. And of course all this on the Power supply Board. Do you folks ever send out service literature on Elect.Equipment,? Thanks for your answer. Larry Helton (labethelton@netscape.com)

SOURCE: VCR POWER ON PROBLEM

On vcr power supplies usually first component to go is a capacitor, check if its blown, or test it if you have a meter capable, next check diodes and resistors, also check the resistors and diodes on all the boards( they may have blown if a cap has blown) If there was smoke or a smell its usually a resistor to look for. When you replace them replace them with a higher votage cap.. Example 15v 1000uF cap with a 25v -35v 1000uF cap( this is just to avoid the problem from happening again.

Display shows "brake failure stop safely"


This is a known tech issue with MANY models of Volvo. The problem lies in the electrical connections in and between modules and sensors. Even seasoned Volvo techs have a hard time with this problem. I would definitely take it to a dealership and get a troubleshoot & diagnosis done. As far as I know, there are tech bulletins on the issue, but no recalls. A dealership would have the most recent and effective repair solutions to perform after doing a diagnosis.

Hello, my westinghouse tv has sound but no picture. when the tv is turned on, the pic comes on for a second then goes away. tv is 3 yrs old


You have 1 or more bad lamps in your display panel. You can get replacement lamps, but there is a lot going on to change them. If you are not experienced in electronics, I would suggest you let a service provider fix it, or invest in a new set.

We have a RCA VCR Model VR622HF Manf. 9-18-98 that suddenly won't turn on manually OR with remote. I am an experienced Electronic Tech with 43 years @ ATT. I measured the resistance at the AC Plug and read...


Hi,
If front display lit up when vcr plugged in that means power supply is working and issue is in system control section, and if front display remains dark while vcr plugged in wall socket then power supply is defective.
As you know its an old model vcr so I do not think spare parts would be available any more, I found good option for you to fix this vcr.
Click eBay.com link to get same vcr in working order for $40 that can be used to obtain either power supply or any other board/ parts to repair your vcr.
Hope these info will help you.
Thanks.

Power/Standby light blinks green then screen goes blank (off) for


I have a similar problem. Just found out a possible solution yesterday. I am waiting for my lamp but here's what you need to do if you have replaced your lamp. Go into self diagnostics mode: Switch of your TV via remote, you will see red standy by light. Now,on the remote press "Display"=>"Channel 5"=>"Volume Up"=>"Power Button". All these keys need to be pressed within 3 seconds. You will now enter the diagnostics mode. Press "Jump" on remote (bottom right) 3 times and then press "Channel 2" 9 times. The screen will display your current lamp hours used.

In order to reset your tv to factory settings and for the new bulb to work you must reset this timer or else your TV will assume you are still using the old bulb and will automatically kick in "over protection mode". So here's what you do once you do on the lamp hours display screen. Press the "Channel 3" button on the remote 3 times then "Mute" then "Press Enter" to reset the timer to zero. Your TV should now work as normal. And remember, whenever a part is replaced all factory settings must be reset to zero. To do this, follow "Display"=>"Channel 5"=>"Volume Up"=> "Power Up" to enter service mode. Finally, press "Channel 8" and then "Enter" to put the TV back to factory settings.

The above mentioned is usually performed by a service technician and they charge somewhere around $95 diagnostic fee. You just saved this charge. If you see flashing red lights count them when they flash in sequence. This is a code for the techs to tell them what is wrong. These flashing red lights sequentially flash from 0 to 10 times to identify a problem. Usually, when the bbulb goes bad the only thing that might need to be replaced would be a "lamp Driver" aka "Power Block Assembly" $116.25 online from Sony, or the ballast. Sometimes, if you do not have a video a Thermal FUse can go bad which only costs $4.80 for the KDF60-XS955 but the techs will charge you over $300. You can do this yourself if you can get your hands on a service manual.

Hope this info helps.

Good Luck to you all.

I bought a ps3 from china, got the converter and everything but the ps3 turns green and den quickly back to red


It sounds like it's a major system failure. If you just got it, Sony will honor the warranty and fix it or replace it. As far as I know, there is no fix for this. Myself and a couple other techs have tried MANY repairs for machines like this. I have found that the problem lies within the mother board. Sorry about that. Good luck to you.
