Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

42H83 Occasional shutdown

I'm a servicer. Dead set. Replaced H. Out Xstr and played for 3 days. I noticed today it shuts down occasionally but comes right back on with normal pix and audio. I suspect IHVT.

Andrews, MCM, Tritronics say IHVT, is no longer available.

Might just be dry air and kine discharge.

Anybody had anything similar.

You also should change the thermal paste. If you want to play games, please choose normal PC. I think you are asking too much from your laptop.

Won't turnover occasional click


suspect battery problems. THe positive terminal developes a hard black coating inside the lead terminal and around the battery post Remove this using rough sand papaer to a shiny finish on both units . Repeat the operation on the negative terminal. Try the starter again. If still nothing turn on the head lights try again noticing if the head lights go dim. IF they do check if the battery is charged OK then you have a problem in the starter motor IF it works some times and not at others you probably have a dead bar on the communator which means a replacement s-motor

2000 Toyota Camry drains battery when shut off


Did the mechanic not check for current drain with an
amp meter & see if everything timed out after ignition
is off & door closed & was within milli-amp spec

I don't think people explain why they are at a shop or
the mechanics have little skill or patience for some issues

My XAV500 units shut down on an irregular basis


Well, you didn't actually ask a question, but let's assume you want to fix the intermittent shutdowns.
I've used XAV500 (it may be called XAV 5001, not sure) and also the newer Netgear powerline adapter commonly called AC1200. Both have the same problem of occasional, intermittent shutdown. The XAV 500 problem seems to be that it goes into "sleep" mode to save energy when it's idle/unused for some X amount of minutes. The problem is that it doesn't wake up again! The only way to overcome it is to unplug it from the AC power outlet for, say, 10 seconds, then plug it back in. I never found a firmware update for this model at Netgear's support website. The newer, faster AC1200 model also intermittently ceases to work. With this one, I simply wait a couple of minutes and it comes back on. If I'm in a hurry, unplugging for 10 seconds also seems to work. Originally, I thought maybe our Router was the problem, but over the years we have replaced that Linksys router (and the ethernet cables) with a model from Western Digital, and more recently with a TP-Link, each being an alleged upgrade on the previous ones! But, the intermittent loss of connectivity continues. The other possibility, of course, is that our internet service provider Comcast/Xfinity has occasional brief outages; maybe some Xfinity installer working elsewhere in the neighborhood turns the service off while connecting or disconnecting something, who knows?

Samsung model HLP4663WX/XAA with loud buzzing noise, need to know which part to replace.


See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

Occasional miss or hesitation while driving will also do this at idle have checked points and set at 20 thou have changed plugs set timing at 7btdthen advanced a little after no change leads are only...


You set the gap at 20 sould be 16,a hesitation or occasional miss is not from the points or condensor, its from the craburator,its a power valve or your float getting the hesitation can be the secondary not feeding at wide open throttle, the carburator is faulty, and plus todays fuel is not meant for carburators
