Toshiba TheaterWide 52HM94 HDIM Input


The 52HM94 is a somewhat older set--best guess is it is not compatable for this use.

Toshiba 50H81 very dark, blurry picture on all inputs.


check if the problem looks zig zag looking or it its not present in the PIP window. If so this may be an issue with the hypermodule - you can google TV repair Kits to find parts.

Are you using the rf antenna input for TV or 1 of the VIDEO inputs from a cable box or sat receiver. If the latter check to see if you unplugged the audio fron the box White and red wires from box. If thats ok Plug that dvd player into that input using the cabes from the dvd player .If you now have sound change ables from box. if still no sound cable box bad. If still no sound from that input check for solder connection on input jacks. If antenna input is used replace the tunner intv.

Unable to view DVD on TV


Here is a solution buy a coax to RGB converter they run from $20- $30 at radioshack this will shore up that problem as it will use channel 3 as the input of choice.

Satellite input


Most tv setups require that you change the input source to gain the ability to watch the proper peripheral e.g. if satellite is connected on video one and the dvd is connected to the tv on another input such as video 2.

If the satellite runs into the dvd unit and from there the dvd is connected to tv you may have to power off or on the dvd player to resolve conflict.

Another problem may be the resolution setting if your tv is Hi Def. Set the tv and receiver to the resolution e.g. 1080i.

You can also changed the way the satellite is connected to the tv possibly if you have other inputs.

Check the channel also, if the unit is connected with coax it would more than likely need to be on ch 3 or 4 if you are at the satellite receiver box location. If you are at a stand alone tv off of a dual tuner you may need to search the channels for the right source both air(analog) and cable(digital).
Hope this helps you out. If I can be of more assistance let me know.

Green Plaid then Vertical Lines, Failure of hard controls, Analog Board?


You are absolutely correct, When anyone complains of vertical lines or bars, the next step is to see if it happens on only digital inputs ( digital board ) , only analog inputs ( analog board ) , or both ( DMD board ) .

Analog board can be purchased at www.partstore.com ,

Hi guys, don't know if the previous post got through. Have a new LCD tv and DVDr, connected with a HDMI cable. when DVDr switched off analogue and digital picture is fine. as soon as dvd is switched on...


yes, hdmi will give you better results..
are you running hdmi to hdmi connection on tv from cable box?
if so, that is correct but as for the dvdr, what tv port are you connecting it to? i would use another hdmi cable for the dvd too for best picture resultif it's an option on your dvd.. you should have multiple input outlets on your lcd with 1-3 options for input devices via analog or hdmi.. so analog is not hdmi--hdmi is digital so it switches to the hdmi resolution when you turn it on..

let me know how it goes and if i was helpful involving resolution.. helpful feedback is appreciated.. thanks, d

your dvd player should be set to a different

Dvd plays fine sound/picture...No sound or picture with cable input


John,
To answer your question no, there are no fuses associated with the tuner input - through the "F" connector jack.
You have there a V26 chassis which has, among other things, standard digital and analog signal inputs. If one works but not the other - and you've verified it's not the cable then the only alternative is the signal board, Mitsubishi p/n# 930b923002...
But don't rush out and buy this puppy, it's a fairly expensive board and there are alternatives to replacing it new or used - PTS Electronics can rebuild this board for half the cost of a new one and most techs use PTS for that reason.
My best advice is to have a qualified shop estimate the repair and if they decide that the signal board needs to be replaced and quotes you a price ask them then about having it rebuilt.
Also take the unit to them to save the pickup/delivery charges and ask for your estimate in writing...
Hope this helps!
Bill

Toshiba 52hmx94


This denotes a possible problem in the high voltage power supply. The HV power supply controls the voltages that control sceen activity. If you do not have electronics experience I would suggest taking the set to a TV repair shop.
