Question about Toshiba 42DPC85 42 in. EDTV-Ready Plasma Television
Recently i left the room for a few minutes and returned only to find that my plasma had no picture. the sound was there and all of the menu features seemed to respond to command attempts but still no picture. i changed the input, cables, tuner box etc. the problem is obviosly with the tv. any ideas???? no plasma repair within 150 miles of my location. i;m pretty handy if i knew what to check.
I bought my Toshiba 50HP66 50" Plasma a little under 18
months ago and about four or five months ago it began to act strange. It would put a block of characters on the
screen that made no sense until I would unplug it and and restart it. Then it would act normal for awhile and would
just need a reset every so often. I was
out of the 12 month warranty so I just put up with it.....until yesterday. I was watching the TV when out of nowhere, I
heard a really loud POP....and then the screen went dark. I went ahead and bought a new Sony LCD screen
and was going to sell this for parts online.
I troubleshoot electronics daily so I thought I would purchase a digital
copy of the service manual and check it out.
After I downloaded it I noticed that this is very common with plasmas
(this exact failure) and only on the LG boards.
I scanned my handy dandy service manual and found out that Toshiba was
using these same boards along with Zenith and some others. The difference is all the other manufacturers
honor their product and replace these boards even when the warranty has expired
so I called Toshiba and tried my luck.
Even though I've found many postings of Toshibas failing and hundreds
and hundreds of the exact same board failure...Toshiba claims to have never heard
of it. I informed the "Customer
Support Supervisor" of Toshiba that I would be willing to post this on a
few websites and have other customers contact him to inform him of this issue. He was fine with it so here is his contact
information so feel free to let him know your Toshiba plasma went POP as well.
800-631-3811 ask for
Dave Thompson and let him know.

This has nothing to do with Toshiba in particular.
This TV is, in fact, manufactured by LG and branded to Toshiba.
The actual plasma part of it , anyway.
We service Y sustain boards like the ones in 50HP66 and 42DPC85 and for a whole lot less than what you'd buy from places like MCM or merchant-online.
In fact, I dare say a serviced board is better than an original used board pulled from a working TV that was disasembled for parts.

This is a common problem on these plasma TV's. The problem resides in
the high voltage boards known as the X and Y Sustain boards.. You can
purchase them here for a very reasonable price:
http://www.discount-merchant.com/Y-SUSTAIN-FOR-42-PLASMA-TV-PN-6871QYH036A-p/sku9510.htm
The above link is to a Y-SUS board. The X-Sus board is often the 2nd cause of failure and can be found here:
http://www.discount-merchant.com/X-SUSTAIN-6871QZH041B-6870QZE017D-6871QZH052D-p/sku9509.htm
To
test which board is failing, you need to check voltage input to the
YSUS board first... Input should be 120V from Power supply, output
should be above 250V.. Do this test with XSUS disconnected. IF 250+V
exists, then XSUS is damaged. If not, then the YSUS is the faulty part.

Just great. It's Christmas Eve and POP goes the 42HP66. Sound still works BUT the picture is kaput! This is ridiculous. Granted, it is almost 4 years old so I guess I'm doing better than some people on this board, but my old style Toshiba with a good old fashioned tube lasted 8 years. I replaced it with this unit to upgrade into the 21st century. $2000 dollars at HHGreg for 3 years and 8 months of service. What a joke. Toshiba should be ashamed.

Just took our Toshiba big plasma tv into shop in town,to a reputable repair place. We also had no picture one day when turning on tv.Sound was there,could change channel,but didnt know what we were changing channel to.Our TV repair guy said there was a short in it,and had to do further troubleshooting to find where short was coming from.Just found out today,it was a very expensive part that was blown out by the short.And the tv guy said that the tv just got too hot which created the short. anytime solder gets too hot,creates sort of a melt down to connections,any cracked(caused by cold solder joints) or weak connections are the first to go. The tv cost us approximately $1800 on sale,and it will now cost us about 650 dollars to replace the very expensive part that was blown.The tv guy says,just like the instruction manual says,make sure tv is well ventilated,dont leave on all night or extended periods of time,hence,the overheating.But what the manufacturers dont say is that these plasma tvs should have a fan built into them because they do have a tendency to overheat easily. If you are lucky,it wont be as expensive for you to get fixed.We are foregoing getting it fixed as our tv guy recommended not buying plasma's for that reason.Just going to cut our losses,he offered to buy if from us. Live and learn,unfortunately a very expensive lesson about modern electronics,this coming from someone who worked in the computer electronics assembly industry for over 20 years. Should have checked it out more thoroughly

Last night I was watching tv on my 50hp66 and the picture started to scramble, turned all different colors and then went black. I turned off the tv for a few minutes and it came back with no problems for the rest of the night. Well tonight we were watching tv and suddenly the screen went black but we still have audio. When we try to turn it on it flickers from grey to black. This really sucks since the tv is just under 2 years old and we paid like $3000 for it at Tweeters. I will never buy Toshiba again.

I'm having the same problem. I got my TV on sale too. The repair says TV parts also very expensive. I will not be purchasing a plasma ever again. I only had my TV for 18 months and never got the extended warranty, shame on me. Live and learn
Our Toshiba 42HP66 picture just went out after owning the $1700 plasma television for only 18 months. We can hear sound, but the screen is black and the television does not seem to respond to changing input commands. We contacted the Best Buy where we purchased our television and they said since we did not purchase the extended warranty, there was nothing they could do. We were then told that the cost of repair would nearly equal the purchase price. We also contacted a customer service representative at Toshiba who also told us that they could do nothing for us. Is a $1700 television supposed to be obsolete after one and a half years? Is there anyway to repair these? I don't plan on ever purchasing another plasma television.
recently i left the room for a few minutes and returned only to find that my plasma had no picture
the sound was there and all of the menu features seemed to respond to
command attempts but still no picture. i changed the input, cables,
tuner box etc. the problem is obviosly with the tv
had the same problem sound but no picture took it to a local tv repair shop an he replaced 3 panels at a cost of £180 jobs a gudden
I have only had my plasma for less than 18 months, my dausghter was watching tv and it just went black, we had sound for a little bit but when tv was turned off it went out as well, now all we hear is snow and a blac screen, I have not taken it to a repair person as of yet. like others we did not purchase the extended warranty so we will porbably be out the money as well, any resolution would be helpful.
Just like everyone else wrote in, the TV just went black when I left the room. Sound, but no picture. I had the unit diagnosed at a reputable (but expensive) repair facility. Apparently the y-z controller assembly has malfunctioned and requires replacement. The cost would be $ 345.00 (Can) and $225.00 labour. The TV is 18months old and barely gets used. This is nothing short of ridiculous. I'll never buy another Toshiba product again as they were less than helpful and would not even listen to my concern, let alone contribute to the repair. The unit cost over $2200.00 at the time. You just lost my business Toshiba!!!!!!! Does anyone have access to Toshiba parts?
I had the same problem occur to me. Repair shop said 3 boards failed and the repair would cost over $400. I contacted Toshiba and they are not interested in helping cover the cost in any way. Apparently there was a design flaw with the set that allows the circuitry to overheat. This resulted in a direct short that basically let the smoke out of some capacitors. We live and learn. Short answer is don't buy from Toshiba. You will probably end up regretting it.
i have a 42'' hp66 have the same problem.
50 inch hp66 same problem 2 years old!!!!!!!! Two grand for a tv that needs five hundred dollar repair in 2 years!! Toshiba knows there is problem just look at there new design. They just know they have us over a barrel and are not willing to help!! Never another penny spent on Toshiba products save your money buy Sony I know we sure will. Had Sony for years no problems should have n
