    I am having the same issue. I have only had this Tv now for about 8mths.and now when I hit the power button on the remote the yellow light just blinks but the tv will not come on. Under normal circumstances the yellow light would blink a couple of times then it changes to green and the tv turns on. Now NOTHING!!!!! Please help.

    Same here... TV is 13 months old.

    It started doing it when the TV was 9-10 months old, so I changed the Power Settings so the TV was in Standby mode instead of turning completely off (no yellow light) and it solved the problem... until today! The TV won't turn on again and I'm out of warranty by about 40 days!!!

    Same problem, only with 32HL67U.

    I have a Toshiba Model 42HL117 that suddenly lost power while watching a program. I tried the fixes in the owner's manual to no avail. The TV remains in power up mode (yellow lcd blinks three times). Ironically the unit is 21/2 weeks out of warranty and I understand that LCDs are expensive to repair.

    We had the same problem with ours, maybe the company should receive all these posts. Just a thought...

    Same problem 1 month left on warranty so hopefully Toshiba has that covered. I wondering if there is a long term fix for this problem or if in another 6 - 9 months I'll have the same issue without the warranty to cover the repair.

    Toshiba 42" LCD HDTV and screen went blank within 43 days! Yellow lights is the only part working. Did everything to troubleshoot. Called Toshiba Customer Service. Closest repair shop is over 50 miles away and said they won't come to where I live. The repairman said, "that is what you get for buying it on the internet". (Purchased through Newegg on the net)
    Called CS again they said they would see if they could find a local repair but would not commit to a date. They also sounded as if they care less! I am going to call my credit card company tomorrow and see if I can do a chargeback on my VISA Gold card. I am so mad ... I need to get even with someone!!!

    I have the Regza 37" and when I turned it on last night, it wouldn't power up. The standby light just kept blinking, 3 blinks at a time. Unplugged it over night and it came on this morning. The TV is just over 1 year old (23 days over warranty!!!), but thankfully I bought it at Costco, which extends the manufacturer's warranty to 2 years. I guess I'll plan on taking it back.

The problem is with the signal board. Basically, it is not allowing the power signal to go from the on button from the set or the remote to the TV. I am having the exact same problem with my 42" LCD Regza. Currently, if you are under warranty, Toshiba does not have these in stock. They will not have them available to send until early January. My TV has been at the repair shop since December 4th. I am very upset as I won't be able to watch the bowl games in HD. If your set is still under warranty then call Toshiba help line at 800-575-5469. You will need the model number of yout TV that is listed on the front of the owner's manual. They are:

The first number will be the giveaway as to which model you have. It is the size of your set. They will ask you to try a hard reset. (Hold pwer button down for 5 seconds until you see the yellow light go solid and go off.) This will most likely not work. If it does, you are lucky. I found that if you unplug the TV for an extened period of time, ie overnight, ity may come back on. It will eventually give out completely though. Better to get the problem addressed with the manufacturer. If you are not under warranty then I do not know what to tell you. Right now I am searching the internet to see if I can find this part to maybe purchase myself. Only if it is not too costly. If I find anything I will post here for all. If you have any questions, feel free to email me a and I might be able to give you more details on your problem. Good Luck.

    I found the signal board part at

    My TV is the 42"HDLCD. It is model # 42HL67 and the part # is 75006083. It costs $155.72. I hope this helps.

    wkjtx here again. I have receiveed a number of inquiries regarding my original post to this problem and relative solutions.

    I later found out that the problem was not my signal board after the repair tech tried to fix it. (I WAS LUCKY TO BE UNDER WARRANTY STILL). The issue was with the SEINE BOARD.

    Make sure to ask about this problem if you receive word from the repair tech that your signal board is faulty. I have no way of knowing if this problem can be addessed by yourself. I do know that once the part FINALLY came in, that I had my TV back in a day. Be prepared to wait on the part though. Toshiba is very slow to react and rectify problems.

    You should be able to purchase the part online and possibly save your self a bit of money or time. Just do a bit of research.

I had the usual problem with a Toshiba 32HL67. Shortly after the warranty period ended, the TV would not turn on. The yellow light would blink three times ad infinitum until I unplugged the TV. After those incidents, the TV worked fine for about a year. Several weeks ago, the same problem started again.

Took the TV to a local repairman and discussed it with him. His thoughts were that it either involved the digital video board or the power supply. He suggested that I find the video board on the internet and let him install that. I located this part at for $49.95 plus shipping. Received it last week and had him install it. TV has worked fine since then. Got my fingers crossed.

The video board is Part V28A000320A1.

    I thought it best to do an addendum to my post from 03/03/10.

    With the new board installed, the TV comes on fine; however, when I did a scan to find over-the-air digital signals, it could not find any. This is not supposed to happen. This same TV with the old video board could find at least 10 transmitting digital channels.

    After doing some further research, it appears that this model TV has two different video boards. The one I installed was a PEO249A model. There is also a PEO361 model. This is the model that was originally in my TV. The full part number on it is V28A00043601. This difference may or may not be the reason I cannot get digital signals over the air.

    Anyone having the blinking yellow light problem should make certain which video board they have before ordering one. Both of these boards are available at internet stores for approximately the same price ($49.95 plus shipping at

    Given my experience, it appears that the two boards are not interchangeable. Of course, it would not matter if you are not trying to get over-the-air TV.

Haven't used our TV in six mos. It turned on OK but five minutes later turned off; but five minutes later turned on again but then turns off five minutes later. What to do? New TV or let it warm up?

Check all the connections of the flat cables inside the TV. Contact any service technician. If you wish to get some details; visit the site linked here. Pull up older posts.

Why does my tv shuts off soon after its turned on?

The Sceptre is a fine TV but is very sensitive to power surges.
If the unit turns off, soon after powering on, it is most likely the power supply.
Try disconnecting the power to the unit for 20 minutes and allow to completely cool down.

Re-connect the power and try the unit.

Hope it works for you

It's the problem of overheating in the power supply board of the TV.on the power supply board of the tv there are few capacitors and IC.any of this ic is got short or may be due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off. this is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will help in solving the problem...

The backlight controller is most likely faulty. It could be bad capacitors again, or the inverter board itself may need to be repaired - possibly faulty inverter(s). Try shining a torch close to the screen and see if you can see anything on the screen.

TV wont turn on, makes buzzing noise and shuts off

I have two RCA HD52W59 TV's. I have had one for 3 years and one 4 years. The one I have had for 4 years is giving me the problem. Last week the tv turned off while watching it. It wouldnt come right back on. 10 minutes later we tried and it worked fine. the other night the kids were watching and it turned off and smelled like something burning. I tried turning it right back on and got no power at all. I tried to turn it on two days later and it made a buzzing noise and the green light went out. Never did get a picture, no powering up on the screen. Any ideas? Don't want to spend alot of money. Really loved the TV hope it isnt junk now. Better yet I hope the same thing doesnt happen to the other one I have.

RCA Colortrak plus. Model# F32672SB Serial # 807560570 Chassis # CTC187CJ3 Manufacture Date Feb 1998 Service # F32672SBFM3 4/21/08- TV worked fine last night. This morning worked for about an hour. ...

It's probably a cracked solder joint in the power supply / horizonal drive stages. As the unit heats up the joint is seperating and breaking connection. It could also be a component failing when it gets hot. Usually the voltage regulator or Horizonal Output Transistor (both mount to heat sinks).

If you know how to solder and want to tinker, unplug the set for a couple days (to let the power capacitors discharge) and resolder and crystalized it cracked joints on the board(s) where the power stages, and flyback transformer are located.

If you decide to operate the set with the back off, please be careful. The high voltage on a TV can be 30,000+ volts.

Hope that helps,

TV refuses to stay on

I'm the OP of this, and what I did was had it unplugged for about 2 days, plugged it back in and it has worked since.
