I have a Toshiba rear projection tv model # 53HX71, sn 57908130, chassis # TAC0158.
I would like help in identifying the circuit board that would have the vertical stabilizer circuitry on it.

The picture rolls left to right very fast for about 20 minutes, then it slows down and you can watch a good picture with just a vertical white line running left to right about every 1 to 2 seconds.

Hi,
Thanks for the interest.
The menu? It rolls also I think. Not sure. The Guide rolls left to right as does the picture when warming up for 20 minutes or so. It slowly gets better and stops. Good picture, color, menu, guide, sound etc.
The white line that goes left to right seems to be separate from the picture. Not sure and it isn't hooked up now to check it.

Hello,
Thank you for your help with the Toshiba. I am an electronic tech from back in the vacuum tube days. 1968 etc. I have worked construction for my livelyhood for the last decades. Is it possible to help me identify the parts that you are suggesting that I check? I do not have an electrical schematic for this tv at present. I appreciate your time in trying to help me.

Hello,
How would I identify the hyper modue?

Hello Lcaillo,
I thank you for your help with a seudo blind man tech. I think I have enough posts to send a photo of my circuit board layouts. Would that help in your being able to point me in the right direction? I have some pics but can't seem to upload them here yet.

I posted a picture under General photos under TLS3028 Toshiba 53HX71.
Can you point me to the right area to take out the circuit board?
thanks,

Hi, After many distractions, I have removed the hyper module. I see a lot of 10 and 22 uf caps. I will try testing them from the component side.

 

[tls3028]

The degree of micro circuitry is a major challenge to the tools that I have at hand. I am wondering if attempting to buy a hyper board wouldn't be cheaper than the tool procurements that I would need. Is there a source for fair priced component boards?

 

[tls3028]

Thanks for the sources. I am on it.

 

[tls3028]

Thanks for the help. I will be procuring at Digikey. A guy there named Eric was really helpful in identification of my parts etc.

 

[tls3028]

Thank you for the tips all. I have ordered parts and tools. We shall see.

Hi, I finally got the time to go after the cap replacements on the hyper mod board today. I replaced all 10 & 22 smt caps and my installation was very rough to say the least. I ended up ripping loose a couple of solder pads on the board. I soldered jumpers to get the new caps installed. I am very pleased to say that the tv is working great at this moment. lcaillo knows his stuff. Thank you very much for your time and effort and guidance.
