Re: vs5065 Toshiba

Sounds like your vertical circuit is starting to go out. Probably the capacitors in that circuit. They are starting to leak and once charged up all way and warm they are holding. But it is only a matter of time before they go out and you will have the problem permanently. You should start looking for a reputable repair shop now. In fact, if you check out toshiba's website you should be able to find an authorized repair shop in your area. If there in none then check out the shops in your area. You should find one who is authorized with at least a couple of companies. Check on pricing. You should be able to get these caps replaced for around $100.00. Some companies will also come on site (yes, there are still some people who do house calls) though you will pay more for this service it saves you from draging the TV all over town. Anyway, this is not a problem you are going to be able to fix without some real electronic knowlege.

White horizontal lines covering picture on Toshiba 51HC85

The set uses a Hyper board inside that processes all signals, it is well known for this issue, board no longer available=reason is quite simple : about a dozen tiny surface mounted filter caps on that board with age dry out, at first it will work after warms up as poor caps regain some capacitance and seem to be ok.

Buy a new set, you can send that board out and have it repaired/rebuilt but the last one I saw which was under extended warranty cost about 200 just for the board rebuild.

In the last 4 years Here on Fixya I have encountered only 2 people who were able with instructions had the skill to remove the board and replace those caps, both were top notch computer repair techs.

Bad picture until tv warms up

this is a very common occurance in these sets. toshiba has issued a servece bullteen with this set. Sorry to tell you this but this is a problem with some very small capacitors on what is known as the hypermodule. in my shop we fix 2 to 5 of these a month. you really have to know how to solder. Idealy replace the hypermodule is the best way. but......that board is hard to find. so we replace these 11 very very small componets with twezzers and a big magnifier. we charge about 250 to 350 for this repair.

Picture Jumps/flashes for first 5 minutes

There is a module called a hyper board that is vertically mounted near the jack panel. Inside the module are 10mf/25v capacitors they are grtting weak. The module is fully shielded and pluggs into a socket. the module has 4 tabs (2 on each end) that must be unsoldered before it can be unplugged. This repair should be done by a qualified technician. The caps are surface mounts and very small. Unless you have excellent soldering skills and a rock steady hand DO NOT ATTEMPT to repair this problem on your own.

Picture "jumps" at startup for about 20 minutes until warm.

You have some leaky filter caps. They are: C2C52 = 10 MFD 50 VOLT (off the base of Q2C51 on the signal board)Also check C2P05 = 100 MFD 16 VOLT (off pin #3 of IC2P01 on the signal board) and C2P03,C2P08 = 100 MFD 16 VOLT both on the signal board.

Scrambling for first 15 mins

That is the exact problem I am currently having with my toshiba 50 in. I did some reading and it sounds like there is a temperature drift across one of the capacitors on the board and it takes longer and longer to warm up. Havent fixed it yet...
