(..) and most of the ics on the board i was unable to get a pinout or even get what they are exept the easy ones like de ttl logic gates z80 etc
Try harder! 
LH0080 is the Z80 CPU.
AY-3-8910A is a very well known soundchip (the "PSG"). Also known as YM2149.
M5L8255AP is Intel 8255 equivalent (the "PPI"). Even has its own Wikipedia article
Chip with the cooler on it will be the VDP. TMS9918A, TMS9929 or similar. Some small differences in function & pinout, but pinout is almost the same for all those variants.
HD27L019 is probably some kind of custom IC. Don't count on finding a pinout or datasheet for that anywhere. :( But given discrete PSG, PPI and other logic in the machine, there won't be much interesting stuff in it. Maybe some I/O address decoding, slot select logic or whatever.
YM2301 - sounds interesting but I'd bet it's a regular 32K*8 ROM with standard pinout.
HA11720 - probably a composite video encoder. Couldn't find a datasheet.
M5223L is some dual opamp. Datasheet here.
For parts where you have a pinout, it's easy to check connections to other IC's using a multimeter in low-range resistance setting. <1 Ohm or so = connection. Much higher = no (direct) connection.
Lacking a scope or logic probe, I'd try and find an external RAM cartridge + game cartridge and plug those in @ the same time. Might be that some RAM chip(s) has died and prevents the machine from booting.
Also, can you check how reset signal on various IC's responds to pressing the reset button? Easiest is if someone can give you a hand. You put multimeter on low voltage DC range, black test pin on a GND point, red pin on one of:
Z80 pin 26
VDP pin 34
8255 pin 35
Make note of voltage, have your helper press the reset button, see how voltage on IC pin responds, and make note of that too. Repeat for all points where you know an IC to have a reset input. Please post results?
Thanks guys for your replys Alexey and RetroTechie, before tuching anything more i like to test was was suggested before and use a ram rom cartrige to check. Today i received my mega sd flash + ram cart. Inserted it and know the computer works ! i can see the msx dos prompt on screen! 
. So this means problem lays on the rom or the ram ?.
Gonna test that later, thanks Alexey .
